ReviewAnnual banned-substance review: analytical approaches in human sports drug testing.
The timely update of the list of prohibited substances and methods of doping (as issued by the World Anti-Doping Agency) is an essential aspect of international anti-doping efforts and represents consensual agreement by expert panels regarding substances and the methods of performance manipulation in sports. The annual banned-substance review for human doping controls critically summarizes recent innovations in analytical approaches; its purpose is to improve the quality of doping controls by reporting emerging and advancing methods that focus on detecting known and recently outlawed substances. This review surveys new and/or enhanced procedures and techniques of doping analysis together with information relevant to doping control that has been published in the literature between October 2009 and September 2010.

Comparative StudyRapid detection and identification of counterfeit and [corrected] adulterated products of synthetic phosphodiesterase type-5 inhibitors with an atmospheric solids analysis probe.
The market success of the three approved synthetic phosphodiesterase type-5 (PDE-5) inhibitors for the treatment of erectile dysfunction has led to an explosion in counterfeit versions of these drugs. In parallel a large market has developed for herbal products claimed to be natural alternatives to these synthetic drugs. The herbal products are heavily advertised on the internet and are freely available to purchase without prescription. ⋯ The physical appearance of the pills resembled the pills from the original manufacturer but contained the wrong active pharmaceutical ingredient (API). Detecting adulteration for five herbal supplements marketed as natural alternatives to PDE-5 inhibitors was also possible using the ASAP. Three types of adulteration were found in the five samples: adulteration with tadalafil or sildenafil, mixed adulteration (tadalafil and sildenafil), and adulteration with analogues of these drugs.
