Optimize the release kinetics of your drug delivery system with our poly (D,L-lactic acid)(PLA) and/or poly (D,L-lactic-co-glycolic acid) (PLGA) biodegradable polymers. Our wide portfolio of top-quality biodegradable polymers has an excellent track record of customer and FDA audits, manufactured in Europe to robust QC specifications that were developed with the end dosage form in mind.
Our SAFC® portfolio of high-quality products for biopharmaceutical and pharmaceutical formulation and production withstands strict quality control procedures and is produced according to applicable cGMP guidelines.
Poly(lactide-co-glycolide)s (PLGAs) are copolymers consisting of lactic and glycolic acid. Due to their inherent ester bonds PLGAs are degraded upon exposure to physiological conditions into biocompatible degradation products. These characteristics make PLGAs the most successful polymeric biomaterials for use in sustained release drug formulations. In these formulations the API is embedded into a biodegradable polymer matrix which releases the API at a constant rate over a defined period of time while being degraded.
