Patent

CA 2155085

A process is disclosed for processing hardly soluble active substances together with phospholipids into a homogeneous solution. The process is characterized in that a) the active substance is mixed with a phospholipid, b) and acid aqueous solution of a carbohydrate is added to the residue at an increased temperature and the mixture is stirred at an increased temperature until a homogeneous colloidal solution is obtained, and c) this solution is cooled, set at a pH value from 4 to 5 and sterilized.
