Presenter Dr. Tanmay Mehta MD, DNB, PGDCTM In Plasmodium falciparum quinine has been found to inhibit nucleic acid synthesis, protein synthesis, and glycolysis; it also binds with hemazoin in parasitized erythrocytes. Quinine is effective as a malarial suppressant and in control of overt clinical attacks. Its primary action is schizontocidal. Chloroquine. For treatment and chemoprophylaxis since the 1940s,drug resistance. Oral use ; Antimalarial Action ; Highly effective blood schizonticide.
