The menace of counterfeit drugs is no longer a
possibility; it is with us now and growing at a
phenomenal rate, according to organisations such
as the World Health Organisation (WHO) and The
Association of British Pharmaceutical Industry
(ABPI). WHO, for example, estimates that “on
average 10% of the world’s drug supply is
considered counterfeit, adulterated or otherwise
fraudulent, although in some developing
countries it could be as high as 33%.” [1]
Instrumentation using Energy Dispersive X-ray
Diffraction technology is discussed as one
approach to testing drugs for alteration
or substitution.
