title: Artemether-lumefantrine for treating uncomplicated falciparum malaria.
abstract: BACKGROUND
  Artemether-lumefantrine is being recommended by the World Health Organization for treating uncomplicated malaria. It is expensive. We sought evidence of its superiority over existing treatment regimens.
  
  
  OBJECTIVE
  To compare artemether-lumefantrine with other antimalarial drugs for treating uncomplicated falciparum malaria.
  
  
  METHODS
  We searched the Cochrane Infectious Diseases Group specialized trials register (February 2003), the Cochrane Controlled Trials Register (Issue 1, 2003), MEDLINE (1966 to February 2003), EMBASE (1988 to February 2003), conference proceedings, and reference lists of articles. We contacted experts in malaria research and the pharmaceutical company that manufactures artemether-lumefantrine.
  
  
  METHODS
  Randomized and quasi-randomized trials comparing artemether-lumefantrine administered orally with standard treatment regimens (single drug or combination).
  
  
  METHODS
  Two reviewers independently applied inclusion criteria to potentially relevant trials, assessed trial quality, and extracted data. Parasitaemia on day 28 (day 42 for sulfadoxine-pyrimethamine and day 63 for mefloquine) was the primary outcome. Adverse event information was collected from the studies.
  
  
  RESULTS
  Six trials (1698 participants) tested a four dose regimen. Failure rates for artemether-lumefantrine tended to be higher (comparisons included sulfadoxine-pyrimethamine, halofantrine, and mefloquine; difference statistically significant for mefloquine). When compared with chloroquine, artemether-lumefantrine was better in two studies, but the failure rate for chloroquine at these sites was over 50%. Two trials (419 participants) tested a six dose regimen against mefloquine plus artesunate. Artemether-lumefantrine was associated with higher failure rates but the studies were small.
  
  
  CONCLUSIONS
  The four dose regimen of artemether-lumefantrine seems to be less effective than most other current antimalarial regimens. The six dose regimen is largely untested.
