Evaluation of psoralen with solar ultraviolet light (puvasol) and adjunctive topical tar therapy in psoriasis.

ABSTRACT

Fifty patients having psoriasis were studied with a view to assess the efficacy of 'puvasol' (Oral psoralen with sun-rays exposure) alone and in combination with topical tar therapy and were placed in 2 groups, each group being consisted of 25 patients. At the end of 8 weeks, out of 25 patients (Group 1) receiving 'Puvasol' in combination with topital tar therapy 15 patients (60%) showed complete clearance, marked improvement of lesions were seen in 4 cases (16%) and deterioration in one case (4%). Out of 25 patients (Group I) receiving 'Puvasol' alone 8 cases (32%) showed complete clearance of lesions and 11 patients (44%) showed marked im-provement of lesions. It is found that topical tar therapy when used as an adjunct to 'Puvasol' was more effective than 'Puvasol' alone.
