5. Safety information of Artemether

Poison by intramuscular route. Experimental reproductive effects. When heated to decomposition it emits acrid smoke and irritating fumes.

6. Uses of Artemether

Artemether is an antimalarial used for the treatment of multi-drug resistant strains of falciparum malaria. Arteether is the derivative of artemisinin, it is a strong schizonticide and can take rapid control of symptoms by killing plasmodium, it is much more effective than artemisinin and used for the curative treatment of all kinds of malaria, especially for the cerebal malaria , severe malaria and chloroquine-resistant malaria. It is also applied in combination with lumefantrine in clinical treatments of malaria.
