Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking double blind (subject, caregiver, investigator, outcomes assessor)
Primary purpose treatment

(Placebo Comparator)
Patients with cutaneous leishmaniasis treated with pentavalent antimony/metilglucamine 20mg/kg/day during 20 days and placebo pills three times a day during 20 days.

Primary Outcomes

Cure rate or complete cicatrization of the ulcer.
time frame: 6 months

Secondary Outcomes
