Cutaneous leishmaniasis (CL) is a major world health problem, which is increasing in incidence. Pentavalent antimonials have been considered as standard treatment for leishmaniasis. Many studies are performed to find an effective and safe treatment for patients with CL. The aim of this study was to compare the effect of oral cimetidine and low-dose systemic meglumine antimoniate (MA) with standard dose of systemic MA in the treatment of CL. This study was, to our knowledge, the first to show the effect of combination therapy oral cimetidine and MA in the treatment of CL all over the world. In this randomized double-blind placebo-controlled clinical trial, 120 patients with suspected CL were referred to the Aleppo University Hospital Clinic; 90 of these patients with the clinical and parasitological diagnosis of CL were recruited and were randomly divided into three treatment groups of 30 subjects each. Group A was treated with MA 60 mg/kg/d IM and oral placebo. Groups B and C received MA 30 mg/kg/d IM and oral cimetidine 1200 mg/d, MA 30 mg/kg/d IM and oral placebo, respectively. The duration of treatment was three weeks for all groups. The effectiveness of the treatment was classified in three levels as complete response, partial response, and no response. Data were analyzed by SPSS 19 using KI square, Mann-Whitney, Kaplan-Mayer, and ANOVA tests. At the end of the study (12 weeks), the rate of complete response was 91.11% in the first group, and 84.66% and 78.33% in groups B and C, respectively (P < 0.05). The highest response rate was for the group treated with a standard dose of systemic MA and placebo. Our results showed that although oral cimetidine and low-dose systemic MA had less efficacy in comparison to a standard dose of systemic MA in the treatment of CL, it still can be considered as a replacement therapy in high-risk patients (such as patients with heart, kidney, and/or liver disease) under close supervision of physicians.
