Abstract: The present invention relates to a method for the sustained release in vivo of a biologically active labile agent comprising administering to a subject in need of treatment an effective amount of a sustained release composition comprising a biocompatible polymer having the biologically active labile agent incorporated therein, and a corticosteroid wherein the labile is released for a period of at least about two weeks. It is understood that the corticosteroid is present in an amount sufficient to modify the release profile of the biologically active labile agent from the sustained release composition. Pharmaceutical compositions suitable for use in the method of the invention are also disclosed.

Abstract: Injectable compositions having improved injectability. The injectable compositions include microparticles suspended in an aqueous injection vehicle having a viscosity of at least 20 cp at 20° C. The increased viscosity of the injection vehicle that constitutes the fluid phase of the suspension significantly reduces in vivo injectability failures. The injectable compositions can be made by mixing dry microparticles with an aqueous injection vehicle to form a suspension, and then mixing the suspension with a viscosity enhancing agent to increase the viscosity of the fluid phase of the suspension to the desired level for improved injectability.
