What is Chloroquine primarily used to treat?

Chloroquine is primarily used to treat malaria, a parasitic infection caused by Plasmodium species, which is transmitted through the bite of infected mosquitoes. The drug works by inhibiting the growth of the malaria parasite within red blood cells and is particularly effective against the blood stages of the parasite, making it a crucial treatment option in regions where malaria is endemic.

While chloroquine has historical use in the treatment of certain autoimmune conditions like rheumatoid arthritis and lupus, its primary indication remains malaria. It is important to understand that the utilization of drugs can evolve, and chloroquine has been relatively supplanted by other medications for some of these conditions due to the development of more effective treatments with fewer side effects. However, its most recognized and principal role is definitely in the management of malaria.
