摘要： The invention concerns a galenic system with prolonged/controlled release of the medicinal and/or nutritional active principle, for oral administration. The aim is to provide a system enabling to obtain with one single tolerable and acceptable dose of active principle, efficient therapeutic protection over 24 hours (increasing the bioabsorption time without affecting bioavailability). To achieve this, the invention provides a composition comprising two controlled release systems associated in series, namely: individualised coated particles (microcapsules) of active principle forming an internal phase, the coating comprising a film-forming polymer P1 (ethylcellulose), a nitrogenous polymer (polyvinylpyrrolidone), a softener (castor oil) and a lubricant (magnesium stearate), and an external phase of functional carriers: polyelectrolytic hydrophilic polymer: (alginate), neutral hydrophilic polymer (hydroxypropylmethylcellulose) and a gelling additive (calcium acetate), said composition spontaneously forming in the presence of water, a cohesive and stable composite macroscopic solid, wherein the external continuous phase is a gelled matrix including the active principle microcapsules. The invention is useful for delayed oral galenic formulation of metformin.

摘要： 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.

摘要： 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 consists of microcapsules (200 to 600 μm) 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. These microcapsules have a dissolution behavior in vitro such that, at a constant pH of 1.4, a latency phase of between 1 and 5 hours is observed, followed by a release of the AP, and such that the change from pH 1.4 to pH 6.8 results in a release of the AP without a latency period in vitro.
