Features And Benefits
||Poly(D,L-lactide-co-glycolide)-block-poly(ethylene glycol)-block-poly(D,L-lactide-co-glycolide) based poly(ether ester urethane)
||PEG average Mn 400
average Mn 6,000-12,000
||1, 5 g in glass bottle
||The polymers are bioresorbable aliphatic polyesters comprised of a range of different ratios of lactide and glycolide monomers, PLA stereochemistries, and end-group functionalization. These biodegradeable homopolymers and copolymers of lactide and glycolide afford a variety of properties that range from very stiff, hard semi-crystalline materials with long degradation times, to softer, amorphous materials with faster degradation rates.
||This poly(ether ester urethane) based on PLGA-PEG-PLGA triblock copolymers linked with a diisocyanate is a biodegradable; resorbable gel former for use in drug delivery systems.
|Features And Benefits
||This polymer doesn't rely on temperature or pH to induce gelation and therefore form more consistent and faster-setting drug delivery depots.
Through combination of various gel formers and/or diluents; drug release profiles may be modulated to exhibit fast burst release through extended (up to 1 month) zero-order release profile.
