Marathoner Lawrence Cherono has been provisionally suspended, the 2019 Chicago Marathon champion tested positive for a banned Trimetazidine, the Athletics Integrity Unit (AIU) has announced.
Trimetazidine, an injectable drug, is used for treating heart-related conditions like angina. It helps metabolize fatty acids, which helps the body to use oxygen. The drug allows for more blood flow to your heart and limits quick changes in your blood pressure. This can help lessen chest pain from blocked blood vessels and it is on the ban list in athletics.
