Artemether is an antimalarial drug for uncomplicated malaria caused by P. falciparum (and chloroquine-resistant P. falciparum) or chloroquine-resistant P. vivax parasites.[8] Artemether can also be used to treat severe malaria.[2]
The World Health Organization (WHO) recommends the treatment of uncomplicated P. falciparum with artemisinin-based combination therapy.[9] Given in combination with lumefantrine, it may be followed by a 14-day regimen of primaquine to prevent relapse of P. vivax or P. ovale malarial parasites and provide a complete cure.[10]
Artemether can also be used in treating and preventing trematode infections of schistosomiasis when used in combination with praziquantel.[11]
Artemether is rated category C by the FDA based on animal studies where artemisinin derivatives have shown an association with fetal loss and deformity. Some studies, however, do not show evidence of harm.[12][13]
Plasma artemether level was found to be lower when the combination product was used with lopinavir/ritonavir.[16] There is also decreased drug exposure associated with concurrent use with efavirenz or nevirapine.[17][18]
Artemether/lumefantrine should not be used with drugs that inhibit CYP3A4.[19]
Hormonal contraceptives may not be as efficacious when used with artemether/lumefantrine.[19]
