Acetylcholinesterase Inhibition: Galantamine Hydrobromide primarily works by inhibiting acetylcholinesterase, an enzyme responsible for breaking down acetylcholine in the brain. By inhibiting this enzyme, galantamine increases the levels of acetylcholine, which is essential for learning and memory processes.
Modulation of Nicotinic Receptors: Galantamine also modulates nicotinic acetylcholine receptors, thereby enhancing the cholinergic neurotransmission further and improving cognitive functions.
