Abstract
Simple mixing/blending of a special class of drug-depot forming tri-block copolymers polymers, with the opportunity to cost-effectively tailor drug delivery performances of such biodegradable, injectable depots in a clinical and an industrial setting. How to visualize these depots for various imaging related purposes is described. A composition comprising (a) an active ingredient, preferably a pharmaceutically active ingredient (b) a solvent and (c) a mixture of at least two types of tri-block copolymers of formula (1)B-A-B  (1)wherein B stands for a hydrophobic block and wherein A stands for a hydrophilic block, wherein the mixture is prepared by mixing at least two types of tri-block copolymers having a degree of modification of 100% and wherein the at least two types of B-A-B types of tri-block copolymers differ only on the type of end-group or wherein the mixture is prepared by mixing at least two types of tri-block copolymers, wherein one of the at least two tri-block copolymers has a degree of modification of 100% and one of the at least two tri-block copolymers has a degree of modification of 0% and wherein the at least two types of B-A-B types of tri-block copolymers differ only on the degree of modification of the end-groups.
