| ABSTRACT Treatment of cutaneous leishmaniasis (CL) is difficult due to the scarce number of drugs able to eliminate completely the intracellular form of the parasite. In the present study, the aim was to evaluate: i) phytochemical properties of extracts from Libidibia ferrea; ii) antileishmanial activity of extracts from L. ferrea against promastigotes and amastigotes of Leishmania (Leishmania) amazonensis and Leishmania (Viannia) guyanensis; iii) the effects of topical treatment using hydrogel containing active extract of L. ferrea on golden hamsters infected with L. (L.) amazonensis. Extracts from leaves, branches and fruits of L. ferrea were obtained with hexane and methanol and were tested by in vitro assays in promastigotes and murine macrophages J774... |

| ABSTRACT Current treatment of cutaneous leishmaniasis (CL) relies mainly on pentavalent antimonials salts and second-line drugs include pentamidine and amphotericin B, but these therapies have side effects and require parenteral administration. The aim of this work was to evaluate the topical formulations containing pentamidine isethionate (PI) in the experimental treatment of cutaneous leishmaniasis (CL). Golden hamsters (Mesocricetus auratus) were infected in the nose with Leishmania (Leishmania) amazonensis. Six treatment groups received different topical treatments of anhydrous or hydrating emulsions, for a maximum of 10 days, with an application of 50 mg day-1. After treatment tissue samples of lesions were evaluated by histology, transmission... |
