Background
Annually, millions of people suffer from skin scars’ psychological and physical disadvantages. Pathologic scars prevention is challenging and requires developing feasible and effective therapeutic strategies. Regarding promising results of losartan (an angiotensin 1 receptor inhibitor) on skin scar in preclinical studies, we aimed to assess the losartan ointment’s impact on surgical scars in a clinical setting.
Material and Method
Twenty-four patients with surgical wounds were enrolled from Razi hospital’s plastic and reconstructive surgery department. The patients were trained to apply ointments 14–18 days post-surgery on the determined scar side, twice a day for 6 months. Two dermatologists independently evaluated scar formation at 3 and 6-month follow-ups using the Vancouver Scar Scale (VSS) score.
Result
Twenty-four female patients with cosmetic surgeries were included. The mean VSS score of losartan-treated sides was 7.1 ± 2.06 (at month 3) and 5.21 ± 1.71 (at month 6) that significantly were different from placebo-treated sides (9.77 ± 1.55 and 8.31 ± 1.88 at 3 and 6 months, respectively) (P value < 0.001 and < 0.001, respectively, for months 3 and 6). The subset analysis demonstrated a significant improvement in height (P value < 0.001 at 3 and 6 months), pliability (P value < 0.001 at 3 and 6 months), and vascularity (P value < 0.001 at 3 and 6 months) subsets at losartan compared to placebo-treated side. Losartan ointment was well tolerated with no complication.
Conclusion
Losartan ointment successfully improved scar formation in mammoplasty and abdominoplasty patients. The losartan preventive effect should be confirmed in future large-scale studies with long-term follow-ups.
