The release rate of maraviroc from electrospun fibers in vitro was dependent upon the drug loading, the inclusion of Tween 20, the pH of the release medium, and the polymer. (A) Release from PVP fibers with 28 wt% maraviroc (□) into pH 4.0 citrate buffer (solid line) or pH 7.0 PBS (dashed line) and 9 wt% maraviroc (□ with dot) into pH 4.0 citrate buffer (solid line) or pH 7.0 PBS (dashed line); (B) release from PVP fibers with Tween 20 with 28 wt% maraviroc (◼) and 9 wt% maraviroc (⊠); (C) release from PEO fibers with 28 wt% maraviroc (○) and 9 wt% maraviroc (⊙); (D) release from PEO fibers with Tween 20 with 28 wt% maraviroc (filled ○) and 9 wt% maraviroc (○ with x). Data are shown as the means from n = 3 independent experiments. Error bars represent SD.
