WHO recommends the use of chemotherapy as the main control measure for all the types of the disease. Antimonials are the first drug of choice, but they can be replaced by amphotericin B, mitelfosine, paromomycin and pentamidine isethionate, or combinations.

Thus, the purpose of this review is to present the therapeutic arsenal available in the market and that has been investigated for this application.
