Abstract
Les systèmes liquisolides consistent en des formes pulvérulentes d'une fluidité et d'une compressibilité acceptables de médicaments liquides. Selon le concept des systèmes liquisolides, des médicaments lipophiles liquides ou des médicaments hydro-insolubles, dissous dans des solvants non volatils appropriés, peuvent être convertis en poudres coulantes et facilement compressibles, par simple mélange avec des excipients en poudre sélectionnés appelés matières de support et matières d'enrobage. On peut faire un croquis schématique des différentes étapes du procédé. Plusieurs catégories de cellulose microcristalline ou amorphe peuvent être utilisées comme matière de support, tandis que des poudres de silice à particules très fines peuvent être utilisées comme matière d'enrobage. En se fondant sur la théorie selon laquelle les matières de support et d'enrobage ne peuvent retenir qu'une certaine quantité de liquide tout en conservant en même temps une compressibilité et une fluidité acceptables, on a mis au point un nouveau modèle mathématique de formulation permettant de calculer les quantités maximales de matières de support et d'enrobage nécessaires pour produire des mélanges liquide/poudre d'une fluidité et d'une compressibilité acceptables.
