BACKGROUND/OBJECTIVES: Palmoplantar psoriasis is a localised variant of psoriasis. Topical therapy is the preferred treatment modality, but in severe and recalcitrant cases, systemic drugs like methotrexate are prescribed, with potential for significant adverse effects. Iontophoresis is gaining popularity in enhancing the transdermal delivery of drugs in ionic state. This study was undertaken to evaluate and compare the efficacy of topical methotrexate by iontophoresis technique with clobetasol propionate 0.05% ointment in the treatment of palmar psoriasis.
METHODS: This was a prospective randomised controlled study conducted on patients with palmar psoriasis. Group 1 patients (n = 31) were treated with once weekly iontophoretic delivery of methotrexate over 6 sittings, and group 2 patients (n = 31) were treated with clobetasol propionate 0.05% ointment, twice daily for 6 weeks. Severity of palmar psoriasis was assessed by modified Palmoplantar Pustular Psoriasis Area and Severity Index (m-PPPASI), and treatment was considered as satisfactory when there was >50% improvement.
RESULTS: Sixty two patients were recruited, of which 50 completed the study. Eight out of 25 (32%) patients in group 1 and 12 out of 25 (48%) patients in group 2 showed satisfactory improvement at the end of 6 weeks. However, this difference was statistically not significant (P = 0.25). Burn injury was noted in 12 (48%) group 1 patients with no adverse effects in group 2.
CONCLUSION: Iontophoretic delivery of methotrexate is a promising therapeutic modality, the efficacy of which is comparable to that of clobetasol propionate ointment in the treatment of palmar psoriasis.
