Galantamine belongs to the tertiary alkaloids of the group of indirect parasympathomimetics. It is a selective, competitive and reversible inhibitor of the enzyme acetylcholinesterase. It causes an increase in the level of acetylcholine in the central nervous system. In addition to its action as a reversible inhibitor of acetylcholinesterase, it acts as an allosteric potentiating ligand of the most common nicotinic acetylcholine receptors of the alpha 4/beta 2 subtype in the central nervous system, which directly stimulates nicotinic receptors. It also increases the sensitivity of postsynaptic receptor membranes to acetylcholine. Galantamine penetrates the blood-brain barrier, facilitates the conduction of impulses in the CNS and accelerates the processes of excitation. It increases the activity of the cholinergic system, resulting in improved cognitive functions.
