Results for: Trimetazidine (TMZ)

Twenty-three Chinese swimmers failed drug tests for trimetazidine (TMZ) in the lead-up to the Tokyo Olympics in 2021, but were still allowed to compete. The World Anti-Doping Agency (Wada) knew about the failed tests and accepted China’s explanation that the tests were contaminated. However, drugs officials in the United States have accused Wada of a cover-up. There is no evidence of systemic state-run doping in China, but the incident has raised questions about the integrity of the Olympic Games and the effectiveness of drug testing.

The World Anti-Doping Agency (WADA) has defended its decision to clear 23 Chinese swimmers who tested positive for a banned heart medication before the 2021 Tokyo Olympics, citing a thorough investigation and scientific evidence. The agency acknowledged questions raised by media reports but maintained that the swimmers’ samples were contaminated, as accepted by Chinese authorities. WADA emphasized its commitment to fair play and its pursuit of justice in anti-doping cases.
