Abstract

To avoid the gastro intestinal side effects of the drug on chronic oral administration, to provide faster action, transdermal formulation of Aceclofenac entrapped in transfersomes was formulated and evaluated. The aim of the present study involves formulation and evaluation of transfersomes of Aceclofenac by thin film hydration technique to improve the solubility and permeability of the drug. Transferomes were prepared using phosphatidylcholine and three different surfactants (Span 20, Span 60 and Span 80) as bilayer forming components. Formulations were evaluated for different parameters like; physicochemical properties (optical microscopy, particle size distribution, zeta potential measurement, SEM), % entrapment efficiency, in vitro release and stability studies. The % entrapment efficiency of the formulations was found to be in the range of 52.96 % to 67.25 %. in vitro release studies constant release of drug for the period of 8 hrs and maximum release of drug was shown by formulation F2 (83.6%). The optimized transferomal dispersion was incorporated into gel base using Carbopol 934P and test results obtained were acceptable and transfersomes were found to be stable in gel base.
