General description

Characteristic properties of ester terminated poly(D,L-lactide-co-glycolide) (PLGA) are in vivo biodegradability, tunable drug release profile and very high encapsulation capacity.

Application

PLGA polymers find uses in the production of biodegradable medical sutures and for controlled drug release. PLGA microspheres have been reported for use in controlled release of human growth hormone. Thin membranes of blended polymers constituting of PLGA/polycaprolactone/β-tricalcium phosphate have been used in guided bone regeneration.

Features and Benefits

Controlled release of bioactive agents, sutures and bioabsorbable implantable devices.

Physical form

Biocompatible, biodegradable polymer.
