More than a third of malaria drugs examined by scientists in
Southeast Asia were fake, and a similar proportion analysed in Africa
were below standard, doctors warned last week.
“These findings are a wake-up call demanding a series of interventions to better define and eliminate both criminal production and poor manufacturing of antimalarial drugs,” Joel Breman of the Fogarty International Center at the US National Institutes of Health (NIH) said on May 22.
Trawling through surveys and published literature, the researchers found that in seven Southeast Asian countries, 36 percent of 1437 samples from five categories of drugs were counterfeit.
Additionally, 30pc of the samples failed a test of their pharmaceutical ingredients.
In 21 sub-Saharan countries, 20pc of more than 2500 samples tested in six drug classes turned out to be falsified, and 35pc were below pharmaceutical norms.
Sub-standard medications are a major problem in the fight against malaria, a disease which killed 655,000 people in 2010, according to the UN’s World Health Organisation (WHO).
Many of the drugs that are being faked or poorly manufactured are artemisin derivatives, the study said.
This is especially worrying as artemisinins are the frontline treatment for malaria, replacing drugs to which the malaria parasite has become resistant.
The study says there are many causes for the problem, ranging from widespread self-prescription of drugs to shoddy controls to monitor drug quality and prosecute counterfeiters.
“Poor-quality antimalarial drugs are very likely to jeopardise the unprecedented progress and investments in control and elimination of malaria made in the past decade,” said Mr Breman.
Last month, studies published in The Lancet and Science journals reported that artemisin-resistant malaria, which was first spotted in Cambodia in 2006, has since been detected 800 kilometres (500 miles) westward on the Thailand-Myanmar border.
