| Abstract: | The objective of the present study is to formulate and characterize propranolol hydrochloride (PPL?·?HCl) gel, and to evaluate the efficacy of this formulation in transdermal treatment for superficial infantile hemangioma (IH). The transdermal PPL?·?HCl gel was prepared by a direct swelling method, which chose hydroxypropyl methylcellulose (HPMC) as the matrix and used terpenes plus alcohols as permeation enhancer. Permeation studies of PPL?·?HCl were carried out with modified Franz diffusion cells through piglet skin. Our results pointed to that among all studied permeation enhancers, farnesol plus isopropanol was the most effective combination (Q24, 6027.4?±?563.1?μg/cm2, ER, 6.8), which was significantly higher than that of control gel (p?
