Abstract

The objective of the present study was to develop the controlled release transdermal drug delivery systems of Lovastatin using transfersomes incorporated in gels, which will control the release of drug, increasing the bioavailability of the drug and thus decreasing the dosing frequency of the drug. It was investigated by encapsulating the drug in various transfersomal formulations composed of various ratios of Soya Lecithin: Span 80 or Tween 80 or sodium deoxycholate prepared by rotary evaporation sonication method. Lipid:surfactant ratio of 90:10 is more effective when compared to other ratios. Experimental results of the present study showed that deformable lipid vesicles improve the transdermal delivery, prolong the release, and improve the site specificity of the lipophilic model drug, Lovastatin. The drug diffusion studies showed that a Transfersome vesicle follows zero order kinetics and mechanism of release follows peppas model.
