Definitions
- the present invention relates to pharmaceutical compositions with gastric residence comprising an active principle of the family of benzamides.
- Benzamides are chemical compounds whose structure includes the following motif:
- benzamides are useful as an active ingredient in medicaments intended for the treatment, in particular, of disorders of the central nervous system.
- Such benzamides may consist of amisulpride, tiapride, sulpiride, their salts, if any, their enantiomers and the salts of these enantiomers, as well as some of their derivatives.
- benzamides can be administered orally.
- bioavailability is understood here to mean the fraction of the active principle which is absorbed from its pharmaceutical form and which reaches the plasma.
- Low or irregular bioavailability can be the result of several factors, among which we can cite: low solubility or very slow dissolution of the active principle or of the dosage form which contains it; instability of the active ingredient, either over the entire length of the gastrointestinal tract, or in only one of its parts; the enzymatic degradation in the mucosa or in the liver of the active ingredient; slow or incomplete absorption of the active ingredient due to slow passive diffusion through the intestine or, in the case of an active mechanism, saturation of the transport system. It is known that the bioavailability of certain active ingredients can be modified by means of a sustained-release formulation which releases the active ingredient over the entire length of the gastrointestinal tract.
- the Applicant then considered improving the bioavailability of benzamides by formulating them in the form of a pharmaceutical composition with gastric residence promoting absorption in the small intestine, or even, more specifically, the upper parts of the small intestine.
- the invention thus consists of a pharmaceutical composition with gastric residence, characterized in that it comprises:
- (c) means allowing partial retention of the carbon dioxide generated by said carbon dioxide generating system.
- the figure represents the plasma release profile, in humans, of tiapride hydrochloride, this profile being obtained with a pharmaceutical composition according to the invention.
- the term "benzamide" within the meaning of the present invention, and unless otherwise indicated, covers the various enantiomers or diastereoisomers of these compounds, including their mixtures, in particular their racemic mixtures.
- a pharmaceutical composition with gastric residence is intended to reside for more than one hour in the stomach with a view to a prolonged and / or controlled release of the active principle.
- a pharmaceutical composition with gastric residence according to the invention has the advantage of being able to float on the surface of the liquids contained in the stomach, and this very quickly after having been absorbed. It has thus been found that a composition according to the invention can float for less than two minutes after being brought into contact with an aqueous liquid.
- the invention is more particularly suitable for the active principles consisting of sulpiride, 1 amisulpride, their salts, their enantiomers and the salts of these enantiomers, as well as tiapride, its oxide and its salts.
- Sulpiride is a neuroleptic useful in the treatment of acute and chronic psychoses (i) with a dehinibitating dosage: psychoses where predominantly withdrawal states, apragmatism, abuli or (ii) with dosage antiproductive: delusional or confusing psychoses, schizophrenia.
- Tiapride in particular in the form of hydrochloride, is a neuroleptic useful in the treatment of agitation and aggressiveness of the demented subject, behavioral disorders when they are manifested by phenomena of hyperactivity, aggressiveness, d irritability, especially in alcohol and the elderly, motor behavior disorders such as, for example, tremors, spontaneous or iatrogenic neuromuscular dyskinesia, abnormal movements such as chorea, tics, hemiballism, sensory behavior disorders such as for example headaches, migraines, various pain, especially intense and rebellious pain.
- the present invention is more particularly suitable for tiapride hydrochloride.
- Amisulpride or 4-amino-N [(1-ethyl-2-pyrrolidinyl) methyl] -5- (ethylsulfonyl) -2-methoxybenzamide, its enantiomers and some of its derivatives are described in French Patent No. 78,01632, the teaching of which is fully incorporated in this description.
- the invention is particularly suitable for amisulpride per se, ie 4 -amino-N- [(1-ethylpyrrolidin-2-yl) methyl] -5- (ethylsulfonyl) - 2-methoxybenzamide, its enantiomers levogyre
- a preferred tartrate consists of the compound described in Example IV of patent FR 78 01632, that is to say the (D) -tartrate of (S) - (-) - amisulpride, in other words the [S- (R * , R *)] -2, 3-dihydroxybutanedioate du (S) - (-) -4-amino- N- [(1-ethylpyrrolidin-2-yl) methyl] -5- (ethylsulfonyl) -2- methoxybenzamide.
- Amisulpride is a neuroleptic used in the treatment of psychosis, more particularly in the treatment of paranoid and productive schizophrenia, acute delusional psychosis, as well as in the treatment of deficit states of schizophrenia, residual psychotic changes and states of inhibition with slowdown. Amisulpride is also useful in the treatment of dysthymia.
- benzamides can be used in the context of the present invention such as metoclopramide, veralipride, alizapride or clebopride.
- the main function of the carbon dioxide generating system is to form carbon dioxide in the form of bubbles. These bubbles contribute to quickly bringing, then to maintaining the pharmaceutical composition of the invention on the surface of the liquids contained in the stomach.
- a carbon dioxide generating system suitable in a pharmaceutical composition according to the invention generally comprises at least one carbon dioxide generating agent.

Mention may more particularly be made, as acid compounds, of tartaric, maleic, malonic, malic, fumaric, succinic, adipic, citric acids and their partial salts, such as monosodium citrate.
- the acid compound content is generally chosen so that the number of moles in said acid compound relative to the number of moles in said carbon dioxide generating agent is between 0.7 and 1.4 times the stoichiometry.
- the active principle or any other component used in the formulation of the composition according to the invention has a basic character, it may be necessary to increase the content of acidic compound accordingly.
- the means allowing the partial retention of the carbon dioxide generated by the carbon dioxide generating system must allow the diffusion of the carbon dioxide in a controlled manner. It must prevent the too rapid diffusion of carbon dioxide which would lead to too short a flotation in time of the pharmaceutical composition according to the present invention. Conversely, it must allow sufficient diffusion of carbon dioxide to ensure a determined flotation time of said composition in the stomach, as well as sufficient diffusion of water or an aqueous compound within the composition according to the invention.
- This means can consist of a porous mineral matrix, in particular matrices based on silicates or calcium fluoride, or, preferably, in a polymer.
- said polymer consists of at least one hydrophilic polymer.
- the hydrophilic polymers suitable for a pharmaceutical composition according to the invention are those which can form a hydrocolloid gel in contact with an aqueous liquid, in particular the aqueous liquids contained in the stomach.
