Microparticles consisting of (a) a matrix with a mixture of (a1) at least one hydrophobic, biologically degradable polymer and (a2) optionally at least one water-soluble polymer, (b) a pharmaceutical active ingredient distributed in the matrix, and (c) in addition at least one water-insoluble, surface-active substance from the group of lecithins and phospholipids, distributed in the matrix, and a three-phase emulsion process for their preparation.
