Abstract

Procédé par voie humide utilisé pour préparer une composition pharmaceutique solide destinée à l'administration par voie orale de médicaments à faible dosage dont les principes actifs présentent des structures stéroïdiennes ou de type stéroïdien. Ce procédé consiste à mettre en suspension des médicaments ayant une faible solubilité, dans une solution aqueuse de liant contenant des traces d'un tensioactif. On mélange ensuite cette suspension aqueuse à des charges de remplissage et on les met sous forme de granules. Les granules déshydratés peuvent être ensuite transformés en capsules, comprimés, pastilles, tablettes, produits ou suspensions à libération prolongée ou retardée.
