Abstract: The drugs available for the treatment of cutaneous leishmaniasis have unsatisfactory efficacy, frequent and serious adverse effects, and require long treatment regimens. Thus, the search for new treatment alternatives for cutaneous leishmaniasis is considered a priority by the World Health Organization. Parenteral administration of pentavalent antimonials for the treatment of all forms of leishmaniasis, including cutaneous leishmaniasis, has several limitations. The therapy is long, requires repeated doses, and adverse reactions are frequent. Topical treatment is an attractive alternative for cutaneous leishmaniasis, offering significant advantages over systemic therapy: fewer adverse effects, ease of administration, and lower costs. The present inventors aimed to provide a fixed-dose topical composition containing at least one antileishmanial compound, providing adequate absorption of the active ingredient.

Abstract: The present invention is directed to a suitable topical composition for cosmetic, pharmaceutical or dermatological use. In a particular aspect, it is a stable nanoemulsion whose particles have a narrow size distribution range. In another particular aspect, the invention is directed to an improved process for producing said composition.
