ABSTRACT
Keloid and hypertrophic scars are two types of fibrosis caused by extracellular matrix overexpression, and angiotensin II via AT1 receptor is known to play a key role in stimulation of fibrosis. A pilot placebo controlled single blind study was carried out on patients with hypertrophic scars and keloids. A total of 37 adult volunteers were randomly assigned into losartan 5% or placebo treatment groups. The treatment was performed twice a day for three months and a 6-month follow-up. The treatment was evaluated using Vancouver scar scale method. Totally, 30 participants were analyzed (Losartan ointment n = 20; placebo ointment n = 10; seven placebo volunteers left the study because they thought the treatment was not effective for them). In the losartan group, VSS scores dropped significantly (p < 0.01) both in keloid and hypertrophic scar patients. Vascularity and pliability were significantly reduced by losartan treatment (p < 0.05). It can be concluded that losartan potassium ointment (5%) can alleviate the keloid and hypertrophic scar.
