How Galantamine Works

Galantamine works by increasing the levels of a neurotransmitter called acetylcholine in the brain. This is achieved by inhibiting an enzyme called acetylcholinesterase, which breaks down acetylcholine.

By enhancing acetylcholine levels, Galantamine helps improve communication between nerve cells, which can aid in cognitive function and memory.
