5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Antimalarials

Agents used in the treatment of malaria. They are usually classified on the basis of their action against plasmodia at different stages in their life cycle in the human. (From AMA, Drug Evaluations Annual, 1992, p1585) (See all compounds classified as Antimalarials.)
