Actovegin is a highly filtered extract obtained from calf blood which enhances aerobic oxidation in mammals. This improves absorption of glucose and oxygen uptake in tissue, which may enhance physical performance and stamina.
Actovegin made headlines from 2009 to 2011 when Canadian sports doctor Anthony Galea was charged with illegally providing professional athletes with a number of performance-enhancing drugs, including Actovegin. As revealed by later testimony by drivers, it was also regularly used by Lance Armstrong and the members of his U.S. Postal Service Pro Cycling Team on the 2000 Tour de France to enhance their performance. As of 2012, the substance is currently not banned.
Mechanism of action
According to Gulevsky, et al., Actovegin "is highly purified hemodialysate extracted from vealer blood by ultrafiltration." There are less than 5 kDa by molecular weight of organic substances in Actovegin.
Actovegin has been shown to improve the transport of glucose over a plasma membrane and the uptake of oxygen by tissues. This can lead to aerobic oxidation, which provides a cell with access to more energy and potentially enhances its function. Actovegin has large amounts of superoxide dismutase enzymes and magnesium.
Uses and side effects
Nycomed, a Swiss drug company which manufactures Actovegin, claims it can be used for circulation and nutrition disturbances, skin grafting, burns, and wound-healing impairment. Actovegin has also been used as a performance enhancer.
It has been investigated for use in treatment of polyneuropathy in diabetes, and for stroke. One study found that when tissues suffer from hypoxia caused circulation abnormalities, Actovegin helps capillaries improve circulation by enhancing the neogenic mechanism in blood vessels.
Anaphylactic shock has been observed in at least one patient treated with Actovegin.
As of July 2011, the drug was not approved for sale, importation, or use in the United States. It is an unapproved drug in Canada as well, and as of March 2011 it was illegal to import or sell it there.
