The compositions consist of a) a phospholipid of the formula <IMAGE> in which m is two or three, R1 and R2 are, independently of one another, alkyl, alkenyl or acyl each with 10 to 20 C atoms, and X is a direct bond, C1-C4-alkylene, C2-C4-alkenylene or C1-C4-alkylene or C2-C4-alkenylene substituted by hydroxyl, or a pharmaceutically acceptable salt thereof, b) a phospholipid of the formula <IMAGE> in which R3 and R4 are the acyl group of a saturated or unsaturated carboxylic acid with 10 to 20 C atoms and 1 to 2 double bonds, c) a compound or a mixture of compounds with pharmacological properties and, where appropriate, d) a lipid from the group comprising phosphatidylcholines, phosphatidylserine, phosphatidylinositol, phosphatidylglycerol, cardiolipin and cholesterol and, where appropriate, a pharmaceutically acceptable carrier solution which is buffered to pH 7.0 to 7.8 and, where appropriate, pharmaceutically acceptable auxiliaries. The compositions can be used in the form of liposomes as administration systems, for example for cancer chemotherapy. |
