  • Patent number: 10004693
    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).

  • Patent number: 8821935
    Abstract: The present invention is directed to microcapsules for reliably modified release and adapted to industrial reproduction of an active principle hardly water-soluble, other than anti-hyperglycemia agents. Each of said microcapsules comprises a core of hardly soluble active principle and a coating film applied on the core. Their mean diameter is less than 1000 microns. The coating film contains a film-forming polymer (PI) insoluble in gastrointestinal tract fluids, a water-soluble polymer (P2), a plasticizer (PL), and optionally a lubricating surfactant (TA). Said coating film represents at least 4% p/p of dry matter of their total weight, and its components P1, P2, PL satisfy the following characteristics: dry weight mass fraction of PI relative to the total coating weight ranging between 40 and 90%; dry matter weight fraction of PL/P1+P2 ranging between 15 and 60%; dry matter weight fraction of PL/P1+P2 ranging between 1 and 30%.

  • Patent number: 8734850
    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.

  • Patent number: 8652523
    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).

  • Patent number: 8197850
    Abstract: The invention concerns an oral galenic form for prolonged release of anti-hyperglycaemic (metformin) active principles. Said medicine enables to obtain an efficient therapeutic protection over 24 hours by overcoming the problems of bypass of the absorption window and the massive localised release of active principles. Therefor, said medicine comprises several thousand anti-hyperglycaemic (metformin) microcapsules each consisting of a core comprising at least an anti-hyperglycaemic agent and of a coating film applied on the core and enabling the prolonged release in vivo of the anti-hyperglycaemic agent. Said microcapsules have a grain size distribution ranging between 50 and 100 microns. The reproducibility of the transit kinetics and hence of bioavailability are very high. There results for the patient a lesser risk of hyperglycaemic or hypoglycaemic. The invention also concerns the preparation of said medicine and the use of a plurality of said microcapsules for making an anti-hyperglycaemic medicine.

  • Patent number: 8101209
    Abstract: The invention relates to a microparticulate system for the delayed and controlled release of active principles (AP) whose absorption window in vivo is essentially limited to the upper parts of the gastrointestinal tract, this system being intended for oral administration. The object of the invention is to provide a system ensuring that the AP is released with certainty by means of a dual mechanism of “time-dependent” and “pH-dependent” release. To achieve this object, the invention proposes a multimicrocapsular oral galenical form which is designed so as to guarantee therapeutic efficacy, and in which the release of the AP is governed by a dual release triggering mechanism that is “time-triggering” and “pH-triggering”. This system comprises of microcapsules (200 to 600 ?m) comprising a core of AP coated with a film (maximum 40% by weight) comprising a hydrophilic polymer A (Eudragit® L) and a hydrophobic compound B (vegetable wax, melting point=40-90° C.), B/A being between 0.2 and 1.5.

  • Publication number: 20110129539
    Abstract: The invention concerns liquid pharmaceutical formulations, for oral delivery, with modified release of amoxicillin and consisting of suspensions of coated particles of amoxicillin (microcapsules). The microcapsules constituting the dispersed phase of the suspension are designed, according to the invention, to enable modified release of amoxicillin, 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 amoxicillin, said liquid phase being furthermore saturated with amoxicillin.
