Abstract
The invention relates to a pharmaceutical implant for controllably releasing a drug in a subject and methods for manufacturing and administering the implant. The implant is made of associated microparticles of a drug dispersed in a biodegradable polymer. The microparticles are sufficiently associated so that the implant maintains a predetermined shape but are not fused together so as to form a single monolithic structure. The drug can be controllably released in a subject by administration of the pharmaceutical implant without the need of a suspending fluid.
