Artemether-lumefantrine: an option for malaria.

OBJECTIVE

To review the pharmacology, pharmacokinetics, safety, and efficacy of artemether-lumefantrine for the treatment of Plasmodium falciparum malaria.

DATA SOURCES

English-language articles indexed in PubMed (1947-November 2011) were identified, using the search terms artemether-lumefantrine, artemether-lumefantrine AND malaria, Coartem, and Coartem AND malaria.

STUDY SELECTION AND DATA EXTRACTION

Available English-language articles were reviewed. In addition, the malaria treatment regimens recommended by region as provided by the World Health Organization and the treatment guidelines from the Centers for Disease Control and Prevention were reviewed.

DATA SYNTHESIS

Artemether-lumefantrine is an artemisinin-derived combination antimalarial approved by the Food and Drug Administration in 2009 for the treatment of P. falciparum malaria. The dual mechanisms of action of artemether-lumefantrine provide rapid and sustained parasite clearance. In the reviewed studies, the polymerase chain reaction (PCR)-corrected 28-day cure rates of artemether-lumefantrine were noninferior to the most common comparators, including chloroquine, dapsone, and other artemisinin derivatives (86-100% vs 51-100%, respectively). PCR-corrected day-42 cure rates were 92-99.3% for artemether-lumefantrine versus 62-100% for the comparator groups. The major adverse effects (gastrointestinal and central nervous system) were mild to moderate in severity and did not require a change in therapy. Although adherence to artemether-lumefantrine has been described as a potential problem due to the complicated dosing schedule, studies have described clinical cure rates similar to those of other antimalarials.

CONCLUSIONS

Artemether-lumefantrine is a safe and effective treatment for children and adults with P. falciparum malaria.
