摘要:
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.

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.

The invention relates to oral antibiotic drugs. The object of the invention is to limit or even stop the increase in antibiotic resistance without sacrificing the requirements of (a) increased efficacy of oral antibiotics, particularly for pediatric applications, (b) tolerance, (c) broad spectra of activity, and (d) good patient compliance. This object is achieved by the invention, which proposes the use of modified-release microcapsules, comprising a core that contains at least one active principle AP1 formed of at least one antibiotic, and a coating for said core that governs the modified release of said active principle, for the manufacture of a drinkable or orally dispersible antibiotic pharmaceutical formulation that makes it possible to limit the increase in the antibiotic resistance of the target germs, this formulation being: capable of administration in one or two, preferably two, intakes per day, and definable as follows, relative to an immediate-release oral formulation (IRF*) comprising at least one active principle API, and for the same dose D of API as IRF*: Tmic>T*micof IRF*

The invention concerns microcapsules with prolonged release of active principles with low solubility, consisting of a core containing the active principle and coated with a polymer layer which controls the release of the active principle. The aim is that said oral microcapsules containing hardly soluble active principles should have a coating film of sufficient thickness to ensure controlled permeability and should be adapted to industrial reproduction. This is achieved by the inventive microcapsules of mean diameter less than 1000 microns, and whereof the coating film contains a film-forming polymer (P1) insoluble in gastrointestinal tract fluids, a water-soluble polymer (P2), a plasticizer (PL), and optionally a lubricating surfactant (TA). Said microcapsules are characterized in that their coating films represents at least 3% p/p of dry matter, relative to their total weight and their core contains a hardly soluble active principle and a solubilizing agent (polyoxyethylene hydrogenated castor oil) which provides the core wherein it is contained with properties such that the behaviour of the exposed core (non-coated) in a given dissolving test (TD), is as follows: release of 80% of active principle in less than two hours. The invention also concerns the use of such microcapsules in galenic formulation.

The invention concerns microparticulate systems with modified release of oral active principle(s). The invention aims at providing a novel pharmaceutical with time-dependent and pH-dependent release mechanism, enabling: a) the latent period preceding the release of the active principle in the stomach; b) the pH triggering the release of the active principle in the intestine; c) the release speed of the active principle. This is achieved through the use of coated microparticles made from particles of active principle each coated with two coating films A and B. A comprises: film-forming (co)polymer (A1) insoluble in fluids of the gastrointestinal tract; ethylcellulose (co)polymer (A2) soluble in fluids of the gastrointestinal tract; plasticizing polyvinylpyrrolidone (A3); castor oil/optionally a surfactant and/or magnesium stearate lubricant (A4). B comprises a hydrophilic polymer (B1) bearing ionized groups with neutral pH (EUDRAGIT® L100-55) and a hydrophobic compound (B2) (LUBRITAB®). The invention also concerns medicines based on said microparticles.

The field of the present invention is that of oral pharmaceutical forms of losartan, and also treatments and administration methods relating thereto.The invention relates to the use, in an oral pharmaceutical form comprising losartan, of a coating or matrix including said losartan and allowing controlled release of said losartan, such that this form orally administered to a sample of individuals leads, irrespective of the fed or fasted state of the individuals, to a reduction of the interindividual standard deviation of the Cmax, which ensures lower variability of the efficacy and of the therapeutic safety of the pharmaceutical form relative to an immediate-release pharmaceutical form of losartan administered to this same sample of individuals, at the same dose.Another aim of the invention is to provide an oral pharmaceutical form of losartan that can be administered once a day and that is just as effective as the “one dose intake per day” forms and the “two dose intakes per day” forms.The invention is thus a modified-release oral pharmaceutical form of losartan comprising a plurality of losartan microunits (mean diameter: 50-1000 μm) making it possible to obtain, after a dose intake, a plasmatic profile of the type shown in FIG. 10.

The field of the invention is that of oral medicaments or pharmaceutical compositions, in particular of the type including one or more active principles. The aim of the invention is to provide an improved oral medicament to be administered in one or several daily doses and enabling the modified release of active principles (in particular of one active principle), whereby the prophylactic and therapeutic effectiveness of said medicament is improved. This aim is achieved by the oral multimicrocapsule galenic form according to the invention, in which the active principle release is controlled by a dual release trigger mechanism: “time-dependent trigger” and “pH-dependent trigger”. Said medicament includes microcapsules providing the modified release of the active principle, each comprising a core containing
