Antimalarial agents are a class of drugs used to treat and prevent malaria, a life-threatening disease caused by parasites. There are several synonyms for antimalarial agents, including antimalarials, antiparasitics, antiprotozoals, and antimalarial medications. These drugs work by targeting the parasite responsible for malaria, preventing it from replicating and spreading throughout the body. Some of the most commonly used antimalarial agents include chloroquine, quinine, mefloquine, and artemisinin-based combinations. It is important to note that the effectiveness of antimalarial agents can vary depending on the type of malaria and the resistance patterns of the local parasite population. Consultation with a healthcare professional is necessary for proper diagnosis and treatment of malaria.
