1. Determination of Amphetamine, Amfepramone and Fenproporex in Urine Samples by HPLC-DAD: Application to a Population of Brazilian Truck Drivers
Commercially available immunoassay tests are designed to detect the presence of amphetamine/methamphetamine or methylenodioxyamphetamines. However, it is known that Brazilian truck drivers also report the use of other illicit amphetamines, such as amfepramone and fenproporex. Thus, a method was developed and validated in order to quantify amphetamine-type st
