Syria’s Olympic 400m hurdler Ghfran Almouhamad has been disqualified from the Olympics after testing positive for methylhexaneamine, according to the BBC.
Almouhamad, 23, finished eighth in the second heat of the first round of the event on 5 August.
Although intended to be used as a nasal decongestant, methylhexaneamine has been marketed as a dietary supplement in combination with caffeine and other ingredients, under trade names such as Geranamine and Floradrene, to be used as a general purpose stimulant.
Almouhamad was just one of four women in the 10-member Syrian team.
It is the seventh positive case reported by the IOC since it started its testing program for the London games on 16 July. She is only the second athlete who competed in the Games who has been sanctioned for doping. The others were caught before competing.
American judoka Nick Delpopolo was expelled after testing positive for marijuana during competition, which he said he unintentionally consumed in something he ate.
