摘要：PURPOSE: A porous microsphere for pulmonary administration and a method for manufacturing the same are provided to enable controlled release of physiologically active agent. CONSTITUTION: A porous microsphere for pulmonary administration contains micropores on the surface and inside of microsphere body of biodegradable polymer. The coefficient of variation of the microsphere and micropore is under 0.2. The diameter of the microsphere body and micropore is 1-300 um and 80 nm-1.5 um, respectively. The physiologically active agent is drug, gene, vaccine, peptide or mixture thereof.
