Abstract

PLGA is a combination polymer of PLA and PGA which has adapted a good market value in several years due to its unique properties of remaining stable in an amorphous and semi-crystalline form. As it is biodegradable polymer [1, 2]. Its property of controlled degradation is very useful for release of drug in a controlled manner hence its use increasing very rapidly in various formulations. Present review deals with its structure, properties, degradation pattern, USFDA IIG level to be used in various formulations and available marketed formulations containing PLGA hence it effectively used in various formulations including subcutaneous implantable delivery of drugs for its sustained effects[3].
