'Miltefosine' (
INN, trade names 'Impavido' and 'Miltex') is an
antiprotozoal drug. Originally developed as an
antineoplastic, it is now registered and used by
Zentaris GmbH in
India,
Colombia and
Germany for the treatment of
visceral and
cutaneous leishmaniasis, and is undergoing
clinical trials for this use in several other countries, such as
Brazil[ Hospital de Doenças Tropicais testa droga contra calazar Márcia Cristina ] and
Guatemala.

Recent animal studies suggest miltefosine may also be effective against ''
Trypanosoma cruzi'', the
parasite responsible for
Chagas' disease,

pathogenic
fungi, including ''
Cryptococcus neoformans'', ''
Candida'', ''
Aspergillus'' and ''
Fusarium''.

Hexadecyltrimethylammonium bromide, a compound structurally similar to miltefosine, was recently found to exhibit potent ''
in vitro'' activity against ''
Plasmodium falciparum''.
