Abstract

L'invention se rapporte au domaine de la chimie thérapeutique et, en particulier, à celui de la pharmacotechnie. Elle a plus particulièrement pour objet des dispersions solides d'agents médicamenteux dans un agent transporteur hydrophile, caractérisées en ce que le principe actif est dissout dans un solvant organique volatil contenant un amide cyclique très hydrophile et en ce que la solution organique est pulvérisée et séchée en un coprécipité qui est broyé, tamisé et dilué avec un excipient ou un véhicule pharmaceutiquement-acceptable. Le coprécipité sert de matière première pour la réalisation de médicaments.The invention relates to the field of therapeutic chemistry and, in particular, to that of pharmacotechnology. It relates more particularly to solid dispersions of medicinal agents in a hydrophilic transport agent, characterized in that the active principle is dissolved in a volatile organic solvent containing a very hydrophilic cyclic amide and in that the organic solution is sprayed and dried into a co-precipitate which is ground, sieved and diluted with a pharmaceutically acceptable excipient or vehicle. The coprecipitate serves as a raw material for the production of medicaments.
