Double-blind comparison of halcinonide solution and placebo control in treatment of psoriasis of the scalp.

Twenty-seven patients with psoriasis of the scalp participated in a double-blind, paired comparison study between halcinonide solution (0.1%) and placebo. The therapeutic response was excellent in sixteen patients treated with halcinonide and in one patient treated with placebo. In the comparative evaluation halcinonide was superior in twenty-two patients, the placebo was superior in four patients, and both drugs were equally effective in one patient. There were no adverse reactions due to halcinonide, but one patient experienced pruritus with the placebo solution.
