A process for producing active ingredient-containing aqueous liposome suspensions

Described is a process for the preparation of aqueous liposome suspensions containing active substances, the suspensions being prepared from a solution of a liposome-forming substance, or mixture of such substances, in a lower alcohol with a maximum of three carbon atoms and an aqueous phase, the active ingredients being dissolved or suspended in the lipid solution and/or the aqueous phase. The process is characterized in that the aqueous phase is incorporated, by mixing, in the alcoholic solution and the lower alcohol removed by vacuum distillation and, if necessary, the liposome suspension freeze-dried.
