What is Meldonium?

In March 2016, Meldonium rose to notoriety when five-time tennis grand slam winner Maria Sharapova announced that she had failed a drugs test following use of the substance. Meldonium (also known as mildronate) originated in Latvia and was originally produced for use as an animal growth promoting agent in the late 1970s (1,2).

When applied in human clinical trials it was observed that its’ beneficial effects are anti-ischemic; meaning that it can allow a greater amount of blood to flow through the vessels to supply the body’s organs and tissues. The types of conditions that this substance can help with include; neurodegenerative disorders, immunomodulator and bronchopulmonary diseases, (3,4) in particular it can help with chronic heart disease, angina and has been used to treat stroke victims.

This substance is banned in several countries including the UK, USA and Australia. Meldonium was added to the WADA prohibited list on January 1st 2016 after being on the WADA monitoring list in 2015, citing that it was due to its performance enhancing abilities.

Why has Meldonium been used in sport?

In sport it has been found that the benefits of this substance include increased working capacity, increased endurance capacity and protection against stress. It has been noted that many athletes have used it in the past before it was banned by WADA (5,6).
