Abstract

A method for manufacturing a drug-delivery composition includes providing at least one pharmaceutically active compound, a dry powder comprising at least a polymer, and an aqueous solution. The dry powder, the pharmaceutically active compound and the aqueous solution are mixed to form a paste-like or semi-solid drug-delivery composition, wherein the aqueous solution is added in an amount of less than or equal to twice the total dry mass of the dry powder.
