Chemical Structure of PLGA

PLGA is a linear aliphatic polyester synthesized by ring-opening polymerization of lactide and glycolide monomers. By varying the lactic acid to glycolic acid (LA:GA) ratio, the physicochemical properties such as crystallinity, hydrophilicity, and degradation rate can be precisely controlled.

Key Features

• Tunable degradation rates ranging from weeks to months through LA:GA ratio and molecular weight control
• Excellent encapsulation efficiency for peptides, proteins, small molecules, and vaccines
• Available in acid-terminated and ester-terminated grades for formulation optimization
• Well-established safety profile with extensive regulatory acceptance

Applications in Drug Delivery

PLGA is extensively used in advanced drug delivery systems such as microspheres, nanoparticles, and implants. These systems enable sustained and controlled release of active pharmaceutical ingredients, improving therapeutic efficacy while reducing dosing frequency and side effects.

Typical applications include long-acting injectable depots for peptides and hormones, vaccine delivery systems, and biodegradable implants for oncology and chronic disease management.
