Topical Bimatoprost Solution 0.03%in Stable Vitiligo

Summary

Vitiligo is an acquired depigmentation disorder of great cosmetic importance, affecting 1-4% of the world's population. Phototherapy and topical agents such as corticosteroids, calcineurin inhibitors, and vitamin-D derivatives are basic treatment modalities have been used in vitiligo but there is still no effective and safe treatment for this disease. Resistance to therapy, treatment complications and recurrence after treatment are the major problems of the current treatments. There are no clinical studies of use of Bimatoprost in treatment of vitiligo, as it is supposed to cause more hyperpigmentation and hypertrichosis as compared to other topical prostaglandin analogues; hence, the investigators decided to use it in treatment of localized vitiligo.
