Comparing intralesional triamcinolone and verapamil-triamcinolone injections in keloids: A single-blinded randomised clinical trial.

Abstract

In this clinical trial, we investigated the efficacy of two treatment methods for keloids resulting from surgical incisions: intralesional triamcinolone injections alone versus in combination with verapamil. Patients were divided into two groups: one received triamcinolone alone (Group T) and the other received a triamcinolone-verapamil blend (Group VT). Regular treatments were conducted until the keloids were nearly flat or for a maximum of eight sessions. Both groups showed significant improvements, but Group VT saw quicker resolution of skin redness and needed fewer sessions. Though the Vancouver Scar Scale (VSS) scores were generally similar across both groups, Group VT exhibited greater improvements, leading to lower final scores. The VT group also attained normal scar flexibility faster than the T group. These findings suggest that the combination of verapamil and triamcinolone provides a more effective treatment for keloids, thereby highlighting the potential of verapamil in scar reduction.
