Description
O Krug and colleagues investigate how two modafinil analogues, flmodafinil and fladrafinil, are broken down and cleared from the body for sports drug testing. Both drugs stimulate the central nervous system and have grown popular outside medicine for claimed cognitive gains.
As class S6 stimulants on the World Anti-Doping Agency list, both are banned in competition. Six volunteers took 20 milligrams of one drug or the other, and urine and blood samples were tracked for parent drugs and metabolites. Anti-doping labs get elimination profiles for catching these analogues in athletes' samples.
