Therapeutic Class

Antimalarial drugs

Dosage Form, Composition & NAFDAC Registration Number (NRN)

Suspension (NRN: 04-3266): Each 5 mL of suspension contains: Artemether 15 mg.

Pack size: 100 mL (in a bottle with measuring cap which is calibrated in divisions of 5 mL).


Artemether and its derivatives act essentially as blood schizonticides. The presence of the endoperoxide bridge appears to be essential for

antimalarial activity, generation of singlet oxygen and formation of free radicals. Inhibition of protein synthesis as the basic mechanism of action

is suggested in studies which showed morphological changes in ribosomes as well as in the endoplasmic reticulum.


Oral Artemether is rapidly absorbed reaching Cmax within 2-3 hours. It is metabolized in the liver to the demethylated derivatives dihydroartemisinin.

The elimination is rapid, with a T½ of 4 hours. Dihydroartemisinin has T½ of more than 10 hours.


For the treatment of malaria caused by all types of Plasmodium including multiple drug resistant strains; for the treatment of severe P. falciparum malaria.
