Pharmacodynamics

The spectrum of action is attributed to the presence of GABA in the drug structure. The mechanism of action is determined by the direct effect of the Pantocalcin® drug on the GABAB receptor-channel complex. It has neurometabolic, neuroprotective and neurotrophic properties. It increases brain resistance to hypoxia and to effects of toxic substances and it stimulates anabolic processes in neurons. It has the anticonvulsant effect; reduces motor excitability while regulating behavior. The drug increases mental activity and performance capability. It helps normalize the level of GABA in case of the chronic alcohol intoxication and the subsequent abolition of ethanol. It has the analgesic effect. It can inhibit acetylation reactions participating in mechanisms of Novocain and sulfonamides inactivation, due to which the prolongation of the action of the latter is achieved. It causes inhibition of the pathologically increased vesical reflex and the detrusor tonus.

Pharmacokinetics

When taken orally, it is rapidly absorbed from the digestive tract. Tmax in blood plasma is 1 hour. Highest concentrations are in the liver, kidneys, stomach wall, and skin. The drug penetrates through the BBB. It is not metabolized and is excreted unchanged within 48 hours (67.5% of the taken dose - with urine, 28.5% - with feces).

Side effects (rare)
