Starting soon · Not applicable · Has a placebo group
Conditions studied: Psoriasis
In brief
This study will evaluate whether pentoxifylline, when used as an add-on treatment to standard topical therapy, is effective and safe for adults with mild-to-moderate plaque psoriasis. Participants will be randomly assigned to receive either pentoxifylline or placebo twice daily for 12 weeks, while continuing their standard topical treatment. The study will compare improvement in psoriasis severity, itch, physician assessment, quality of life, and adverse events between the two groups. Participants will be followed for a total of 16 weeks.
