Serum aminotransferase levels are frequently elevated in patients with visceral leishmaniasis and miltefosine therapy regularly results in a decline in mean values into the normal range. In prospective studies of miltefosine therapy, however, as many as half of patients had mild-to-moderate ALT elevations during therapy, although values above 5 times ULN were rare (

Miltefosine has demonstrated activity against Leishmania parasites and neoplastic cells primarily due to its effects on apoptosis and disturbance of lipid-dependent cell signalling pathways. Several potential antileishmanial mechanisms of action have been proposed, however no mechanism has been identified definitely. Within the mitochondria, miltefosine inhibits cytochrome-c oxidase leading to mitochondrial dysfunction and apoptosis-like cell death. Antineoplastic mechanisms of action are related to antileishmanial targets and include inhibition of phosphatidylcholine biosynthesis and inhibition of Akt (also known as protein kinase B), which is a crucial protein within the PI3K/Akt/mTOR intracellular signalling pathway involved in regulating the cell cycle. Animal studies also suggest it may be effective against Trypanosome cruzi (the organism responsible for Chagas' disease), metronidazole-resistant strains of Trichonomas vaginalis, and it may have broad-spectrum anti-fungal activity.

Miltefosine is metabolized mainly by phospholipase D, releasing choline, choline-containing metabolites, and hexadecanol, which are likely to enter the intermediary metabolism. The metabolites produced by this reaction are all endogenous and are likely used for bio-synthesis of acetylcholine, cell membranes, and long-chain fatty acids.
