  • Publication number: 20100068291
    Abstract: The invention relates to oral medicaments having a modified release of proton pump inhibitors (PPI's) that are, in particular, useful in preventing and treating gastrointestinal disorders. The aim of the invention is to provide a novel oral medicament based on PPI's ideally having all or some of the following characteristics: a) quickly providing relief to the patient by increasing the gastric pH after oral administration of the medicament; b) accelerating the recovery of patients while maintaining this increase in the gastric pH for as long as possible after oral administration of the medicament and, in particular, during the night; c) improving the observance of the treatment and the comfort of the patient by taking the medicament once daily.

  • Publication number: 20090220611
    Abstract: 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®).

  • Publication number: 20090123536
    Abstract: 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.

  • Publication number: 20080305160
    Abstract: 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”.

  • Publication number: 20070173464
    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.

  • Publication number: 20060165809
    Abstract: 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).

  • Publication number: 20060165807
    Abstract: The invention concerns liquid pharmaceutical formulations, for oral delivery, with modified release of active principle(s) excluding amoxicillin and consisting of suspensions of coated particles of active principles (microcapsules). The microcapsules constituting the dispersed phase of the suspension are designed, according to the invention, to enable modified release of the active principle(s), in accordance with a profile which remains unaltered during the shelf life of the liquid suspension. Therefor, the invention consists in selecting a coating composition specific to the microcapsules consisting of at least four components enabling preservation of said microcapsules in water without altering their properties of modified release of the active principle, said liquid phase being furthermore saturated with active principle(s).

  • Publication number: 20060110463
    Abstract: 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.

  • Publication number: 20050196459
    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.
