Galanthamine extract is specific, competitive and reversible acetylcholinesterase inhibitor. It is also an allosteric modulator at

nicotinic cholinergic receptor sites potentiating cholinergic nicotinic neurotransmission. Both the acetylcholine and nicotine

receptors have been suggested as areas related to cognitive impairment. Galanthamine extract is a product with broad

therapeutic index, allowing "soft" manifestation of its effect with individual dosing depending on the particular case. Now it has

been rapidly introduced in other areas of medicine, i.e. neurology, ophthalmology, gastroenterology, intensive care and

resuscitation, cardiology, physiotherapy.
