For the treatment of depression, anxiety, diabetic neuropathy, and migraine prophylaxis.
Mode of Action
Amitriptyline is metabolized to nortriptyline which inhibits the reuptake of norepinephrine and serotonin almost equally. Amitriptyline inhibits the membrane pump mechanism responsible for uptake of norepinephrine and serotonin in adrenergic and serotonergic neurons.
Rapidly and well absorbed following oral administration (bioavailability is 30-60% due to first pass metabolism). Peak plasma concentrations occur 2-12 hours following oral or intramuscular administration. Very highly protein bound (90% or more) in plasma and tissues
