摘要： The invention relates to novel materials based on biodegradable polyamino acids that are useful for vectorizing active principle(s)(AP). The aim of the invention is to supply a new polymeric raw material that is used for vectorizing AP and optimally fulfills all requirements concerning biocompatibility, biodegradability, the ability to be easily associated with numerous active principles or solubilize the active principles and to release the active principles in vivo. Such polymers can also be readily and economically transformed into particles vectorizing active principles according to the grafting rate of the hydrophobic groups, said particles being able to form stable aqueous colloidal suspensions. The aim of the invention is achieved by the inventive amphiphile polyamino acids comprising aspartic and/or glutamic units that carry grafts which encompass at least one hydrophobic unit and are linked to the aspartic and/or glutamic units via a rotula containing two amide functions, more particularly via a spacer of the lysine or ornithine type. The amide functions ensure better stability during hydrolysis than comparable products known in prior art. The invention also relates to new pharmaceutical, cosmetic, dietetic, or phytosanitary compositions based on the inventive polyamino acids.

The delivery particles are based on a three-block copolymer: polyethylene glycol/hydrophilic polyaminoacid/hydrophobic polyaminoacid. These three-block copolymers can be associated with an active principle without denaturing it, and perform a controlled and long-term release of the active principle in vivo, and thus provide the active principle with a very prolonged release. Also disclosed is a powder form solid from which are derived the delivery particles, the preparation of the powder-form solid, a suspension of delivery particles based on the three-block copolymer, and pharmaceutical specialties obtainable from the delivery particles filled with active principle.

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 comprises 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.

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.
