Amateur para-cyclist Bahram Soleyman of Iran has been banned by the Iranian National Anti Doping Organization (NADO) after testing positive for the substance Triamterene.

Triamterene is a diuretic prescribed to treat edema (fluid retention) typically associated with hypertension and other cardiovascular conditions. It causes the kidneys to eliminate excess water and sodium from the body via urine, but without loosing important potassium electrolytes.

Athletes take banned diuretics like Triamterene to excrete water rapidly to reduce body weight and mask the presence of other banned substances. Because of widespread abuse by athletes, diuretics are named on the World Anti-Doping Agency’s (WADA) list of prohibited substances for both in-competition and out-of-competition use.

However, WADA permits the therapeutic use of diuretics when athletes and their physicians apply and are approved for a Therapeutic Use Exemption (TUE) based on documented medical treatment records. For diuretics, a TUE is primarily only granted to treat hypertension. 

The most famous cyclist banned for using diuretics is former WorldTour pro Frank Schleck, who tested positive for Xipamide during the 2012 Tour de France and was forced to withdraw from the race. He was subsequently banned from competition for one year.

Bahram Soleyman is ineligible to compete in cycling events for two years, from 2 August 2022 until 2 August 2024.
