## Abstract The maximum steady state flux, diffusion coefficients, and solubilities of five contraceptive steroids in homopolymers and copolymers of Ο΅βcaprolactone and DLβlactic acid were determined. The permeabilities of polymers of Ο΅βcaprolactone were comparable to silicone rubber and, by inferen

## Abstract DLβpoly(lactic acid) of molecular weight about 2500 was prepared by polycondensation of lactic acid and characterized by viscosimetry, infrared spectroscopy, light scattering, GPC, and NMR. Tablets made of the above polymer were immersed in buffer solutions at 37Β°C, and their swelling b
Prolonged analgesia may be achieved using a single injection of slow-release local anesthetic formulation. The study objective was to improve the efficacy of a previously reported formulation comprising 10% bupivacaine in poly(DL:lactic acid co castor oil) 3:7. The polymer was loaded with 15% bupiva
This study was designed to investigate the in vitro degradation of thin poly(DL-lactic-co-glycolic acid) (PLGA) films for applications in retinal pigment epithelium transplantation and guided tissue regeneration. PLGA films of copolymer ratios of 75:25 and 50:50 were manufactured with thickness leve
