Aichi-Nagoya, Japan: Thailand women’s singles player Pitchamon Opatniputh has been provisionally suspended after an out-of-competition doping control produced an adverse analytical finding for furosemide, according to the International Testing Agency.
The development comes one day before Thailand is scheduled to face China in the women’s team quarterfinals at the 2026 Aichi-Nagoya Asian Games.
ITA Reports Adverse Analytical Finding for Furosemide
The International Testing Agency said Pitchamon’s sample returned an adverse analytical finding for furosemide, a substance prohibited under the World Anti-Doping Agency’s rules.
The sample was collected during an out-of-competition doping control conducted by the ITA on September 17 in Nagoya, Japan.
“The analysis of the athlete’s sample returned an adverse analytical finding for the specified prohibited substance furosemide,” the ITA said.
What Is Furosemide?
Furosemide is listed on the WADA Prohibited List under category S5, which covers diuretics and masking agents.
The substance is prohibited at all times, including both in competition and out of competition.
Furosemide is medically used as a diuretic to remove excess fluid from the body and can also cause rapid water-weight loss.
Pitchamon Suspended With Immediate Effect
The ITA said Pitchamon has been notified of the case and is subject to a provisional suspension with immediate effect while the proceedings continue.
The suspension means she is not permitted to compete, train, coach or take part in other sporting activities during the 2026 Aichi-Nagoya Asian Games while the provisional measure remains in place.
The action is being taken under the World Anti-Doping Code and the Olympic Council of Asia’s anti-doping regulations.
Pitchamon Has Right to Challenge Suspension
The case is not yet a final determination of an anti-doping rule violation.
Pitchamon has the right to challenge the provisional suspension before the Anti-Doping Division of the Court of Arbitration for Sport.
She may also request the analysis of her B sample as part of the anti-doping process.
The ITA said it would not provide further comment while proceedings remain ongoing.
Thailand Faces China in Women’s Team Quarterfinal
The timing creates an immediate challenge for Thailand’s badminton squad ahead of its women’s team quarterfinal against China.
Pitchamon’s unavailability could affect Thailand’s singles options and lineup planning for a tie against one of the strongest teams in Asian badminton.
Further developments will depend on the anti-doping process, including any challenge to the provisional suspension and whether a B-sample analysis is requested.
