A study of drug release from homogeneous PLGA microstructures.

The hydrogel template method was used to fabricate homogeneous drug-PLGA microparticles. Four drugs (felodipine, risperidone, progesterone, and paclitaxel) were loaded into the PLGA particles with the homogeneous size of 10microm, 20microm, and 50microm. The drug loading into the PLGA microparticles was 50% and higher.
