The objective of the present work was to compare the efficacy of two formulations (microemulsion [ME] and nanoemulsion [NE]) with marketed product on skin cancer cell lines.

METHODS
For this purpose, we studied two parameters, that is, drug release both in ex vivo conditions and cytotoxicity profile. For ex vivo skin permeability studies skin of male Sprague Dawley rats, goats, and human cadaver was selected. For in vitro cytotoxicity study, SK-MEL-5 melanoma cell lines were used. % cell death was concentration dependent.

RESULTS
The highest concentration (96 ?M) maximum cell death was found. The nanoemusion had highest inhibitory effect in any concentration than control or ME. Similar results were obtained for permeation study. NE had better permeation property than other.

CONCLUSION
Based on the permeation results, we found that highest amount of 5-fluorouracil collected in the viable part of the human cadaver and goat skin model from NE as compared to other preparations. Finally, it can be concluded that NE of the model drug had better properties in cytotoxicity and skin permeation than marketed topical product.
