Development of Transdermal Patch Loaded with Pitavastatin and Ezetimibe

The present worked aimed at preparing transdermal patches of a combination of Pitavastatin and Ezetimibe to enhance the systemic absorption of both these drugs. Pitavastatin and Ezetimibe transdermal patches formulated with PEG-400 as plasticizer and polymers HPMC and ethyl cellulose by solvent evaporation method are quite stable. The weight variation of the patches was found to be between 1.032±0.092 gm to 0.917±0.085 gm. Thickness of the patches ranged from 0.27±0.04 mm to 0.18±0.05 mm and folding endurance was found between 137±49.10 to 510.25±49.10. The results reflect the ability of patches to withstand rupture satisfactorily. The drug in transdermal patches formulated ranged between 97.15 ± 3.36 to 88.64 ± 3.01% and 98.16 ± 6.95 to 82.49 ± 7.81% for Ezetimibe and Pitavastatin respectively. The low coefficient variation value indicates the uniformity of drug content in all formulations. The combination of HPMC and ethyl cellulose had enhanced diffusion rate.
