Efficacy and Safety of Calcipotriol Plus Betamethasone Dipropionate Ointment in Patients With Psoriasis Vulgaris

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the efficacy and safety of calcipotriol plus betamethasone dipropionate ointment compared with calcipotriol ointment in the treatment of patients with psoriasis vulgaris for a duration of 4 weeks. The study will focus on the percentage change of the psoriasis area and severity index (PASI) from baseline to the end of week 4.
