PG - 135-41 LID - S0378-5173(15)00331-2 [pii] LID - 10.1016/j.ijpharm.2015.04.023 [doi] AB - This study was to develop propranolol hydrochloride (PRO)-loaded liposomal gel as a topical drug delivery system. Scanning electron microscope (SEM) revealed that the liposomes were spherical and scattered in the surface of the gel. Pseudoplastic flows of PRO liposomal gel were showed after stored at three different temperatures. Besides, PRO liposomal gel showed non-irritating to the skin of rabbit. Skin deposition studies in vivo demonstrated that PRO liposomal gel can apparently increase drug content in skin compared with PRO gel. Histopathology examination showed that PRO liposomal gel could obviously weaken the barrier function of stratum corneum (SC) by comparison with PRO gel. What is more, the plasma pharmacokinetic showed the maximum concentration in plasma was 0.41 mug/mL and 1.17 mug/mL after topical and oral administration respectively. However, tissue distribution study showed PRO liposomal gel obviously changed drug distribution in tissues, significantly increased drug concentration in skin with about 74 folds compared with PRO gel. In conclusion, liposomes-based gel could be a promising vehicle as a transdermal delivery system of PRO. CI - Copyright (c) 2015 Elsevier B.V. All rights reserved.
