New guidelines will help detect and study counterfeit medicines

A significant proportion of drugs consumed in the developing world are of poor quality, many of which are counterfeit, say the authors, all experts on drug quality working in Kenya, Laos, Thailand, the UK, and the US. This begs the question—how can we translate evidence on best drug treatment outcomes into treatment policy if the medicines actually used have substantially inferior effectiveness compared with the medicines originally evaluated? There are no existing guidelines about the most appropriate sampling and reporting strategies for medicine quality surveys.

Paul Newton and colleagues reviewed previous work on the quality of medicines and discuss the advantages and disadvantages of different study methods, including how to sample medicines for testing. They also reviewed how medicine quality studies have been reported and suggest a checklist of items to be addressed in future studies

The authors invite comment on their guideline proposals, saying that "The objective of the consensus guidelines presented here is to guide surveys of medicine quality and how they are reported, and to provide a template for further development."
