A spokesperson for Bradley Wiggins does not believe medical records leaked as part of the Russian cyber hack on the World Anti-Doping Agency (WADA) do anything to discredit the cyclist.
WADA announced late on Wednesday a second batch of information from 25 athletes had been released by 'Fancy Bears', with five-time Olympic gold medallist Wiggins and former Team Sky team-mate Chris Froome included.
The latest leak appears to show when therapeutic use exemptions (TUEs) - whereby competitors are granted permission to take performance-enhancing substances for medical reasons - have been provided.
The documents allege that a number of TUEs for salbutamol, a medication to open up medium and large airways in the lungs, dating back to June 2008 were issued to Wiggins.
Furthermore, the Brit was supposedly granted permission to take asthma medications formoterol and budesonide in December 2008, while triamcinolone acetonide was approved due to a pollen allergy.
There is no suggestion that any of the athletes named have done anything wrong or broken any rules.
A spokesperson for Wiggins said: "There's nothing new here. Everyone knows Brad suffers from asthma; his medical treatment is BC [British Cycling] and UCI approved and like all Team GB athletes he follows WADA regulations to the letter.
"The leak of these records is an attempt to undermine the credibility of WADA and that's something for them to deal with."
Froome had previously spoken about his TUEs and felt vindicated by what the leaked information appeared to show.
He said in a statement: "I've openly discussed my TUEs with the media and have no issues with the leak which only confirms my statements.
"In nine years as a professional I've twice required a TUE for exacerbated asthma, the last time was in 2014."
WADA director general Olivier Niggli apologised to the 29 athletes who have had their information released and strongly condemned the attacks.
