What this trial studies

This clinical trial aims to assess the toxicity and efficacy of topical minoxidil in patients with acne vulgaris. Participants aged 20 to 50 with mild to moderate acne will undergo baseline blood and urine tests, and their acne lesions will be monitored over a 14-day period. The primary objective is to evaluate the safety of minoxidil, while secondary objectives include measuring the response rate and time to resolution of acne lesions. Daily photographic documentation will be used to track treatment efficacy.

Why it matters

Potential benefit: If successful, this treatment could provide a new topical option for patients suffering from acne vulgaris.

How similar studies have gone: While topical minoxidil is primarily known for hair loss treatment, its application in acne vulgaris is novel and has not been extensively tested in prior studies.
