PLGA: A Cornerstone Biopolymer in Modern Biomedical Science
Introduction to PLGA
Polylactic-co-glycolic acid (PLGA) is a biodegradable copolymer composed of lactic acid and glycolic acid. Due to its excellent biocompatibility and tunable degradation rates, PLGA has become a cornerstone material in the development of medical devices, drug delivery systems, and tissue engineering scaffolds.
Its approval by global regulatory bodies such as the U.S. Food and Drug Administration (FDA) further underscores its safety and reliability for clinical use.
Key Properties of PLGA
PLGA’s versatility stems from its ability to degrade safely within the human body, producing naturally occurring byproducts. Its performance can be customized by adjusting the ratio of lactic to glycolic acid.
Notable Features:
Biodegradable and biocompatible
Controlled degradation profile
Excellent mechanical strength
Safe metabolic byproducts (lactic acid and glycolic acid)
FDA and EMA approved for various medical applications
Applications of PLGA in Medicine
1. Drug Delivery Systems
PLGA is widely used to develop sustained and controlled drug release systems. It helps improve patient compliance by reducing dosing frequency and ensuring a steady release of therapeutic agents over time.
2. Tissue Engineering
As a scaffold material, PLGA supports cell adhesion, proliferation, and differentiation, making it ideal for regenerating bone, cartilage, skin, and nerve tissues.
3. Surgical Devices
PLGA is employed in absorbable sutures, pins, screws, and implants that gradually dissolve in the body, eliminating the need for secondary surgeries.
4. Vaccine Delivery
Microparticles made from PLGA can encapsulate antigens, acting as vaccine carriers that ensure prolonged immune system stimulation.
