Summary for Patent: 10,195,138

Title:	Methods for the preparation of injectable depot compositions
Abstract:	Injectable depot compositions, comprising a biocompatible polymer which is a polymer or copolymer based on lactic acid and/or lactic acid plus glycolic acid having a monomer ratio of lactic to glycolic acid in the range from 48:52 to 100:0, a water-miscible solvent having a dipole moment of about 3.7-4.5 D and a dielectric constant of between 30 and 50, and a drug, were found suitable for forming in-situ biodegradable implants which can evoke therapeutic drug plasma levels from the first day and for at least 14 days.
