Galantamine competitively and reversibly inhibits acetylcholinesterase, thereby increasing the concentration and enhancing the action of acetylcholine (Ach). In addition, galantamine is a ligand for nicotinic acetylcholine receptors, which may increase the presynaptic release of Ach and activate postsynaptic receptors. This agent may improve neurocognitive function in mild and moderate Alzheimer' s disease and may reduce abstinence-induced cognitive symptoms that promote smoking relapse."}]
