Abstract

On procède à la microencapsulation par séparation de phases de substances médicamenteuses hydrosolubles. Les opérations de l'étape de durcissement se déroulent à une température comprise entre env. 0 et env. 25 degrés C, le non-solvant utilisé lors de cette étape étant un hydrocarbure aliphatique fluoré ou fluorohalogéné ou un mélange de tels hydrocarbures. Le non-solvant est en outre utilisé en excès par rapport au volume de solvant et non-solvant provenant de l'étape de séparation de phases.
