Anticoagulation and Drug Release Behavior of Curcumin-Loaded PLGA Films

Abstract

Three kinds of curcumin-loaded films (3wt%, 5wt%, 8wt%) were prepared using poly(lactic acid-co-glycol acid (PLGA) as the carrier of curcumin, and studied. The result of Fourier transform infrared spectroscopy (FTIR) and X-ray electron spectroscopy (XPS) show that the curcumin is dispersed in the PLGA films. High performance liquid chromatography (HPLC) analysis suggests that the release of curcumin can last 22-43 days. A fewer number of adhered and activated platelets are observed on the curcumin-loaded PLGA films. The activated partial thromboplastin time (APTT) increases for all curcumin-loaded films.
