Melarsoprol

Melarsoprol is a medication used to treat advanced-stage sleeping sickness (trypanosomiasis), a disease caused by parasites transmitted by tsetse flies. It contains a compound called arsenic, which helps eliminate the parasites from the body's nervous system. While effective, melarsoprol can have serious side effects, including allergic reactions and neurological problems, so it is typically reserved for severe cases when other treatments are ineffective. Its use requires careful monitoring by healthcare professionals to balance benefits and risks.
