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.
Artemether when injected through IM route 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.
Treatment of malaria caused by all forms of Plasmodium including severe malaria caused by multiple drug resistant strains of P. falciparum.
Pregnancy, unless the doctor considers it essential as in the case of cerebral malaria.
In cerebral malaria and complicated malaria, general supporting therapy may be required.
The therapeutic dose (700 mg) has virtually no side effects. There are reports of laboratory abnormalities i.e. a decrease in reticulocyte count, an increase in transaminase and ECG changes (Sinus bradycardia). However, these are transient. At high doses, transient abdominal pain, diarrhoea and tinnitus can occur.
