    Iga Świątek Suspended After Positive Test for Prohibited Substance Trimetazidine

    Polish tennis star and former world number one Iga Świątek has been suspended for one month following a positive test for trimetazidine (TMZ), a banned substance often used to treat ischemic heart disease. TMZ, which enhances blood circulation and protects heart cells, has been on the World Anti-Doping Agency (WADA) list of prohibited substances since 2014 due to its potential to enhance physical performance.

    Świątek’s test was conducted on August 12 during an out-of-competition screening shortly before the WTA Cincinnati tournament. According to the International Tennis Integrity Agency (ITIA), the trace amounts of TMZ in her system originated from contaminated over-the-counter melatonin, which she used to manage jet lag and sleep issues.

    The ITIA’s investigation, supported by interviews and laboratory analyses, concluded that Świątek unintentionally ingested the banned substance. Her minimal violation and lack of intent were pivotal in the decision to limit the suspension to one month.

    This case highlights the challenges athletes face with inadvertent doping. Other high-profile incidents involving TMZ include those of Chinese swimmer Sun Yang and Russian figure skater Kamila Valieva, who faced suspensions under different circumstances.

    Świątek expressed her commitment to maintaining fair play in sport, and she plans to resume competition following the end of her suspension.
