Abstract:
Keloid and hypertrophic scars are difficult to manage and remain a therapeutic challenge. Verapamil has shown a great potential in the management of keloid and hypertrophic scars. Comparing with conventional corticosteroid injections, verapamil could improve the appearance of keloid and hypertrophic scars, and is associated with a lower incidence of adverse effects. Is verapamil an effective alternative modality in the prevention and treatment of keloid and hypertrophic scars? The aim of this study was to assess the effectiveness of verapamil in preventing and treating keloid and hypertrophic scars. Searches were conducted in Medline, EMbase and Cochrane databases from 1974 to January 2015. The selection of articles was limited to human subjects. Five randomised controlled trials (RCTs) or cluster-randomised trials or controlled clinical trials (CCTs) comparing the efficacy of verapamil with conventional treatments were identified. The results showed that verapamil could improve keloid and hypertrophic scars, and was not significantly different from conventional corticosteroid injections. Few adverse effects were observed. However, this result should be considered carefully, as most of the included studies have a high risk of bias because of issues with randomization, allocation concealment, blinding, incomplete outcomes and selective reporting. In conclusion, verapamil could act as an effective alternative modality in the prevention and treatment of keloid and hypertrophic scars. More high-quality, multiple-centre, large-sample (RCTs) are required to define the role of verapamil in preventing and treating keloid and hypertrophic scars.
