Description

PHARMACEUTICAL COMPOSITION The present invention relates to a novel pharmaceutical composition for the oral delivery of pharmaceutical compounds, in particular poly- (amino acids), including peptides or, in an alternative manner, peptidomimetics. In particular, the present invention relates, in one embodiment, to a novel oral pharmaceutical composition containing a poly- (amino acid), for the treatment of a disorder caused by abnormal bone resorption, and / or to the treatment of an arthritic condition, and another subject matter. Background of the Invention Hormones The poly- (amino acids) that have been used or proposed to be used for pharmaceutical or veterinary purposes include, but are not limited to, the following sources, including synthetic, natural or recombinant thereof: polypeptide hormones, such as calcitonins, for example, salmon calcitonin, growth hormone, including human growth hormones (hGH), recombinant human growth hormones (rhGH), bovine growth hormones, and porcine growth hormones; growth hormone-releasing hormones, and pituitary thyroid hormone. The parathyroid hormone or PTH can be the full-length form of 84 amino acids of the parathyroid hormone, by example, the human form, hPTH (1-84), or any polypeptide, protein, protein fragment, or modified fragment, ie, peptides related to the parathyroid hormone and parathyroid hormone analogs, capable of mimicking the activity of hPTH ( 1-84) in the control of calcium and phosphate metabolism, to build bone in the human body. In general terms, the parathyroid hormone fragments will incorporate at least the first 28 N-terminal residues, and will include, for example, PTH (1-28), PTH (1-31), PTH (1-34), PTH (1-37), PTH (1-38) and PTH (1-41) and analogs thereof, for example, PTS893. The parathyroid hormone can be a single parathyroid hormone or any combination of two or more parathyroid hormones. The preferred parathyroid hormone fragment is PTH (1-34). These parathyroid hormones are commercially available, or can be obtained in a recombinant manner, by peptide synthesis, or by extraction from the human fluid, by methods well established in the art. The amount of parathyroid hormone that is to be administered is generally an effective amount to stimulate the new bone formation, i.e., a therapeutically effective amount. This amount will necessarily vary with the age, size, sex, and condition of the subject to be treated, the nature and severity of the disorder to be treated, and the like. However, the unit amount may be less than the dosage described, when a plurality of the compositions, that is, the total effective amount can be administered in cumulative dosage units. The unit amount of parathyroid hormone may also be greater than the effective amount when the composition provides a sustained release of the pharmacologically active agent. The total amount of parathyroid hormone that should be used can be determined by methods known to those skilled in the art. However, in general, satisfactory results will be obtained systemically with daily dosages from about 0.001 microgram / kilogram to about 10 milligrams / kilogram of animal body weight, preferably from 1 microgram / kilogram to about 6 microgram / kilogram of body weight. The preferred pharmacologically active agent is a pharmacologically active peptide, in particular calcitonin. A known class of pharmacologically active agents, calcitonins, have variable pharmaceutical utility, and are commonly employed in the treatment, for example, of Paget's disease, hypercalcemia, and post-menopausal osteoporosis. Calcitonins, for example, from salmon, eel calcitonin- (Asu1 -7) or human, are compounds that are long-chain polypeptide hormones secreted by parafollicular cells of the thyroid gland in mammals, and by the ultimobranchial gland of birds and fish. Different calcitonins, including salmon, pork, and eel calcitonins, are commercially available, and They are commonly used for the treatment, for example, of Paget's disease, malignancy, and osteoporosis. Calcitonin can be any calcitonin, including natural, synthetic or recombinant sources thereof, as well as calcitonin derivatives, such as eel calcitonin-1,7-Asu. The compositions may comprise a single calcitonin or any combination of two or more calcitonins. The preferred calcitonin is synthetic salmon calcitonin. Calcitonins are commercially available, or can be synthesized by known methods. The amount of pharmacologically active agent is in general an amount effective to carry out the intended purpose, for example, a therapeutically effective amount. However, the unit amount may be less than the dosage described when a plurality of the compositions are to be administered, i.e., the total effective amount may be administered in cumulative dosage units. The unit amount of active agent may also be greater than the effective amount when the composition provides a sustained release of the pharmacologically active agent. The total amount of active agent to be used can be determined by methods known to those skilled in the art. However, because the compositions can deliver the active agent more efficiently than the above compositions, smaller amounts of the active agent than those used can be administered. in unit dosage forms or in prior delivery systems to a subject, while still achieving the same blood levels and / or therapeutic effects. The appropriate dosage of calcitonin to be administered, of course, will vary depending, for example, on the amount of calcitonin to be administered, and on the severity of the condition being treated. However, satisfactory results will generally be obtained through intranasal or injectable systemic administration in daily dosages from about 0.5 micrograms / kilogram to about 10 micrograms / kilogram of animal body weight, preferably from 1 microgram / kilogram to about 6 micrograms / kilogram of body weight. Human growth hormone (hGH) (or somatotropic hormone or somatotropin) is a polypeptide hormone secreted by the anterior lobe of the pituitary gland that promotes the growth of the body, especially by stimulating the release of somatomedin, and which has an influence on the metabolism of proteins, carbohydrates, and lipids Under the definition of human growth hormone can also be included any of different natural or synthetic substances that regulate the growth of animals or plants, such as growth hormone of pituitary in vertebrates, and auxins in plants.
Bone Disorders Many types of bone disorders are known. A first class of disorders fall in the class that is related to disorders caused by bone resorption. Examples of these disorders are osteoporosis, osteolysis, and Paget's disease. In a second class of disorders are the arthritic conditions. An example of these disorders is osteoarthritis. New Formulations Many attempts have been made to promote the absorption of poly- (amino acids), such as peptides and proteins, for example hormones. In general it is believed that peptides and proteins need to be protected from the gastric and intestinal environment, where there are many peptidases and significant degradation can occur. It has been proven that the enteric coating and the addition of peptidase inhibitors to the pharmaceutical compositions are effective in improving the absorption of poly (amino acids), for example proteins and peptides, by oral administration. However, these approaches alone do not offer sufficient protection to achieve a satisfactory plasma level of the peptides and proteins, and there still remains a need to provide alternative means to successfully deliver the peptide and protein drugs to a patient, while protect from chemical and enzymatic degradation, in order to make it possible for them to provide a therapeutic effect.
This is in particular the case for calcitonins, wherein the preferred delivery route is oral administration, because it is convenient, relatively easy, and generally painless, which results in greater compliance of the patient relative to other modes of administration. supply. Brief Description of the Invention The present invention, therefore, provides a pharmaceutical composition that makes possible the successful delivery of drugs, in a pharmaceutically effective amount, in particular poly- (amino acids), such as peptides, peptidomimetics and proteins, by example, hormones, to a subject, by oral administration, to carry out the desired therapeutic effect. The present invention further provides an oral pharmaceutical composition comprising a poly- (amino acid) active ingredient, for example, a peptide or protein, wherein the disintegration time of the pharmaceutical composition and / or the rate of dissolution are rapid, such that the active ingredient is capable of achieving a therapeutic effect. In a particular aspect, the present invention provides pharmaceutical compositions comprising an active ingredient of peptide or protein, wherein the disintegration time of the pharmaceutical composition, for example the tablet, is up to ten minutes. The present invention also provides a composition pharmaceutical, for example, a tablet or capsule, which has a dissolution time of up to thirty minutes, for example up to twenty minutes, usually up to ten minutes. In particular, the present invention provides pharmaceutical compositions comprising a calcitonin as the active ingredient, together with the 5-CNAC delivery agent, wherein the pharmaceutical composition is manufactured in such a way that it provides a better oral bioavailability, for example, a bioavailability satisfactory or optimal oral for the active ingredient of calcitonin. By "bioavailability" is meant, within the scope of the present invention, the percentage of the dose that enters the systemic circulation after administration of a given dosage form. More explicitly, the ratio of the amount of drug "absorbed" from a test formulation to the amount of drug "absorbed" after administration of a conventional formulation. Frequently, the "conventional formulation" used in evaluating bioavailability is the aqueous solution of the drug, given intravenously. The amount of drug absorbed is taken as a measure of the ability of the formulation to deliver the drug to the sites of action of the drug; which depends on the disintegration and dissolution properties of the dosage form, and the rate of biotransformation in relation to the absorption rate. Dosage forms that contain identical amounts of active drug may differ markedly in its capabilities to make the drug available, and, consequently, in its capabilities to allow the drug to manifest its expected pharmacodynamic and therapeutic properties. It was within the scope of the present invention that it has been found in a surprising manner that the faster disintegration of the pharmaceutical compositions of the present invention in a subject, for example, in the stomach, provides the best absorption characteristics for the peptides and active proteins, where the greatest degradation of peptides or proteins occurs through pepsin or other enzymes. Therefore, the present invention further provides a pharmaceutical composition capable of delivering a peptide or protein by oral administration without the need for an enteric coating or a peptidase inhibitor. Accordingly, in the embodiments, the compositions of the invention are free of enteric coating or of peptidase inhibitors, or both.

Detailed Description of the Invention The present invention provides an oral pharmaceutical composition, which comprises an active ingredient of poly (amino acid), for example, a peptide or a protein, wherein the disintegration time of the pharmaceutical composition is such that the active ingredient is capable of achieving an adequate therapeutic effect. The present invention further provides an oral pharmaceutical composition, which comprises a poly- (amino acid) active ingredient, for example, a peptide or a protein, wherein the dissolution rate of the pharmaceutical composition is such that the active ingredient is capable of to achieve an adequate therapeutic effect. The present invention further provides an oral pharmaceutical composition, which comprises a poly- (amino acid) active ingredient, for example, a peptide or a protein, wherein both the disintegration time and the dissolution rate of the pharmaceutical composition are such that the active ingredient is capable of achieving an adequate therapeutic effect. Considering that the speed of degradation is very fast, that is, it occurs in milliseconds, it was believed that this rapid degradation can not be compensated by means of dissolution. However, surprisingly, it was found, within the scope of the present invention, that a sufficiently high therapeutic level of the active ingredient can be achieved in a relatively fast time frame, which is capable of compensating for biochemical degradation (e.g. , in the gastrointestinal tract) of the active ingredient.
As a result of the higher plasma concentration of the therapeutically active ingredients, it will be appreciated that the compositions of the present invention may not require that both active ingredient be present, compared to the compositions without the properties of the compositions described herein. Of course, this will not only have the benefit of reducing the production costs of the resulting medicinal products, but also reduces the risk of forming undesired, or even toxic, metabolites of the active ingredient in the patient. In addition, the compositions of the present invention can provide a method by which the therapeutic level of the active ingredient can be controlled, for example, the plasma concentration of an active ingredient. In other words, when there is a linear, or nearly linear, relationship between the disintegration, dissolution, and / or plasma concentration of an active ingredient, the desired plasma concentration can be determined in advance at any given time by the choice of a particular composition with a particular disintegration time and / or a particular dissolution time. For this purpose, the present invention also includes a library of compositions, each having different properties of disintegration and / or dissolution by the means described herein. A particular library of compositions comprises a library of tablets, each having a different hardness, for example, from 3 Kp to 20 Kp, in particular from 5 Kp to 20 Kp, more particularly from 5 Kp to 15 Kp, but especially from 5 Kp to 7 Kp. In a sub-library, each tablet of each hardness may also differ in the amount of active ingredient, vehicle, diluent, lubricant, skimmer, or disintegrant, for example. The present invention also includes a library of compositions, wherein the absence of lubricant can contribute to a faster establishment of disintegration and dissolution. In one aspect, the present invention provides an oral pharmaceutical composition having one or both of a dissolution time or a disintegration time of up to ten minutes. The present invention provides compositions for which the degree of dissolution is between 20 percent and 100 percent using the USP II paddle method in a dissolution medium of 0.1 N HCl and 0.01 percent Tween-80 during a prescribed period of time. In particular, the compositions of the invention have a degree of dissolution of between 20 percent and 100 percent, for example, 20 percent, 30 percent, 40 percent, 50 percent, 60 percent, 70 percent, 80 percent, 90 percent, and 100 percent, for a period of 0 to 60 minutes, for example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 , 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 55 and 60 minutes. In a preferred aspect of the present invention, the dissolution times and the degree of dissolution, as mentioned previously, they correlate with compositions having a disintegration time of less than ten minutes. In one embodiment of the invention, the composition has a disintegration time of not more than 10 minutes and a solution of > 80 percent in no more than 20 minutes, in particular, a disintegration time of no more than 6 minutes, and a dissolution of > 90 percent in no more than 20 minutes, particularly in the gastric environment. In yet another embodiment, the composition has a disintegration time of not more than 10 minutes and a solution of > 80 percent in 20 minutes, in particular a disintegration time of no more than 6 minutes and a dissolution of > 90 percent in 20 minutes, particularly in the gastric environment. The skilled person will be aware that a number of different parameters have an influence on the disintegration time or dissolution time of an oral solid phase formulation, including: • The dosage form (eg, capsule or tablet), • The identity of the active agent, • The identity of the additional ingredients, for example, the delivery agent, the disintegrant, the skimmer, the lubricant, the diluent, • The amounts (proportions) of the ingredients, • The particle sizes , · The hardness of the tablets.
Accordingly, it is not possible to stipulate a universal parameter set that defines all compositions that have a specified disintegration and / or dissolution time, but that exclude all other compositions. However, the skilled person has the appropriate knowledge and ability to make compositions having the dissolution time and disintegration time disclosed herein. For the avoidance of doubt, this descriptive memory includes guidance regarding the scope and measurement of disintegration time and dissolution time. The dissolution time of a compound can directly affect the plasma concentration of an active ingredient at any given time. Accordingly, the present invention includes a pharmaceutical composition in the solid phase, which comprises: a poly- (amino acid); a supply agent; and if necessary, a diluent; wherein the composition has a disintegration time of not more than 10 minutes. In particular, the present invention includes: a pharmaceutical composition for the oral delivery of poly (amino acids), which comprises: (i) a poly- (amino acid), (ii) a delivery agent, (iii) a diluent, wherein the composition has a dissolution time of not more than 10 minutes. The present invention also includes: a solid pharmaceutical composition for the oral delivery of poly (amino acids), which comprises: (i) a poly- (amino acid), (ii) a delivery agent, (ii) a disintegrant, (iv) a diluent, wherein the composition has a disintegration time of not more than 10 minutes. The solid composition can be in the form of a tablet. The tablet can be compressed in a manner as described herein. The poly- (amino acid) can be any poly- (amino acid) drug, for example, comprising a protein or a protein fragment. It can be any poly- (amino acid) described above under the heading "Background of the Invention". In a particular class of pharmaceutical compositions, the poly- (amino acid) is a hormone, for example a polypeptide hormone, such as a calcitonin, for example salmon calcitonin, a growth hormone, including human growth hormones (hGH), human growth hormones recombinants (rhGH), bovine growth hormones, and porcine growth hormones; growth hormone-releasing hormones, and a pituitary thyroid hormone, for example. The poly- (amino acid) is preferably a pharmaceutically active ingredient. Contrary to popular belief, it has surprisingly been found that the faster disintegration of the pharmaceutical compositions of the present invention in a subject, for example in the stomach, provides the best absorption characteristics for peptides and active proteins, in where the greatest degradation of peptides or proteins occurs through pepsin or other enzymes. A particularly preferred class of pharmaceutical compositions comprises salmon calcitonin as an active ingredient. The poly- (amino acid) may be in free or salt form. The poly (amino acid), such as, for example, calcitonin, may preferably be present in an amount of between 0.03 weight percent and 1 weight percent, in particular between 0.05 weight percent and 1 percent by weight, more particularly between 0.03 percent by weight and 0.5 percent by weight of the total mass of the pharmaceutical composition. In particular, the poly (amino acid), such as, for example, calcitonin, may be present in an amount of between 0.05 and 0.5 percent by weight, for example, between 0.1 and 0.2 percent by weight. weight. For ele, when the weight of the final pharmaceutical composition is 500 milligrams, this is equal to amounts of the poly- (amino acid), for ele calcitonin, from 0.25 milligrams to 5 milligrams. The delivery agent can be any suitable delivery agent for delivering poly (amino acids) by oral administration. The delivery agents useful in the formulation, for ele in the oral formulation, are any agents useful for delivering the particular pharmacologically active agent. Suitable delivery agents are any of the modified amino acids disclosed in the aforementioned U.S. Patent No. 5,866,536, or any of the modified amino acids described in the aforementioned US Patent No. 5,773,647. , or any combination thereof. The contents of the aforementioned Patents of the United States of North America Nos. 5,773,647 and 5,866,536 are hereby incorporated by reference in their entirety. In addition, the delivery agent may be the disodium salt of any of the aforementioned modified amino acids, as well as the ethanol solvates and hydrates thereof. Suitable compounds include the compounds of the following formula I: Formula I wherein: R1, R2, R3, and R4 are independently hydrogen, -OH, -NR6R7, halogen, alkyl of 1 to 4 carbon atoms, or alkoxy of 1 to 4 carbon atoms; R5 is an alkylene of 2 to 16 carbon atoms substituted or unsubstituted, alkenylene of 2 to 16 carbon atoms substituted or unsubstituted, alkyl of 1 to 12 carbon atoms- (arylene) substituted or unsubstituted, or aryl- (1-alkylene) to 12 carbon atoms) substituted or unsubstituted; and R6 and R7 are independently hydrogen, oxygen, or alkyl of 1 to 4 carbon atoms; and the alcohol hydrates and solvates thereof. The compounds of the formula I, as well as their disodium salts and the alcohol solvates and hydrates thereof, are described in International Publication Number WO 00/059863, together with the methods for their preparation. In addition, the delivery agent may be the disodium salt of any of the aforementioned modified amino acids, as well as the solvates of ethane and hydrates thereof.
The disodium salt can be prepared from the ethanol solvate, by evaporation or drying of the ethanol solvate, by methods known in the art to form the anhydrous disodium salt. The drying is generally carried out at a temperature of about 80 ° C to about 120 ° C, preferably about 85 ° C to about 90 ° C, and most preferably about 85 ° C. The drying step is generally carried out at a pressure of 26"Hg (66cmHg) or greater.The anhydrous disodium salt generally contains less than about 5 weight percent ethanol, and preferably less than about 2 weight percent. percent by weight of ethanol, based on 100 percent of the total weight of the anhydrous disodium salt The disodium salt of the delivery agent can also be prepared by making a paste of the delivery agent in water, and adding two molar equivalents of hydroxide of aqueous sodium, sodium alkoxide, or the like The suitable sodium alkoxide includes, but is not limited to, sodium methoxide, sodium ethoxide, and combinations thereof.An yet additional method for the preparation of the disodium salt is by the reaction of the delivery agent with a molar equivalent of sodium hydroxide, to provide the disodium salt.The disodium salt can be isolated as a solid by the concentration of the e contain the disodium salt until a thick paste is obtained by vacuum distillation. This paste can be dried in a vacuum oven to obtain the disodium salt of the Supply as a solid. The solid can also be isolated by spray drying an aqueous solution of the disodium salt. The delivery agents can be prepared by methods known in the art, for example as mentioned above, by the methods described in the Patents of the United States of North America Nos. 5,773,647 and 5,866,536. Ethanol solvates, as described in International Publication Number WO 00/059863, mentioned above, include, but are not limited to, a molecular or ionic complex of molecules or ions of ethanol solvent with molecules or ions of the disodium salt of the supply agent. Typically, the ethanol solvate contains about one molecule or ethanol ion per each disodium salt molecule of the delivery agent. The ethanol solvate of the disodium salt of the delivery agent can be prepared by dissolving the delivery agent in ethanol. Typically, each gram of the delivery agent is dissolved in from about 1 to about 50 milliliters of ethanol, and in general from about 2 to about 10 milliliters of ethanol. Then the supply agent / ethanol solution is reacted with a molar excess of a sodium-containing salt, such as a salt containing monosodium, in relation to the delivery agent, ie, for each mole of delivery agent, There is more than one mole of sodium cations, producing the ethanol solvate. Suitable monosodium salts include, but are not limited to, sodium hydroxide; sodium alkoxide, such as sodium methoxide and sodium ethoxide; and any combination of the above. Preferably, at least about two molar equivalents of the monosodium-containing salt are added to the ethanol solution, ie, for each mole of delivery agent, there are at least about two moles of sodium cations. Generally speaking, the reaction is carried out at or below the reflux temperature of the mixture, such as at room temperature. Then the ethanol solvate is recovered by methods known in the art, such as concentration of the resulting paste with atmospheric distillation, cooling of the concentrated paste, and filtration of the solid. The recovered solid can then be dried under vacuum to obtain the ethanol solvate. The hydrates of the disodium salts of the delivery agents can be prepared by drying the ethanol solvate from an anhydrous disodium salt, as described above, and hydrating the anhydrous disodium salt. Preferably, the monohydrate of the disodium salt is formed. Because the anhydrous disodium salt is very hydroscopic, the hydrate is formed after exposure to atmospheric moisture. In general, the hydration step is carried out from about room temperature to about 50 ° C, preferably from room temperature to about 30 ° C, and in an environment having a relative humidity of at least 50 ° C. hundred. In an alternative way, the anhydrous disodium salt can be hydrated with steam.
Preferred delivery agents can be selected from: N- (5-chloro-salicyloyl) -8-amino-caprylic acid (5-CNAC), N- (10- [2-hydroxy-benzoyl] -amino) -decanoic (SNAD), N- (8- [2-hydroxy-benzoyl] -amino) -caprylic acid (SNAC), and its mono- and di-salts, for example its monosodium and disodium salts, the ethanol solvates of their salts, and the monohydrates of their salts, and any combinations thereof, such as the ethanol solvates of their sodium salts and the monohydrates of their sodium salts, and any combinations thereof, for example. Other salts, such as potassium, lithium, and calcium are also contemplated. The agents of supply of 5-CNAC, SNAD, and SNAC are very soluble in water, especially in the alkaline conditions of the intestine, and are absorbed almost completely, ie, by more than 90 percent, in the gastrointestinal tract, such like the duodenum, for example, whether ingested in a micronized or coarse form. Conversely, the delivery agents can form precipitates in an acidic environment, for example in the stomach. Preferably, the delivery agent is in a micronized form. A particularly surprising aspect of the present invention is the effect that the selected delivery agent can have on the dissolution time of the active ingredient. For example, when the vehicle is 5-CNAC, the transformation of an insoluble form, for example the solid form of the sodium salt or the free acid of 5-CNAC in a particular environment, for example the intestinal environment, to a soluble form, for example the -CNAC in solution, provides a mechanism by which the active ingredient has a high rate of dissolution, for example, no more than ten minutes. Accordingly, it is hypothesized that any insoluble form of a delivery agent, which becomes a soluble entity after its contact with the gastrointestinal environment (such as that of the duodenum environment, for example), can provide a mechanism for a high dissolution speed of an active ingredient. Accordingly, the delivery agent, such as 5-CNAC for example, or its salts, can provide a satisfactory or optimum micro-environment for the satisfactory or optimum rate of dissolution and / or absorption of an active ingredient of poly ( amino acid). In particular, the disodium salt of 5-CNAC can provide a satisfactory or optimal micro-environment for the absorption of salmon calcitonin. The absorption of calcitonin and salmon can be measured by plasma concentration, for example. In a particularly preferred class of pharmaceutical compositions, the delivery agent is 5-CNAC. The 5-CNAC may be in free or salt form, or it may consist of a wide range of particle sizes, for example in the range of average particle sizes of 50 to 5 microns. Preferably, the delivery agent is in a micronized form.
The average particle size of the micronized delivery agent, for example 5-CNAC, can be measured by grinding the coarse 5-CNAC, and periodically sampling with measurements of reference particle sizes, to identify when the desired average particle size is reached. A process for micronizing 5-CNAC is described in International Publication Number WO 2005/014031, which is incorporated herein by reference; see in particular page 10 and example 1, which describe the effects of 5-CNAC particles of different sizes. The preferred delivery agent is present in an amount of between 5 percent by weight and 80 percent by weight, in particular between 10 percent by weight and 70 percent by weight, more particularly from 20 percent by weight and 60 percent by weight, still more particularly between 40 percent by weight and 60 percent by weight of the total mass of the pharmaceutical composition, eg, 50 percent by weight. When the weight of the final pharmaceutical composition is 500 milligrams, this equals amounts of 2.5 to 400 milligrams of the delivery agent present in the final pharmaceutical composition.
In addition, when the delivery agent is 5-CNAC or a salt thereof, its salt form is preferably present in an amount of more than 90 weight percent by the total weight of 5-CNAC present in the composition; this applies particularly when the disodium salt of 5-CNAC is present.
The preferred delivery agent is the disodium salt of 5-CNAC. The ratio of the active ingredient to the delivery agent is preferably between 1/25 and 1/400, in particular between 1/50 and 1/300, more particularly between 1/100 and 1/200, the most preferred proportion being the case of the sCT / 5-CNAC compositions of 0.5 mg'1 mg sCT for 200 milligrams to 300 milligrams of the disodium salt of 5-CNAC. The disintegrant may be selected from any super-disintegrant, for example, synthetic polymers capable of swelling through the absorption of water, of which mention may be made in particular of crospovidones and povidones. The most specific examples of the disintegrants are crospovidone, povidone, Explotab, or AC-Di-Sol. In a referred class of pharmaceutical compositions, the disintegrant is Crospovidone. Crospovidone is a synthetic cross-linked homopolymer of N-vinyl-2-pyrrolidone, also referred to as 1-ethenyl-2-pyrrolidinone, having a molecular weight of 1,000,000 or greater. The super-disintegrants are agents that can absorb water and swell to a significant degree, either by the wicking effect or by hydration. They are more efficient than the conventional disintegrant, due to their water absorption and their swelling capacity. Other agents that decrease the disintegration time by effervescent means and / or other means can also be used. The preferred disintegrant is present in an amount from 0.02 weight percent to 10 weight percent, in particular from 0.2 weight percent to 10 weight percent, more particularly from 1.0 weight percent to 8 weight percent, for example, 3 percent by weight at 7 percent by weight of the total mass of the pharmaceutical composition, for example 5 percent by weight. When the weight of the final pharmaceutical composition is 500 milligrams, this is equal to amounts of the disintegrant of between 0.1 milligrams and 50 milligrams. Commercially available crospovidones include Poliplasdone XL, Poliplasdone XL-10, Poliplasdone INF-10 available from ISP, Kollidon CL, available from BASF Corporation. The preferred crospovidone is Poliplasdone XL. L povidone is a synthetic polymer consisting of linear 1-vinyl-2-pyrrolidinone groups having a molecular weight of generally between 2,500 and 3,000,000. Commercially available povidones include Kollidon K-30, Kollidon K-90F available from BASF Corporation, and Plasdona K-30 and Plasdona K-29/32, available at ISP. In an alternative way, they can be synthesized by known processes. The diluent may be, for example, Avicel PH 102 or 101. The diluent may be present in the pharmaceutical composition up to 90 weight percent, based on the total composition, or it may be used to make any difference between the mass of the final desired and actual pharmaceutical composition, which may be, for example, up to 600 milligrams, for example 500 milligrams. Preferably, the binder is present in an amount of between and 70 percent by weight, based on the total composition, for example 40 to 60 percent by weight, for example 50 percent by weight. When the weight of the final pharmaceutical composition is 500 milligrams, this is equal to amounts, for example, from 100 milligrams to 350 milligrams. In a preferred embodiment of the present invention, the diluent is a microcrystalline cellulose. The addition of a diluent will decrease the disintegration times of a tablet. The dissolution times of an active agent may be independent of the diluent. The addition of a skimmer or lubricant to a tablet can increase the dissolution rate of an active ingredient, and this is known to the person skilled in the art, due to the hydrophobicity of the lubricant, ie, magnesium stearate, stearyl fumarate of sodium, calcium stearate, etc. Disintegration and Dissolution The terms "disintegration" and "dissolution" can be defined in the USP < 701 > and < 711 > , which are incorporated herein by reference. It should be understood that the "dissolution time", according to the present invention, is the time that is required for a given amount (or fraction) of a drug in a solution to be released from a solid dosage form. The dissolution time is measured in vitro, under conditions simulating those that are present in vivo, in experiments where the amount of drug in solution is determined as a function of time. For example, the solution can be determined by the USP XXIII Palette Method, using a USP dissolution test apparatus of 2 to 50 revolutions per minute. It should be understood that the "disintegration time" (DT) according to the present invention is the time it takes for the formulated drug product (i.e., a capsule or tablet) to decompose in the primary particles, under carefully specified test conditions. The conditions of the laboratory test, in vitro, are established to simulate those that occur in vivo. For example, when the composition is in the form of a tablet, the disintegration time is the time it takes for a tablet to break down into granules of a specified size. Factors such as the class and amount of tablet binders, and the degree of compression employed in the compaction of the tablet ingredients, determine the disintegration time. The disintegration time of the pharmaceutical composition according to the present invention is not greater than 10 minutes, for example, it may not be more than 9 minutes. Preferably, the disintegration time is up to 8 minutes, for example 6 minutes, for example it may be less than 8 minutes, as in the case of 7 minutes. In an additional class of pharmaceutical compositions, the disintegration time is up to 5 minutes for example between 1 and 4 minutes, such as 2 minutes, for example. In still a further class of pharmaceutical compositions, the disintegration times are less than two minutes, for example 1 minute or less. Accordingly, a further aspect of the present invention is that the compositions have a dissolution time of up to ten minutes. In summary, the disintegration times of the compositions of the present invention are any of 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 minutes or any fraction thereof, such as, for example, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 120, 130, 140, 150, 160, 170, 180 seconds, etc. Disintegration refers here to the physical process by which a tablet is broken down into fine particles, for example less than 0.065 centimeters in diameter. This process is monitored visually, and belongs to the physical integrity of the tablet alone. Typically, disintegration is carried out by monitoring the time it takes for 100 percent of the dispersed particles to pass through a coarse-mesh cylinder, eg, 7.75 centimeters long, with an internal diameter of 21.5 millimeters, and a wall of approximately 2 millimeters thick, in a water bath maintained at 37 ° C (+ 2 ° C), according to USP < 701 > . The disintegration time of a composition can be linked at the time of dissolution. The dissolution time is the time in which an active ingredient is dissolved in a liquid medium. The solution is monitored by means of UV or HPLC analysis, and provides the approximate time required for the complete release of a drug. The active ingredients in a disintegrated composition, such as, for example, a tablet, are not necessarily in solution and available for absorption. A long disintegration time is incompatible with the rapid absorption of the drug; a short disintegration time, by itself, does not ensure rapid absorption. Typically, there is some relationship between disintegration and dissolution. For the compositions of the present invention, a linear relationship could be established between the dissolution time and the disintegration time. In the current example, it could be shown that the shorter disintegration time corresponds to a faster dissolution, while the longer disintegration time is related to a slower dissolution. More specifically, a disintegration time of 6 minutes and less, corresponds to a dissolution of > 90 percent in 20 minutes, a disintegration time of 9 minutes corresponds to a dissolution of approximately 30 percent in 20 minutes. In a specific embodiment of the invention, the dissolution time of the compositions has a linear relationship with the dispersion time of the compositions. As such, in yet another As an aspect of the present invention, the disintegration time of the composition can be used to predict the dissolution time of the composition. Likewise, when the dissolution time of the composition is known, the disintegration time of the composition can be calculated. The use of the relationship between the disintegration time and the dissolution time is particularly effective when the composition is in a tablet form. Here, the disintegration time will be the disintegration time of the tablet in the stomach. Accordingly, factors that have an effect on the disintegration time of the tablet, for example the hardness of the tablet, can also be used to predict the dissolution time of an active ingredient. The degree of dissolution can be reflected in the degree of absorption. Accordingly, a successful dissolution parameter is one in which a therapeutically effective amount of the active substance or substances reaches the blood plasma. In a monkey pharmacokinetic study, a formulation containing 0.8 milligram of calcitonin should provide a peak plasma concentration (Cmax) of not less than 400 picograms / milliliter, and / or a reduction in plasma calcium level of > 20 percent in 6 hours. Accordingly, it is contemplated that, by adjusting the disintegration time of the compositions of the invention, the speed and / or amount of absorption can be optimized and / or change as required. As an example, when the composition is in the form of a tablet, the bioavailability can be adjusted by adjusting the hardness of the tablet, for example. As such, the ingredients (excipients / vehicles) of a tablet, and the degree of compression in tablet formation, can influence the bioavailability of an active ingredient in a composition of the present invention. In yet another class of compounds according to the present invention, the pharmaceutical composition is in the form of a compressed tablet. In this form, the tablet preferably has a hardness of between 5 and 10 kilopascals. In this class of compounds, the hardness of the tablet can be used to further determine the disintegration time of the pharmaceutical composition. The present inventors have found that, using the same pharmaceutical composition, the hardness of the tablet has a linear relationship with the disintegration time. ThereforeIt is another aspect of the present invention that the disintegration time of the pharmaceutical composition depends on the hardness of the tablet. More specifically, a certain disintegration time can be achieved by controlling the hardness of the compressed tablets. Tablet Hardness A tablet of a preferred dough with the preferred formulation having a hardness of between 5 and 20 Kp would typically have a disintegration time of less than 6 minutes.
The hardness of a tablet is directly related to the disintegration time of the tablet, as shown in the following Tables 1 and 2, and in Figures 3 and 4. Table 1 Table 2 Where: RSD is the relative standard deviation; and DT is the time of disintegration. Accordingly, the compression force applied to a particular composition when a tablet is manufactured, can determine the disintegration time of the pharmaceutical composition. Additional Ingredients In the additional classes of compositions, the pharmaceutical composition additionally comprises a skimmer and / or a stabilizer and / or a dry binder. Therefore, in a class of pharmaceutical compositions, the pharmaceutical composition comprises a further skim agent. The skid agent is, for example, cab-o-sil. The skimmer may be present in an amount of up to 1.5 weight percent, for example 0.02 to 0.5 weight percent, based on the total composition, for example, 0.3 weight percent. When the weight of the final pharmaceutical composition is 500 milligrams, this is equal to amounts of up to 7.5 milligrams. In a further class of pharmaceutical compositions, the pharmaceutical composition additionally comprises a lubricant. The lubricant is, for example, magnesium stearate. The lubricant may be present in an amount, for example, 0.5 to 1.5 percent by weight, based on the total composition, for example from 0.75 to 1.25 weight percent, for example, of 1 weight percent. When the weight of the final pharmaceutical composition is 500 milligrams, this equals amounts of 2.5 milligram to 7.5 milligrams. In addition to the specific ingredients mentioned herein, the compositions of the present invention, which have the disintegration and / or dissolution properties mentioned herein, may also be combined with other technologies, such as those described in Patent Numbers WO 94/26778; US 5,359,030; US 5,438,040; US 5,681,811; US 6,191,105; US 6,309,633; US 6,380,405; US 6,436,990; US 6,458,776; WO 97/33531; US 5,912,014; US 608,618 and US 6,479,692 (the content thereof is hereby incorporated by reference in its entirety).

EXAMPLES The following examples serve to further illustrate the invention, and will be readily understood by one of ordinary skill in the art. The examples are not intended to be limiting of the present invention in any way.
EXAMPLE 1: Pharmaceutical Composition 1 Ingredient Quantity (mg) Percentage Calcitonin salmon 0.8 0.16 5-CNAC micronized 228 45.6 Avicel PH 102 (E) 241 47.94 Crospovidone, NF 25 5 Magnesium stearate 5 0.3 Total 500 Calcitonin from salmon, 5-CNAC, and crospovidone were mixed together in a first step of mixing. The Avicel PH 102 was sieved, and added to the mixture, and mixed in a second mixing step. Magnesium stearate was then added, and the mixture was further combined in a final mixing step. The final mixture was compressed into a 500-milligram tablet, and evaluated in a Rhesus monkey. The results are shown in Figure 5.
EXAMPLE 2: Alternative Pharmaceutical Composition (3 Lots) The same composition as in Example 1 was made, that is, composition comprising: Ingredient Quantity (mg) Percentage Calcitonin of salmon 0.8 0.16 5-CNAC micronized 228 45.6 Avicel PH 102 (E) 241 47.94 Crospovidone, NF 25 5 Magnesium stearate 5 0.3 However, in contrast to Example 1, salmon Calcitonin and Avicel PH 102 were mixed in a first mixing step. Then 5-CNAC and crospovidone were added to the first mixture, in a second mixing step. Finally, the magnesium stearate was added in a final mixing step. Then the final mixture was compressed into 3 different compression levels, to obtain 3 different batches of tablets, each having a different hardness, in order to provide 3 different disintegration times: (i) Disintegration time of 1 minute 10 seconds . (ii) Disintegration time of 5 minutes 40 seconds. (iii) Disintegration time of 8 minutes 51 seconds.
