Abstract

This article reviews the mechanisms of action of Actovegin in the context of its preclinical effects and new concepts in the pharmacological treatment of neurological disorders. Actovegin is an ultrafiltrate of calf blood, composed of more than 200 biological substances. The drug is used for a broad spectrum of diseases, including disturbances of peripheral and cerebral blood circulation, burns, impaired wound healing, radiation-induced damage and diabetic polyneuropathy. Actovegin is composed of small molecules present under normal physiological conditions, therefore pharmacokinetic and pharmacodynamic studies to determine its active substance are not feasible. Preclinical data have revealed that it improves metabolic balance by increasing glucose uptake and improving oxygen uptake under conditions of ischemia. Actovegin also resists the effects of gamma-irradiation and stimulates wound healing. More recent preclinical studies have suggested that anti-oxidative and anti-apoptotic mechanisms of action specifically underlie the neuroprotective properties of Actovegin. The drug has been found to exert these beneficial effects experimentally, in primary rat hippocampal neurons and in an STZ-rat model of diabetic polyneuropathy, while also providing evidence that it positively affects the functional recovery of neurons. Latest data suggest that Actovegin also has a positive influence on the NF-κB pathway, but many molecular and cellular pathways remain unexplored. In particular, Actovegin's influence on neuroplasticity, neurogenesis and neurotrophicity are questions that ideally should be answered by future research. Nevertheless, it is clear that the multifactorial and complex nature of Actovegin underlies its pleiotropic neuroprotective mechanisms of action and positive effect on clinical outcomes.
