Enhancing Effect of Synthetic Borneol on Skin Permeation of Ligustrazine Hydrochloride / 中成药

ABSTRACT

Objective:To investigate the effect of synthetic borneol on penetration mechanism of ligustrazine hydrochloride. Methods: Permeation tests in vitro through rabbit skin in two compartment diffusion cells were performed to study the effect of synthetic borneol on transdermal absorption of ligustrazine hydrochloride by changing concentrations of synthetic borneol and rabbit skin condition. Results: Ligustrazine hydrochloride permeation coefficient increased linearly with incerease of concentrations of synthetic borneol, while those through strippde stratum corneum skin were not varied. Synthetic borneol enhanced the deposit functions of whole skin and stripped stratum corneum skin. Conclusions: Synthetic borneol could enhance the percutaneous absorption of ligustrazine hydrochloride, mainly through the stratum corneum, and increase the deposit function.
