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.

Packaging

1, 5 g in glass bottle

The world of commercial biomaterials has stagnated over the past 30 years as few materials have successfully transitioned from the bench to clinical use. Synthetic aliphatic polyesters have continued to dominate the field of resorbable biomaterials due to their long history and track record of approval with the U.S. Food and Drug Administration (FDA).
