Abstract:
The present invention relates to solid microparticulate oral pharmaceutical forms whose composition and structure make it possible to avoid misuse of the pharmaceutical active principle (AP) they contain.The object of the present invention is to prevent solid oral drugs from being misappropriated for any use other than the therapeutic use(s) officially approved by the competent public health authorities. In other words, the object is to avoid the voluntary or involuntary misuse of solid oral drugs.The invention relates to a solid oral pharmaceutical form which is characterized in that it contains anti-misuse means, in that at least part of the AP it comprises is contained in coated microparticles for modified release of the AP, and in that the coated microparticles of AP have a coating layer (Ra) which assures the modified release of the AP and simultaneously imparts crushing resistance to the coated microparticles of AP so as to avoid misuse.
Abstract:
The invention relates to liquid pharmaceutical formulations for oral administration with the modified release of active principle(s), excluding amoxicillin, said formulations consisting of suspensions of coated particles of active principles (microcapsules). According to the invention, the microcapsules constituting the disperse phase of the suspension are designed to allow the modified release of the active principle(s) according to a profile that does not change during the storage of the liquid suspension. To do this the inventors propose the selection of a specific coating composition for the microcapsules which consists of at least four components that allow these microcapsules to be stored in water without modifying their properties of modified release of the active principle, this liquid phase furthermore being saturated with active principle(s).
Abstract:
The invention relates to oral pharmaceutical compositions for the prevention and/or the treatment of viral diseases. This invention also addresses methods of prevention and/or treatment of these viral diseases, using these oral compositions. One of the main problems considered in the present invention is to enhance the efficiency of anti-viral treatments, especially against Hepatitis C virus by means of ribavirin, for example in combination with interferon. The oral ribavirin antiviral composition according to the invention increases the bio-absorption time of ribavirin, and thus improves the treatment of patients. Said composition comprises at least one modified release form of ribavirin, the bio-absorption time BAT of which is greater than the bio-absorption time BAT* of a reference* immediate release form of ribavirin administered at the same dose; BAT being preferably comprised between 2 and 15 h and more preferably between 4 and 12 h. Said composition is a reservoir type form or a matrix type form. Said composition is a gastric retentive system or a multiparticulate form.

The invention relates to liquid pharmaceutical formulations for oral administration with the modified release of amoxicillin, said formulations consisting of suspensions of coated particles of amoxicillin (microcapsules). According to the invention, the microcapsules constituting the disperse phase of the suspension are designed to allow the modified release of the amoxicillin according to a profile that does not change during the storage of the liquid suspension. To do this the inventors propose the selection of a specific coating composition for the microcapsules which consists of at least four components that allow these microcapsules to be stored in water without modifying their properties of modified release of the amoxicillin, this liquid phase furthermore being saturated with amoxicillin.
Abstract:
Modified-release multimicroparticulate pharmaceutical form capable of maintaining the modified release of the active principle in an alcoholic solution and of resisting attempts at misuse.
Abstract:
An oral solid dosage form containing one or several active principle(s) having analgesic properties, the composition of said dosage form being such that it prevents the misuse of said dosage form through the liquid extraction of the active principle(s) contained therein, using commonly available solvents.Said oral solid dosage form containing at least one salt of at least one analgesic active principle, and an anti-misuse system comprising at least one quenching agent, said quenching agent being suitable for inducing complexation of said analgesic active principle salt when the analgesic active principle salt is improperly extracted, notably by a drug abuser, in vitro in solution from said oral solid dosage form.
Abstract:
The field of the invention is that of oral pharmaceutical medicinal products or compositions, more particularly of the type of those comprising one or more active principles.The aim of the invention is to provide an improved oral medicinal product that can be administered in one or more daily doses, with modified release of active principle (in particular an active principle), for improving the prophylactic and therapeutic efficacy of such a medicinal product.This aim is achieved by means of the multimicrocapsular oral pharmaceutical form according to the invention in which the release of the AP is controlled by means of a double mechanism of triggering the release: “time triggering” and “pH triggering”. This medicinal product comprises microcapsules with modified release of active principle, each containing a core comprising the active principle and one or more swelling agents, and at least one coating making possible the modified release of the active principle.

Abstract:
The invention relates to pharmaceutical compositions of acetylsalicylic acid-based microcapsules to selectively inhibit the COX in the portal vein and/or in the liver to reduce the production of thromboxane. Further, the pharmaceutical composition minimizes COX inhibition in the systemic circulation to optimize the inhibition of platelet aggregation. Certain embodiments also address methods of prevention and/or treatment of these diseases, using these oral compositions such as enhancing the safety of antithrombotic treatments. Other embodiments contemplate oral pharmaceutical compositions that combine acetylsalicylic acid with anti-platelet aggregation drugs, without inducing gastric side effects.
