The present invention relates to an amphiphilic block copolymer of a hydrophilic block and a hydrophobic block with a terminal hydroxyl group wherein the terminal hydroxyl group of the hydrophobic bock is substituted with a tocopherol or cholesterol group. It also relates to polymeric compositions capable of forming stable micelles in an aqueous solution, comprising the amphiphilic block copolymer and a polylactic acid derivative wherein one or more ends of the polylactic acid are covalently bound to at least one carboxyl group.

Amphiphilic block copolymer and polymeric composition comprising the same for drug delivery

This invention relates to a composition and method for treating diseases and disorders of the prostate such as prostatitis, benign prostatic hypertrophy, and prostate carcinoma. The prostate is treated by intraprostatic injection of a biodegradable sustained release formulation. By injecting the treatment substance directly into the prostate, improved treatment results are obtained with a much lower treatment substance dosage. Additionally, by incorporating the treatment substance into a biodegradable sustained release formulation, the need for frequent repetition of injections is eliminated.
