Patent

CA 2287485

The invention concerns the field of therapeutic or food chemistry, and more particularly the production of novel galenic forms. It concerns a novel method for obtaining microspheres with predetermined particle size distribution, containing an active principle using a matrix-forming agent made of a hydroalkane solution in the presence of a surfactant, to form an O/W emulsion of said matrix-forming agent, which consists in allowing the alkanol from the emulsion droplets to be diffused towards the continuous phase, so as to form in the droplet a coprecipitate of matrix-forming agent and active principle, in separating the microspheres, in washing and drying them to collect solid or hollow microspheres. The invention is useful in therapy, for dyes, in the food industry and as flavouring agents.

La présente invention s'adresse au domaine de la chimie thérapeutique ou alimentaire, et plus spécialement à la réalisation de nouvelles formes galéniques. Elle a pour objet un nouveau procédé d'obtention de microsphères de distribution granulométriques déterminée, contenant un principe actif en utilisant un agent matriciel en solution hydroalkanolique en présence d'un agent tensioactif, pour former une émulsion O/W de cet agent matriciel, qui consiste à laisser diffuser l'alkanol des gouttelettes d'émulsion vers la phase continue, de manière à former dans la gouttelette un coprécipité d'agent matriciel et de principe actif, à séparer les microsphères, à les laver et à les sécher de manière à recueillir des microsphères pleines ou creuses. Utilisation dans le domaine de la thérapeutique, des colorants, des aliments et des agents d'aromatisation.
