Drug meldonium has caught world wide attention due to the failure of drug test by Russian tennis player Maria Sharaporva.
Meldonium manufactured by Grindeks, a Latvian pharmaceutical company, used to treat ischemia, a condition in which body tissues are deprived of blood supply, causing a shortage of oxygen and glucose was banned by world anti dopsing agency(WADA)
Inventor of melodinum Ivar kalvins made it for the use of soldiers operating in mountains with lack of adequate supply of oxygen
But it was banned because it aids oxygen uptake and endurance, and several athletes have been caught using it. It was previously monitored by the World Anti-Doping Agency (WADA), and added to its list of banned substances on September 16, 2015 — effective starting January 1, 2016. WADA classifies the drug as a “metabolic modulator”, like insulin.
