Used primarily in the treatment of severe malaria, especially caused by Plasmodium falciparum. It acts rapidly to reduce parasite load and is preferred in emergency settings due to its quick onset of action. Administered via intravenous or intramuscular routes in severe cases, it significantly lowers mortality compared to other antimalarials. Also investigated for potential antiviral and anticancer properties, particularly in combination therapies. Its ability to generate free radicals makes it a candidate for targeting rapidly dividing cells, such as in certain tumors. Widely used in resource-limited regions due to stability and effectiveness.
