Bad malaria pills in Africa raise resistance fears

Between 16 per cent and 40 per cent of artemisinin-based drugs sold in Senegal, Madagascar and Uganda failed quality testing, for reasons including impurities or not containing enough active ingredient, the survey found.

Artemisinin-based drugs are the only affordable treatment for malaria left in the global medicine cabinet. Other drugs have already lost effectiveness due to resistance, which builds when not enough medicine is taken to kill all of the mosquito-transmitted parasites.

If artemisinin-based drugs stop working, there is no good replacement and experts worry many people could die.

"It is worrisome that almost all of the poor-quality data that was obtained was a result of inadequate amounts of active [ingredients] or the presence of impurities in the product," said Patrick Lukulay, director of a nongovernmental U.S. Pharmacopeia program funded by the U.S. government, which conducted the survey. "This is a disturbing trend that came to light."

The study is the first part of a 10-country examination of antimalarials in Africa by the U.S. and the World Health Organization. It follows evidence from the Thai-Cambodian border that artemisinin-based drugs there are taking longer to cure malaria patients, the first sign of drug resistance.
