Used primarily in the treatment of leishmaniasis, a parasitic disease transmitted by sandfly bites. It acts by interfering with the energy metabolism of the parasite, effectively killing the Leishmania organisms. Administered via intravenous or intramuscular injection, it is especially utilized in regions where the disease is endemic, such as parts of South Asia, Africa, and South America. Despite its efficacy, it requires careful monitoring due to potential side effects, including cardiac and liver toxicity. It remains a key therapeutic option in resource-limited settings where alternative treatments may not be available.
