October 18/10 16:07 pm - WADA Releases 2011 Prohibited List

Posted by Editoress on 10/18/10

The World Anti-Doping Agency (WADA) has released the 2011 Prohibited List and updated the International Standard for Therapeutic Use Exemptions. It comes into effect January 1, 2011.

The major revisions include:

• A new category called Non-Approved Substances (S0) effectively bans drugs under pre-clinical or clinical development, as well as discontinued drugs.

• Under Peptide Hormones, Growth Factors and Related Substances (S2), WADA added HIF stabilizers as an example of EPO-like substances, which are banned for having a similar chemical structure or similar biological effect as EPO.

• In the same category, intra-muscular administration of Platelet-Derived Preparations, otherwise known as PRP or blood spinning, is no longer prohibited.

• The last paragraph of section Diuretics and Other Masking Agents (S5) explains that if a threshold substance is detected at a sub-threshold concentration in the presence of a diuretic or other masking agent, a TUE is required for both substances.

• The definition of Cannabinoids (S8) is reworded to clarify that all cannabimimetics are prohibited in-competition.

• Alcohol (P1) is no longer prohibited in modern pentathlon for disciplines involving shooting.

• Beta-blockers (P2) are no longer prohibited in gymnastics, but are now prohibited in darts. The list clarifies that beta-blockers have always been prohibited in skeleton in addition to bobsleigh.

• Methods that consist of sequentially withdrawing, manipulating and reinfusing whole blood into the circulation are now part of the category of Chemical and Physical Manipulation (M2).

• Starting in 2011, athletes will no longer be obligated to file a Declaration of Use - currently this is required for some beta-2 agonists (S3), specific routes of administration of glucocorticosteroids (S9), and PRPs. This change is reflected in the 2011 International Standard for Therapeutic Use Exemptions. Athletes should continue to declare all medications and supplements verbally to the doping control officer if selected for doping control.
