Description
The present application is a divisional application of an invention patent application having an application date of 25/11/2003, application No. 200380104619.7, entitled "pharmaceutical composition containing basic or acidic pharmaceutical compound, surfactant, and physiologically acceptable water-soluble acid or base".
The present invention relates to novel pharmaceutical compositions, and in particular provides improved release and absorption of drugs, especially acid soluble drugs, for administration to the outer body cavity (e.g., gastrointestinal tract).
Many pharmaceutical compounds, having desirable therapeutic properties, cannot be effectively used due to their poor water solubility. Thus, for example, orally administered such compounds, only a small fraction of the drug is absorbed by the blood during gastrointestinal transit. Thus, to achieve adequate drug absorption, it may be desirable to administer high doses of the drug compound, to prolong the administration time, or to administer the drug compound multiple times. In fact, poor solubility and thus poor bioavailability of the drug may result in the poorly soluble drug being used in place of an alternative drug that may have undesirable side effects or require invasive administration (e.g., by injection or infusion).
One approach to poor solubility is to derivatize the drug molecule to introduce water-solubilizing groups, e.g., ionic groups such as carboxyl groups or non-ionic groups such as polyhydroxyalkyl groups, to obtain a soluble derivative. However, this approach is not always effective because of the potential failure to maintain a sufficiently high therapeutic efficacy and sufficiently low toxicity or other side effects. An example of a low solubility that is not replaced by a soluble derivative is the antibacterial agent itraconazole.
Attempts have therefore been made to enhance the uptake of e.g. itraconazole drugs by increasing the surface area of the drug compound exposed to saliva or gastric juice and to promote the dissolution of the drug compound by thin coating the drug compound onto the main inner carrier particles, e.g. sugar spheres. However, a disadvantage is that the volume of solid composition required for dosing the pharmaceutical compound is large, since the carrier significantly affects the overall dosing volume. The disadvantages of this approach are evident in the difficulties posed to the patient by the large number of capsules or tablets, or the large number of capsules or tablets of smaller volume.
Yet another approach is to use the drug compound in the form of a solution of the drug compound and a drug complexing agent such as cyclodextrin. This approach also has limitations in that the formulation must be such that it is capable of forming a complex with the cyclodextrin, the dosage is constrained by the solubilizing ability of the complexing agent, an easily incorporated solid dosage form cannot be used, and the drug compound is not gradually released for biological uptake.
The pharmaceutical compounds can also be formulated in the form of solid dispersions in cyclodextrins with physiologically tolerable water-soluble acids and physiologically tolerable water-soluble organic polymers. Reference is therefore made to WO 98/55148. This approach has limitations in that the formulations must be those capable of forming complexes with cyclodextrins and the dosage is constrained by the solubilizing ability of the complexing agent.
Another approach to increase the release of a drug from a dosage form and thereby increase the oral bioavailability of the drug is to use the drug with a suitable surfactant.
WO 97/35587 describes a liquid formulation comprising an HIV protease inhibitor together with a water-soluble tocopherol derivative, especially vitamin E-TPGS.
WO 98/08490 describes a dry solid co-precipitated composition comprising tocopherol polyethylene glycol succinate, a lipophilic active ingredient and a dispersing agent.
WO 99/26607 describes a solid dispersion of a drug and vitamin E TPGS.
WO 99/45918 describes compositions comprising a taxane, one or more surfactants and an acid. Acids are included in the formulation to improve the stability of the taxane.
WO 97/02017 describes solid dispersants containing a poorly soluble active ingredient in a hydrophilic polyhydroxylated hydrocarbon polymer. The solid dispersant may further contain an acid. The solid dispersion contains an acid to gradually provide the acid to facilitate dissolution of the active ingredient according to most release rate profiles.
The compositions of the present invention are significantly different from those provided in the prior art for rapid dissolution of the pharmaceutical compound and/or high solubility (resulting in a supersaturated state) of the pharmaceutical compound. This leads to an increase in the bioavailability of the pharmaceutical compound; the biological uptake of the drug compound is improved (the time parameter for improving the drug content in the plasma of the patient, e.g., the drug metabolism parameter as defined by AUC, Imax, Cmax, etc.). The pharmaceutical compounds incorporated in the compositions of the invention are also independent of the complex formulation, which makes the present compositions suitable for use in a wide range of pharmaceutical compound formulations.
We have now found that the above-mentioned features of the compositions of the present invention can be achieved by mixing a basic or acidic pharmaceutical compound with a surfactant and a significant amount of a water-soluble acid or base.
Thus, viewed from one aspect the invention provides a pharmaceutical composition comprising a basic pharmaceutical compound, a surfactant and a physiologically tolerable water soluble acid characterised in that the ratio of acid to pharmaceutical compound is at least 1: 1 by weight,
or
Comprising an acidic pharmaceutical compound, a surfactant and a physiologically tolerable water-soluble base, characterised in that the ratio of base to pharmaceutical compound is at least 1: 1 by weight.
In other words, the present invention provides a pharmaceutical composition comprising a basic or acidic pharmaceutical compound, a surfactant and a physiologically tolerable water soluble acid or base, characterised in that the ratio of acid or base to pharmaceutical compound is at least 1: 1 by weight.
Viewed from a further aspect the invention provides a method of use of a basic or acidic pharmaceutical compound, a surfactant and a physiologically tolerable water soluble acid or base in a ratio of acid or base to pharmaceutical compound of at least 1: 1 by weight for the manufacture of a pharmaceutical composition according to the invention for use in the prophylaxis, treatment or diagnosis of the human or non-human animal body (e.g. mammal, reptile or bird).
Still further, the present invention provides an improved method of prophylactic, therapeutic or diagnostic application to the human or non-human animal body (e.g. mammal, reptile or bird) comprising prophylactic, therapeutic or diagnostic application of a pharmaceutical composition to said body, an improved shuffled composition comprising the use of a composition according to the invention.
While not wishing to be bound by theory, potent drug compound dissolution parameters for the compositions of the present invention may be obtained as a result of a combination of the effects of exposing the components of the composition to water or aqueous fluids.
In compositions comprising a basic drug compound and a physiologically tolerable water soluble acid, the water and acid provide an acidic microenvironment that increases the solubility of the basic drug compound upon exposure to water or an aqueous liquid. The presence of the surfactant results in a further increase in the solubility of the drug compound to produce a supersaturated solution of the drug compound.
In a composition comprising an acidic drug compound and a physiologically tolerable water soluble base, upon administration, the water and base provide a basic microenvironment that increases the solubility of the acidic drug compound. The surfactant as described above results in the formation of a supersaturated state of the pharmaceutical compound.
The supersaturated solution produced by administration of the composition of the invention enhances the bioavailability of the pharmaceutical compound.
Since the compositions of the present invention may themselves provide an environment for increasing the solubility of the pharmaceutical compounds, they are administered orally at any time of day, independent of the food intake of the individual to whom they are administered.
Preferred compositions are those comprising a basic pharmaceutical compound, a surfactant and a physiologically tolerable water soluble acid, characterised in that the ratio of acid to pharmaceutical compound is at least 1: 1 by weight.
With respect to the surfactant in the present invention, any physiologically tolerable surfactant suitable for use in pharmaceutical compositions may be used.
The surfactant is an amphiphilic compound, which is well known in the art; it contains polar, hydrophilic groups and non-polar, hydrophobic groups.
The terms "hydrophilic" or "hydrophobic" are relative.
The relative hydrophilicity or hydrophobicity of a surfactant can be expressed in terms of its hydrophilic-lipophilic balance (HLB value). Surfactants with lower HLB values are classified as "hydrophobic" surfactants and surfactants with higher HLB values are classified as "hydrophilic" surfactants. Surfactants with HLB values greater than about 10 are conventionally considered to be hydrophilic surfactants; surfactants having HLB values less than about 10 are generally considered hydrophobic surfactants.
The composition of the present invention preferably contains a hydrophilic surfactant. It should be understood that the HLB value of a surfactant is only a rough indicator of the hydrophilicity/hydrophobicity of the surfactant. The HLB value of a particular surfactant may vary depending on the method used to determine the HLB value; may vary depending on its commercial source; depending on the batch to batch variation. Hydrophilic surfactants suitable for use in the pharmaceutical compositions of the present invention can be readily determined by one skilled in the art.
The surfactant of the present invention may be an anionic, cationic, zwitterionic or nonionic surfactant, the latter being preferred. The surfactant of the present invention may also be a mixture of two or more surfactants.
The choice of surfactant may be dictated by the particular compound used in the composition of the present invention. Thus, surfactants with greater solubility, having an increased ability to provide a supersaturated environment, are preferred for use with particular pharmaceutical compounds.

It should be emphasized that this list of surfactants is illustrative, representative and not exhaustive in any way. Therefore, the present invention is not limited to the surfactants listed below.

Among the suitable surfactants listed above, different possibilities are listed such as PEG-20 oleyl ether or cetyl ether or stearyl ether, which means that PEG-20 oleyl ether and PEG-20 cetyl ether and PEG-20 stearyl ether are meant. Thus, for example, PEG-20 castor oil or hydrogenated castor oil or corn glycerides or hydrogenated walnut glycerides would be read as PEG-20 castor oil and PEG-20 hydrogenated castor oil and PEG-20 corn glycerides and PEG-20 hydrogenated walnut glycerides.
In the compositions of the present invention, the surfactant is preferably present in an amount of 1 to 70% by weight, more preferably 5 to 55%, most preferably 10 to 50% (relative to the total weight of surfactant, acid and drug). The amount of surfactant used will then generally depend on the amount of drug and the drug compound itself. The ratio by weight of surfactant to drug is preferably in the range 100: 1 to 1: 5, especially 50: 1 to 1: 2, more especially 10: 1 to 1: 1.
Preferred surfactants in the compositions of the present invention belong to the group of polyethylene glycol sorbitan fatty acid esters, the group of products of alcohol-oil transesterification, or the group of polyoxy vinyl-polyoxypropylene block copolymers. Preferably, the surfactant in the composition of the invention belongs to the group of fatty acid esters of polyethylene glycol sorbitan or to the group of products of alcohol-oil transesterification. The most preferred surfactants are those known as Tween, those known as Cremophor, and vitamin E TPGS (alpha-tocopheryl-polyethylene glycol succinate, also abbreviated as TGPS), especially Cremophor RH40 and vitamin ETPGS.
As another example of the composition of the present invention, the surfactant may be substituted with a suitable wax, such as polyethylene glycol and the like.
The acid used in the compositions of the present invention may be any water-soluble physiologically tolerable acid, especially any inorganic acid conventionally used in the preparation of acid salts of pharmaceutical compounds, or, more preferably, organic acids such as acetic, fumaric, tartaric, maleic, malic, succinic, oxalic, malonic, benzoic, mandelic and ascorbic acids.
Tartaric acid and more particularly citric acid are preferred because their salts with pharmaceutical compounds generally have a reduced tendency to precipitate from aqueous solutions. In general, however, any acid may be used as long as it is not so strong as to promote degradation of the surfactant and when added to water can create a low pH environment, preferably pH4 and ideally about pH 2. The acid may be in liquid (e.g., solution) or solid form; however, solid acids in the form of anhydrous or hydrates in the surrounding environment are preferred.
The base used in the compositions of the invention may be any water-soluble physiologically tolerable base, especially any inorganic or organic base conventionally used for the preparation of basic salts of pharmaceutical compounds, e.g. alkali and alkaline earth metals, e.g. lithium-, sodium-, potassium-, magnesium or calcium hydroxide, bicarbonates or carbonates, etc., NH3N, N' -dibenzylethylenediamine, N-methyl-D-glucamine, hydrated amine, ethanolamine, diethanolamine, triethanolamine and the like, amino acids such as arginine, lysine and the like.
In the compositions of the present invention, the acid is present in a ratio of at least 1: 1 acid to drug by weight, preferably in a ratio of from 1: 1 to 100: 1 acid to drug by weight, more preferably from 1: 1 to 50: 1, even more preferably from 1: 1 to 10: 1 and most preferably from 3: 1 to 10: 1. The amount of acid used will depend on the acid and drug compound chosen, but generally an increase in the relative proportion of acid will result in accelerated dissolution of the drug upon contact with water. Generally, the amount of acid is at least that amount necessary to create an acidic microenvironment upon contact with water, particularly aqueous solutions, in which the solubility of the pharmaceutical compound is increased.
The acid is an important component of the composition of the present invention and it rapidly dissolves in the liquid. The invention therefore also relates to a pharmaceutical composition comprising a basic pharmaceutical compound, a surfactant and a physiologically tolerable water-soluble acid, characterized in that the weight percentage of acid by weight is in the range from 30% to 95%, preferably from 45% to 95%, more preferably from 50% to 90%, most preferably from 50% to 65%. The weight percentages by weight preferably correspond to the weight of the basic pharmaceutical compound, the surfactant and the physiologically tolerable water-soluble acid and the optional polymer.
Alternatively, the invention also relates to a pharmaceutical composition comprising a basic pharmaceutical compound, a surfactant and a physiologically tolerable water soluble acid, characterised in that the molar ratio of acid to pharmaceutical compound is at least 3: 1, preferably at least 5: 1, more preferably at least 10: 1.
The invention also relates to a pharmaceutical composition comprising a basic pharmaceutical compound, a surfactant and a physiologically tolerable water-soluble acid, characterized in that the weight percentage of acid is in the range from 30 to 95% by weight and in that the ratio of acid to pharmaceutical compound is at least 1: 1 by weight.
Alternatively, the invention also relates to a pharmaceutical composition comprising a basic compound, a surfactant, a physiologically tolerable water-soluble acid, characterized in that the weight percentage of acid by weight is between 30% and 95% and in that the molar ratio of acid to pharmaceutical compound is at least 3: 1.
The particular values of the acids set forth above also account for the bases in the compositions of the present invention which comprise the acidic drug compound, the surfactant, and the base.
The most specific advantage of the composition of the invention is that the pharmaceutical compound is only poorly soluble, but the drug dissolution parameters obtained by the combination of the drug, the surfactant and the acid (or base) are so significant that significantly improved drug uptake parameters can be obtained in which the pharmaceutical compound is more soluble.
Thus, the pharmaceutical compound in the composition of the invention may be any organic or inorganic substance. Pharmaceutical compounds can exert local physiological effects, as well as systemic effects, whether after passage through the mucosa or after transfer to the gastrointestinal tract with saliva upon oral administration.
Preferably, the pharmaceutical compound is not readily soluble, e.g., not readily soluble, slightly soluble, poorly soluble, or insoluble in purified water at 21 ℃ (i.e., it is desired to dissolve 1 part of the pharmaceutical compound in solution with 30, 100, 1000, 10000 parts by weight of water). In particular, the drug is a basic drug compound. The term basic drug compound refers to a drug compound having a pKa value above 7 or a drug compound that is soluble in an acid/acidic medium. The term acidic drug compound refers to a drug compound having a pKa value below 7 or a drug compound that is soluble in a base/alkaline (alkaline) medium.

For therapeutic use, salts of the pharmaceutical compounds are those in which the counterion is pharmaceutically acceptable. However, salts of acids and bases that are not pharmaceutically acceptable may also be used, for example, in the preparation or purification of a pharmaceutically acceptable compound. All salts, whether pharmaceutically acceptable or not, are included within the scope of the invention.
The aforementioned pharmaceutically acceptable addition salts refer to the non-toxic acid addition salt forms which the pharmaceutical compounds may form, comprising therapeutic activity. The latter are suitably obtained by treating the base with a suitable acid, for example, hydrohalic acids, e.g., hydrochloric acid, hydrobromic acid, and the like; sulfuric acid; nitric acid; phosphoric acid, and the like; or an organic acid such as acetic acid, propionic acid, hydroxyacetic acid, 2-hydroxy-propionic acid, 2-ketopropionic acid, oxalic acid, malonic acid, succinic acid, cis-butenedioic acid, trans-butenedioic acid, malic acid, tartaric acid, 2-hydroxy-1, 2, 3-propanetricarboxylic acid, methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, 4-methylbenzenesulfonic acid, cyclohexanesulfonic acid, 2-hydroxybenzoic acid, 4-amino-2-hydroxybenzoic acid, and the like.

Suitable base forms include, for example, lithium, sodium, potassium, magnesium and calcium salts and the like, salts with organic bases, for example, primary, secondary and tertiary aliphatic and aromatic amines such as methylamine, ethylamine, propylamine, isopropylamine, the four butylamine isomers, dimethylamine, diethylamine, diethanolamine, dipropylamine, diisopropylamine, di-N-butylamine, tetrahydropyrrole, hexahydropyridine, morpholine, trimethylamine, triethylamine, tripropylamine, quinuclidine, pyridine, quinoline and isoquinoline, phenothiazine, N-methyl-D-glucamine, 2-amino-2- (hydroxymethyl) -1, 3-propanediol, hydrated amine salts and salts with amino acids, for example, arginine, lysine and the like. The salt form, in turn, can be converted to the free acid form by acid treatment.
The term addition salt also encompasses hydrates and solvates which the pharmaceutical compounds may form. Examples of these forms are hydrates, alcoholates and the like.
The term "quaternary ammonium" is used herein to define quaternary ammonium salts which may be formed from a pharmaceutical compound by reaction of a basic nitrogen atom with a suitable quaternizing agent, for example, an optionally substituted alkyl halide, aryl halide or arylalkyl halide, e.g., methyl iodide or benzyl iodide. Other reactants having good leaving groups may be used, such as alkyltrifluoromethane sulfonates, alkyl methane sulfonates, and alkyl p-toluene sulfonates. The quaternary ammonium salt has a positively charged nitrogen atom. Pharmaceutically acceptable counterions include chloride, bromide, iodide, trifluoroacetate and acetate. The selection of the counterions can be performed using ion exchange resins.
By N-oxide form is meant that one or several of the trivalent nitrogens comprising the pharmaceutical compound is oxidized to the so-called N-oxide.
It will be appreciated that some of the pharmaceutical compounds and their N-oxides, addition salts, quaternary ammonium salts and stereochemically isomeric forms may contain one or more chiral centers and exist as stereochemically isomeric forms.
The term "stereochemically isomeric forms" in all the preceding paragraphs defines all possible stereoisomers of the pharmaceutical compounds, their N-oxides, addition salts, quaternary ammonium salts or physiologically functional derivatives. Unless otherwise mentioned or indicated, the chemical designation of a compound refers to a mixture of all possible stereochemically isomeric forms, which comprises all diastereomers and enantiomers of the basic molecular structure as well as each isomer and its N-oxide, salt, solvate or essentially free quaternary ammonium, i.e. admixed with less than 10%, preferably less than 5%, especially less than 2% and most preferably less than 1% of the other isomers. Thus, when the compound of formula (I) is specifically (E), this means that the compound is substantially free of the (Z) isomer.
In particular, the chiral centers may have an R-or S-conformation; the substitution of the saturated groups of the divalent ring (moiety) can be in either the cis-or trans-conformation. Compounds containing a double bond may have the stereochemistry of e (entgegen) or z (zusammen) at the double bond. The terms cis, trans, R, S, E and Z are well known to those skilled in the art.
Stereochemical isomers of the pharmaceutical compounds are clearly within the scope of the present invention.
Some pharmaceutical compounds may also exist in their tautomeric forms. These forms, although indicated in the above structural formulae, are also included in the scope of the present invention.

The compound in the present invention may further comprise an organic polymer.
As previously mentioned, supersaturated solutions of pharmaceutical compounds produced by the components of the compounds when exposed to water can be stabilized by virtue of the viscosity enhancing effect of the organic polymer. The organic polymer may hinder the precipitation of the drug compound as more water enters so that the microenvironment becomes more dilute.
The organic polymer used in the compounds of the present invention may be any pharmacologically acceptable water-soluble synthetic, semi-synthetic or non-synthetic organic polymer.
Thus, for example, the polymer may be a natural polymer, such as a polysaccharide or polypeptide or derivative thereof, or may be a synthetic polymer, such as a polyalkylene oxide (e.g., PEG), polyacrylate, polyvinylpyrrolidone, or the like. It is also possible to use mixed polymers, such as block copolymers and glycopeptides.
It is believed that the effect of the organic polymer, which is dissolved in the compound of the invention for stabilizing supersaturated solutions of the pharmaceutical compound, is caused by an increase in viscosity, the polymer typically having a molecular weight in the range of from 500D to 2MD and typically having an apparent viscosity of from 1 to 100mpa.s in a 2% aqueous solution at 20 ℃. For example, the water-soluble polymer may be selected from the group comprising:
alkylcelluloses, such as methylcellulose,
hydroxyalkyl celluloses, such as hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose and hydroxybutyl cellulose,
hydroxyalkyl alkylcelluloses, such as hydroxyethyl methylcellulose and hydroxypropyl methylcellulose,
carboxyalkylcelluloses, e.g. carboxymethyl cellulose
Alkali metal salts of carboxyalkylcelluloses, such as sodium carboxymethylcellulose,
carboxyalkylalkylcelluloses, such as carboxymethylethylcellulose,
-carboxyalkylcellulose esters of cellulose,
-a group of starches,
pectins, such as carboxymethyl amyl pectin,
chitin derivatives, such as chitosan,
-a source of heparin and heparinoids,
polysaccharides, such as alginic acid, its alkali metal and ammonium salts, carrageenan, galactomannan, tragacanth, agar, gum arabic, guar gum and xanthan gum,
-polyacrylic acids and salts thereof,
polymethacrylic acids and salts thereof, copolymers of methyl acrylate,
-a polyvinyl alcohol (PVA),
-polyvinylpyrrolidone) copolymers of polyvinylpyrrolidone with vinyl acetate,
polyoxyalkylenes, such as polyethylene oxide and polypropylene oxide and copolymers of ethylene oxide and propylene oxide, such as polyhydroxyalkylenes (poloxamers) and polyhydroxyimines (poloxamines).
Polymers not listed which are pharmaceutically acceptable and which have the appropriate physicochemical properties as defined hereinbefore are also suitable for preparing the compositions of the invention.
Preferred organic polymers are cellulose ethers, such as methylcellulose, hydroxyethylmethaneCellulose based, or hydroxypropyl methylcellulose (HPMC), e.g. MethocelTM(from Colorcon, UK.) such as MethocelTM A、MethocelTM E、MethocelTM F、MethocelTM K、MethocelTMJ and MethocelTMHB, or e.g. MetholoseTME.g. MetoloseTM SM、MetoloseTMSH or MetholoseTMAnd (SE). The most preferred organic polymer is hydroxypropyl methylcellulose, for example from 5cps MethocelTME to 15000cpsMethocelTMK15M.
The effective action of the compositions of the invention can be achieved even with very small masses of organic polymers. Thus, the organic polymer in the composition of the present invention may be present in an amount of 0.05 to 35% by weight, preferably 0.1 to 20%, more preferably 0.5 to 15%, most preferably 2 to 11% by weight (relative to the total mass of the pharmaceutical compound, acid or base, surfactant and organic polymer). Both the content of organic polymer and the viscosity grade affect the dissolution of the pharmaceutical compound in the composition of the invention, increasing the content of organic polymer and/or increasing the viscosity grade (e.g. 15000mpa.s instead of 5mpa.s (mpa.s in a 2% aqueous solution at 20 c)) both have a tendency to slow the dissolution of the pharmaceutical compound. The identity and amount of organic polymer is therefore generally selected according to the desired state of dissolution. For example, a water-soluble polymer having an apparent viscosity of greater than 1000mPa.s, dissolved in a 2% aqueous solution at 20 ℃, provides a sustained release of the drug.
Thus, the composition according to the invention may in this way be designed to provide a particularly advantageous drug dissolution release. For example, dissolution may be fast enough to determine that the pharmaceutical compound is actually fully bioavailable (e.g., by mouth, nose, stomach, or vagina), but slow enough to provide a longer-term plasma intake state, e.g., to avoid re-precipitation of the pharmaceutical composition before it reaches the stomach.
A preferred embodiment is a pharmaceutical compound comprising a basic pharmaceutical compound, a surfactant, a physiologically acceptable water-soluble acid and optionally an organic polymer, characterized in that the pharmaceutical compound is in the form of a solution in said hydrochloric acid after addition of said composition containing 100mg of said pharmaceutical compound in amounts of 7 to 25 (preferably 10 to 20, especially 12 to 18)%, 45 to 70 (preferably 50 to 65, especially 54 to 63)% and at least 96 (preferably at least 97, especially at least 98)% for 5, 15 and 45 minutes, respectively, to 600ml of 0.1N hydrochloric acid at 37 ℃. These data are consistent with the study of USP23, <711> dissolution, page 1791-.
For example, the dissolution state proposed hereinbefore is determined by placing the composition in 0.1N HCl (or other suitable medium) either uncoated or in a rapidly dissolving coating (e.g. gelatin capsule shell) and slurrying using the USP-method, apparatus 2, stirring at 50 or 100 rpm.
The compositions of the invention may if desired be aqueous, but are generally preferably substantially anhydrous, e.g. containing up to 3% by weight, preferably less than 1% by weight, and most preferably less than 0.5% water, but may be mixed with water immediately prior to administration or may be coated and dispersed in an aqueous medium, the coating being broken only after administration. Such water-soluble compositions are considered to be within the scope of the present invention.
Depending on the choice of the components, the compositions of the invention may be in liquid, solid or semi-solid form-for example, in the form of a gel. The composition is preferably non-free flowing rather than free flowing particles at ambient temperature (e.g., 21 ℃). Thus the composition is preferably a solid or semi-solid state, or less preferably a highly viscous fluid, at ambient temperature.
The pharmaceutical compound, surfactant, acid or base and the selected organic polymer in the composition of the present invention are intimately mixed together.
Thus, where the composition is a particulate, the acid (base), the pharmaceutical compound, the surfactant and the selected organic polymer are mixed together within the particle (e.g., on a molecular scale; this can be used to separate the solvent from a solution of these components so that a solid or semi-solid dispersion is formed). Individual particles in the granular mixture do not contain all three or selected four of the constituent components, or it may be desirable to encapsulate a core of one or more of the constituent components with other constituent components. Such intimate admixture is important because the components of the present invention, as previously described, assist at the microscopic level when dissolved.
Preferably, all the constituent components are dispersed so as to form a system of balanced chemical and physical properties or homogeneous overall, or consist of one phase as defined in thermodynamics; such a dispersion will be referred to hereinafter as a thermoplastic phase or thermoplastic system. The components of the thermoplastic system are rapidly bioavailable to the organism to which it is administered. This advantage can be explained by the fact that thermoplastic systems readily form liquid solutions when in contact with body fluids such as gastric juices. The fact that it is readily soluble can be attributed, at least in part, to the fact that the energy required to dissolve the constituent from the thermoplastic system is less than the energy required to dissolve the constituent from the crystalline or microcrystalline solid phase.
The term "solid dispersion" as used hereinbefore and hereinafter refers to a system comprising the components of the composition of the invention in the solid state (as opposed to the liquid or gaseous state), wherein one of the components is more or less evenly dispersed throughout the other component (which may include additional pharmaceutically acceptable formulation agents, such as plasticizers, preservatives and the like, generally known in the art). When the dispersion of constituents is such a chemically and physically balanced or entirely homogeneous system, or a phase as defined in thermodynamics; such a solid dispersion will be referred to as a "solid solution". Solid solutions are the preferred physical system because the components therein are generally rapidly bioavailable to the organism to which it is administered. This advantage can be explained by the ease with which the solid solution can form a liquid solution upon contact with a liquid medium, such as gastrointestinal fluid. The fact that it is readily soluble can be attributed, at least in part, to the fact that the energy required to dissolve from a solid solution is less than the energy required to dissolve the constituent from a crystalline or microcrystalline solid phase.
The term "solid dispersion" also encompasses dispersions that are less homogeneous overall than solid solutions. These dispersions are not chemically or physically homogeneous throughout or contain more than one phase. For example, the term "solid dispersion" also relates to a system having a specific structural part or small region of a macromolecule, wherein an amorphous, microcrystalline or crystalline drug compound, and/or an amorphous, microcrystalline or crystalline surfactant, and/or an amorphous, microcrystalline or crystalline acid or a selected amorphous, microcrystalline or crystalline polymer is dispersed more or less homogeneously in another phase comprising a solid solution, which comprises the drug compound, the surfactant, the acid (base) and the selected polymer. The particular structural moiety of the macromolecule is a region within the solid dispersion that is marked by some distinct physical characteristic and by small size that is uniformly and randomly distributed throughout the solid dispersion.
The compositions of the present invention may be obtained by preparing an intimate mixture of the pharmaceutical compound, the surfactant, the acid (base) and the selected organic polymer. This may be directly affected by the process of removing the solvent after dissolving these ingredients in the liquid solvent. Thus, in the long term, the present invention provides a process for preparing a pharmaceutical composition, namely: dissolving a pharmaceutical compound, a surfactant, a physiologically tolerable water soluble acid (base), and a selected physiologically tolerable organic polymer in a solvent; removing the solvent from the solution obtained above; optionally shaping the resulting product into a desired shape; the product is coated with a coating material that is acceptable in physiological conditions.
Alternatively, if the components of the composition are stable to heat, the components may be co-melted to produce a physical mixture thereof. Accordingly, the present invention also provides a process for preparing a formulation composition, namely: co-melting a pharmaceutical compound, a surfactant, a physiologically tolerable water soluble acid (base), and a selected physiologically tolerable water soluble organic polymer; forming the obtained product into a desired shape; the product is coated with a physiologically tolerable coating material.
In particular, the above process can be accomplished by using one of the following techniques:
a) spray drying:
the components of the present composition may be dissolved in a suitable solvent, and the resulting solution may be spray-dried to obtain a powder. These powders may be further processed into exemplary tablets or filled into capsules.
b) And (3) freeze drying:
the ingredients of the present composition may be dissolved in a suitable solvent and the resulting solution may be freeze-dried to provide a powder which may be tableted or encapsulated. Alternatively, the solution can be freeze dried directly in a mold suitable for blister packs to give a shape suitable for blister packs.
c) Supercritical fluid technology:
the ingredients of the present composition may be dissolved in a compressible fluid, especially a supercritical fluid (i.e. any substance above the critical temperature and critical pressure, the supercritical fluid having gas and liquid properties) (in this case, supercritical fluid refers to a solvent; and thus can be referred to as a standard such as RESS (rapid expansion of supercritical solution) or PGSS (particles in gas saturated solution)), followed by removal of the supercritical fluid using supercritical techniques (e.g. pressure reduction) and thus obtaining a powder which can be further tableted or encapsulated. The supercritical fluid technique can also be applied to supercritical fluid as an antisolvent (reference such as GAS antisolvent), SEDS (supercritical fluid adds dispersed solvent), ASES (aerosol solvent extraction system), SAS (supercritical antisolvent) or PCA (compressed antisolvent precipitation)). In this case, the ingredients of the composition are dissolved in a suitable solvent and a supercritical fluid is used to increase the solvent evaporation, thus obtaining powders which can be further used for the above-mentioned purposes.
d) Coating a carrier:
the ingredients of the present composition may be dissolved in a suitable solvent, and the resulting solution may be coated, sprayed, or granulated by volatilizing the solvent on a suitable carrier. Suitable carriers which can be used depend on the technique used, e.g. the use of microcrystalline cellulose as carrier for the preparation of micropellets using a fluidized bed apparatus, or the use of gas phase SiO for granulation2The carrier is prepared by using a high shear granulator or by spraying a solution of the ingredients of the composition onto an inert core, such as sugar beads. The solvent is removed by techniques such as high temperature vacuum drying, vacuum drying or microwave.
e) Co-melting:
when the ingredients in the composition are stable to heat, they may be physically mixed, melted and then mixed. The molten mixture can be directly formed into the desired shape (milled, pressed; injection molded), for example the melt can be directly poured or injected, e.g. into the final blister pack, or directly into a mould, or directly into a capsule, followed by coating. The molten mixture may also be cooled prior to processing, such as grinding to a powder and tableting or encapsulating. The ingredients of the present composition may be made as a eutectic by simply heating the physical mixture or melt extruding the same. In the latter case, the components are physically mixed and then fed into an extruder at an elevated temperature, where the mixture is heated to melt and form a mixture, after which the resulting molten extrudate is shaped by the methods described above, e.g., injected into a mold or the molten extrudate can be cooled and then ground into a powder for tableting or encapsulation.
Alternatively, the melt may be granulated (melt granulation; high shear granulation), sprayed or coated on a suitable carrier (see item d). Melt granulation may be carried out in a melt extruder, with the carrier being added during extrusion, and the extrudate obtained being shaped by the methods described above. When the carrier employed is an excipient suitable for spheronization, the resulting extrudate may be spheronized using a pellet mill.
f) Extruding:
the ingredients of the present composition may be mixed and fed into an extruder, such as through a dry powder feeder, and a solvent containing a suitable surfactant may be added to the extruder, such as through an air inlet. While the mixture was still in the extruder, the solvent was evaporated off. After extrusion, the extrudate is shaped (milling, crushing).
Alternatively, the solution containing the ingredients of the composition of the invention is fed into an extruder, the solvent is evaporated while the product is still in the extruder, and the extrudate is finally shaped.
Alternatively, a solution containing the ingredients of the present composition is granulated on a suitable carrier, such as microcrystalline cellulose, extruded as a wet powder. The extrudate was spheronized by a pellet mill, after which the resulting pellets were dried to remove the solvent. The pellets can be directly filled into capsules or prepared into tablets.
Preferably, the present composition is prepared by the extrusion process described in f. The skilled worker is able to carry out the appropriate steps and process parameters in order to extrude a solution containing the constituents of the composition and to evaporate the solvent in the extruder. See patent WO 98/10752.
The solvents used in the above process are finally physiologically tolerable materials, suitable organic solvents such as alkanols having from 1 to 6 carbon atoms (e.g. ethanol), acetone, N, N-dimethylformamide, linear or cyclic ethers (e.g. diethyl ether, dimethyl ether or tetrahydrofuran), cyclohexane, dimethyl sulfoxide, etc., or solvent mixtures are employed which may contain water. For acids with higher melting points, solvents or solvent mixtures with high boiling points can be conveniently used; however, in general, the boiling point of the solvent or solvent mixture does not exceed 100 ℃. Such solvents can be effectively used in the preparation of the compositions of the present invention with little solvent residue. The solvent may be conveniently removed by evaporation, for example under reduced pressure, and since this may result in some solvent remaining (e.g. more than 3%), it is recommended to use pharmaceutical excipients such as ethanol (or alcohol-water mixed solvents) which are acceptable for use.
As described above, a supercritical fluid may be used. Suitable supercritical fluids such as CO2,N2O,N2Short-chain alkanes, such as methane, ethane and the like.
If the pharmaceutical compound is insoluble or poorly soluble in the selected solvent, the process of the present invention may include a particulate dispersion (e.g., nanoparticles having a particle size of 1-100 nm) of the pharmaceutical compound in the solvent, rather than completely dissolving the pharmaceutical compound. If this step is carried out, the smaller the particle size of the pharmaceutical compound, the better. Nanoparticles of insoluble compounds can be prepared, for example, by various precipitation techniques or by co-milling with physiologically tolerable inorganic substances, such as zirconium oxide (EP-0,499,299).
Removal of the solvent may or may not be complete, the former producing a solid or gelatinous solid or semi-solid, the latter possibly resulting in a viscous liquid that can be encapsulated.
Generally, complete removal of the solvent is preferred, since the resulting product is readily settable. It has been mentioned above that spray drying of the solution (to obtain a granular product), volatilization of the solvent in a mold, shaping (e.g. injection molding), extrusion, etc. are effective shaping methods. As described above, the product may be prepared while heating and solidified upon cooling. The shaped product can be formed into a film or tablet form by evaporating the solvent or pouring the hot mass onto a disk to evaporate the solvent.
In a preferred embodiment, the product is filled (e.g., poured or extruded or injected) into a capsule shell, such as a gelatin capsule.
Another procedure for preparing the compositions of the present invention is to prepare a dispersion of the above-mentioned pharmaceutical compound, surfactant and acid (base) and mix to obtain a physical mixture of the product and the organic polymer.
Yet another process for preparing the present compositions is to prepare a dispersion of the pharmaceutical compound, the acid (base) and the selected organic polymer by dissolving them in a solvent, followed by removal of the solvent and mixing the resulting product with the surfactant at elevated temperature. It is within the skill of the skilled artisan to select the most appropriate parameters and equipment for the above procedure.
The skilled artisan will appreciate that the particle size, particle size distribution, crystallinity and morphology of the resulting powder will depend on the process of preparation and that specific requirements may be met by adjusting process parameters such as temperature, nozzle size, nozzle shape, gas flow during spraying.
The pharmaceutical composition of the present invention may be formulated into a suitable dosage form.
Thus, in the foregoing the invention provides a formulation containing a therapeutically effective amount of the composition.
For example, if the drug is delivered in standard capsules (e.g., a 900mg capacity glass thermoplastic system as described herein, with a desired drug loading of 100 mg/capsule), the amounts and properties of the other composition components will need to be selected to produce a preferred drug dissolution profile, typically requiring the use of a smaller amount of organic polymer, e.g., 20-50mg, and the ratio of acid (base) to surfactant can be set as required for the dissolution profile, e.g., 200-400mg surfactant corresponds to 450-650mg acid (base).
In addition to the pharmaceutical compound, organic polymer, acid (base) and surfactant, the composition of the present invention may contain other conventional pharmaceutical adjuvants such as sweeteners, colorants, antioxidants, fillers, glidants, lubricants, fats, waxes, coating solutions, dispersants, suspending agents (e.g., the composition is coated with a gastric acid resistant material and then dispersed in water or syrup), and the like. Such ingredients are typically present in small proportions, e.g., 0.01% to 10% by mass (compared to the sum of the masses of acid (base), surfactant, drug compound and organic polymer), and thus can be mixed directly with the drug compound. However, when the compositions of the present invention are encapsulated or otherwise disposed in a carrier (e.g., a liquid, solid, or semi-solid matrix), the proportion of such excipients (e.g., coating materials, encapsulating materials, dispersion media, etc.) may be smaller or larger, e.g., 5-95%, and not directly mixed with the pharmaceutical compound.
The product may be hygroscopic and thus may give a sticky feel when touched by hand due to absorption of moisture from the skin. It is therefore desirable to coat the product to prevent water uptake during processing. Such coatings may take the form of capsules (as described above), tablet coatings, protective films or wet coatings, removable water-resistant wraps. Tablet coatings may be applied in a conventional manner, may be dissolved in the mouth or stomach (e.g., sugar or sugar/beeswax coatings), or may be coated with a polymer resistant to gastric acid (e.g., with a coating of a polymer resistant to gastric acid when drug uptake in the small intestine is desiredGastric acid resistant Eudragit produced by GmbHTMCoated products). The protective film or wrap is used in conjunction with topical application of the product, such as absorption through the skin or toes or nails. In this case, the composition pad is placed between the upper protective layer having adhesive properties and the lower removable layer. Examples of topical application forms applied to the nails and adjacent tissues are the treatment of fungal infections, see US-A-5182914.
The composition may also contain a suitable lubricant, such as sodium stearate, to avoid stickiness.
When the product is formulated in a specific manner, e.g. spray drying, the particles may be contained in a sealed delivery device (e.g. a spray device or a powder device such as an inhaler) for oral, nasal or topical administration of the particles. Alternatively, it can be encapsulated or mixed with filler such as lactose, starch, and microcrystalline cellulose, and the obtained mixture is tableted. In any case, the particles may require one or more coatings, such as delayed release or extended release formulations.
However, it is generally preferred to formulate the product as discrete doses and therefore require protective coatings such as capsules, coated tablets or film-coated single doses.
The compositions of the present invention may be formulated for convenient topical application or for administration into a completely empty body cavity, such as the nose, lungs, mouth, ear, stomach, rectum or vagina. Although more particularly capsules and coated tablets are preferred for patches and powders, topical administration forms include patches, tablets, troches, lozenges, earplugs, nasal plugs, coated tablets, capsules, suppositories, chewable tablets, gels, powders, granules, syrups and dispersions. The dosage form depends on the pharmaceutical compound and the treatment environment, as well as the class size of the patient.
