Benefits
- Combination therapy for rapid and complete elimination of malaria parasites

How It Works
Coartem 80/480mg works through a dual mechanism of action. Artemether, a derivative of artemisinin, rapidly reduces the malaria parasite load through potent antimalarial activity. Lumefantrine, a long-acting antimalarial agent, eliminates any remaining parasites in the body, preventing recurrence of infection.
Duration of Action
Artemether begins working within hours of administration, with a short half-life of 2-3 hours. Lumefantrine provides extended antimalarial action with a half-life of 3-6 days, ensuring complete parasite elimination.
