Abstract:
OBJECTIVETo study the transdermal permeation and in vivo pharmacokinetics of effective constituent ferulic acid from Ligusticum chuanxiong, in order to establish the in vitro/in vivo correlation in transdermal permeation.
METHODFranz diffusion cell was adopted in the in vitro transdermal permeation, with CD-1 nude rat abdominal skin as the permeation medium. Linear probes were implanted in CD-1 nude rats. With PBS as perfusate, microdialysis was employed to study the pharmacokinetics. Ferulic acid concentrations in the receptor solution and dialysate were assessed by high performance liquid chromatography (HPLC). The study on correlation between in vitro and in vivo data was conducted by deconvolution methods.
RESULTThe transdermal permeation rate of ferulic acid from Ligusticum chuanxiong was (0.094 4 +/- 0.049 4) microg x cm2 x min, with Cmax of ferulic acid being 808.91 microg x L(-1), and Tmax being 183 min after dermal administration. The in vitro/in vivo correlation was 93.61.
CONCLUSIONFerulic acid in extracts from L. chuanxiong can quickly penetrate skins. By using the in vitro/in vivo correlation in transdermal permeation, simple in vitro transdermal permeation method can be adopted to study the changes in its pharmacokinetics.
