The main therapeutic method currently used for the treatment of vitiligo vulgaris is either photochemotherapy or corticosteroids. But both of the procedures however require lengthy treatment to obtain a satisfactory result.

To determine the increased efficacy of the combination therapy of photochemotherapy with corticosteroid and chlorpromazine compared with the usual monotherapy.

The combination therapy was done in 29 cases and the results were compared with the results of either monotherapy appearing in the literatures.

f the 29 patients, 14(48.3%) patients achieved 100% repigmentation, 7(24.1%) patients 75~50%, 5(17.2%) patients 25~50%, and 3(10.4%) patients less than 25%. For the cured patients, 190.3 days and 32.7 times of photochemotherapy were used.

The combination therapy is more effective, and the duration of treatment can be greatly reduced compared with either monotherapy.
