CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Although the etiology of cognitive impairment in Alzheimer's disease
(AD) is not fully understood, it
has been reported that acetylcholine-producing neurons degenerate in
the brains of patients with
Alzheimer's disease. The degree of this cholinergic loss has been
correlated with degree of cognitive
impairment and density of amyloid plaques (a neuropathological
hallmark of Alzheimer's disease).
Galantamine, a tertiary alkaloid, is a competitive and reversible
inhibitor of acetylcholinesterase. While
the precise mechanism of galantamine's action is unknown, it is
postulated to exert its therapeutic effect
by enhancing cholinergic function. This is accomplished by increasing
the concentration of
acetylcholine through reversible inhibition of its hydrolysis by
cholinesterase. If this mechanism is
correct, galantamine's effect may lessen as the disease process
advances and fewer cholinergic neurons
