However, the WHO has recommended that a single dose of primaquine (0.25 mg/kg) is safe to give even in individuals with G6PD deficiency, for the purpose of preventing transmission of P. Primaquine overdose can cause a dangerous reduction in various blood cell counts, and therefore should be avoided in people at risk for agranulocytosis, which include people with conditions such as rheumatoid arthritis and lupus erythematosus, and those taking concurrent medications that also decrease blood cell counts.

Antimalarial Drugs Quinine, Chloroquine & Mefloquine.. Mefloquine Dosage Guide with Precautions -. Quinine remains an important and effective treatment for malaria today, despite sporadic observations of quinine resistance. 1 Chloroquine. Research by German scientists to discover a substitute for quinine led to the synthesis in 1934 of Resochin chloroquine and Sontochin 3-methyl-chloroquine. New antimalarial drugs called chloroquine and primaquine were developed during the World War II research program and given to U. S. troops in Korea and Vietnam. “But they had a lot of the same problems as atabrine,” Nevin says. “Everything we’re seeing with mefloquine we were seeing in World War II, Korea and Vietnam.” Mefloquine is a medicine used to treat malaria, a disease caused by parasites. This medicine works by interfering with the growth of parasites in the red blood cells of the human body.
