Opis ogólny

Poly(lactide-co-glycolide)(PLGA) is a biodegradable polymer used in the preparation of polymericmicrospheres. These polymers degrade in vivo by hydrolysis of their esterbackbone into non-toxic products, which are excreted by the kidneys oreliminated as CO2 and water through biochemical pathways. PLGAmicrospheres have been widely used to encapsulate drug molecules and have beenused as long-acting, sustained-release pharmaceutical formulations.

Zastosowanie

Poly(lactide-co-glycolide)(PLGA) can be used to fabricate sustained-release drug delivery systems, for example, it can be used to encapsulate the anti-inflammatory lipophilic drug atorvastatin.

Chronic pain after inguinal hernia repair occurs in 16% to 62% of patients. The underlying mechanism probably involves sensory nerve damage and abnormal healing that might be influenced by the materials chosen for the procedure. We hypothesize that nonabsorbable sutures
