Sub-micron and micron-size stable particles of water-insoluble or poorly soluble drugs or other industrially useful insoluble compounds suspended in an aqueous medium containing at least one surface modifier are prepared by selecting the surface modifier or modifiers such that the hydrophile-lipophile balance (HLB) of the composition, defined as formula (I): is between 4 and 9. This provides a reliable HLB-based selection criteria for selecting the type and amount of surface modifiers used to obtain sub-micron size stable suspensions.

Selon cette invention, on prépare des particules stables microniques et sub-microniques de médicaments ou d'autres produits d'utilité industrielle, qui sont insolubles ou faiblement solubles dans l'eau et suspendus dans un milieu liquide comprenant au moins un modificateur de surface, en sélectionnant le ou les modificateur(s) de surface de manière à ce que le rapport hydrophile-lipophile (HLB) de la composition, qui est défini comme formule (I) doit être compris entre 4 et 9. Ce procédé permet d'obtenir un critère de sélection fiable sur la base du HLB, qui permet de sélectionner le type et la quantité des modificateurs de surface utilisés pour obtenir des suspensions stables de taille sub-micronique.
