Increases resistance of neurons to a hypoxia; strengthening glucose transport to a brain, through a blood-brain barrier; transfers process of disintegration of glucose to energetically more economical, aerobic way; selectively blocks Sa 2+/dependent phosphodiesterase (PDE); increases levels of adenosinemonophosphate (AMF) and a cyclic guanozinmonofosfat (tsGMF) of a brain. Increases concentration of ATP in brain tissues; strengthens exchange of noradrenaline and serotonin of a brain; stimulates the ascending branch of noradrenergichesky system, has antioxidant effect.
Reduces aggregation of thrombocytes and the increased viscosity of blood; increases the deforming ability of erythrocytes and blocks utilization by adenosine erythrocytes; promotes increase in return of oxygen erythrocytes. Strengthens neuroprotective action of adenosine.
Increases a cerebral blood stream; reduces resistance of vessels of a brain without essential change of indicators of system blood circulation (arterial pressure, minute volume, heart rate, the general peripheral resistance). Not only does not render effect of "burglarizing", but also strengthens blood supply, first of all, in ischemic sites of a brain with low, perfusion.

Pharmacokinetics. Therapeutic concentration in plasma - 10-20 ng/ml. At parenteral administration distribution volume - 5.3 l/kg. The elimination half-life makes 4.74-5 h. Easily gets through gistogematichesky barriers (including a blood-brain barrier).
