Tailoring of HPMC-Zein Based Film Forming Gel of 5-fluorouracil for Treat-ment of Stable Vitiligo: a Strategy Assisted by Carbon Dioxide Laser Dermabra-sion

Vtiligo, a significant dermatologic challenge affecting 0.5 to 2% of the global population. Despite various existing medical approaches, current vitiligo treatments are still far from optimal. 5FU is a well-known chemotherapeutic agent that has been used for colorectal cancer treatment. The drug prevents DNA synthesis by inhibiting the thymidylate synthetase. The hyperpigmenta-tion of the skin is the most side effect observed with 5-FU therapy which directed its use in treat-ment of vitiligo. Besides, many studies reported that 5-FU could induce regimentation in vitiligo by direct stimulation of melanocytes and increasing melanosomes numbers in the keratinocytes.
