Brief Summary
-----------------
The purpose of the study is to determine the efficacy and safety of two different forms of a topical steroid (clobetasol propionate) in patients with plaque-type psoriasis.

Detailed Description
-----------------
This study is being conducted to obtain efficacy and tolerability data for two clobetasol propionate therapies in the treatment of plaque-type psoriasis. Subjects will be randomized to only one of the two therapies for treatment throughout the study.
