Meglumine antimoniate is a medication primarily used to treat leishmaniasis, a disease caused by parasites transmitted through the bites of infected sandflies. It contains antimony, which helps to kill the parasites and reduce symptoms associated with the infection. This drug is typically administered through injection and is effective against various forms of leishmaniasis, including cutaneous leishmaniasis and visceral leishmaniasis. While it is generally well-tolerated, some patients may experience side effects such as pain at the injection site or gastrointestinal issues.
