Flavonoids as adjuvant in psoralen based photochemotherapy in the management of vitiligo/leucoderma.

Vitiligo is a disorder characterized by the decrease in melanin pigment of skin. This depigmenting disorder has prevalence among worldwide, irrespective of age and sex. There is an existence of different treatment modalities for the management of vitiligo. But irrespective of treatment methods, the main drawback in the management of vitiligo is the occurrence of side effects during the implication of treatment. Among the treatment modalities, photochemotherapy seems to be the better choice of treatment for vitiligo. Photochemotherapy involves the usage of UV rays for photoactivation of the drug to cause photosensitization of skin which in turn leads to repigmentation. The main aim of the study is to develop novel combination strategy of lipid based nanoemulsion gel for the treatment of leucoderma using trimethylpsoralen and flavonoid. We assume that if this hypothesis of combination therapy proves successful it can be used as an additional novel treatment strategy in the management of vitiligo.
