The mechanism of antidepressant action of the drug is based on the inhibition of reverse neuronal seizure of dopamine, norepinephrine and serotonin. It is an antagonist of muscarinic cholinergic receptors, has antiadrenergic and antihistaminic properties, is effective in bedwetting. Has a central analgesic effect, anti-bulimic and antiulcer action. For full manifestation of antidepressant action, it takes 2-4 weeks.


Bioavailability of Amitriptyline when administered parenterally is 30-60%, the bioavailability of nortriptyline, which is its active metabolite - 46-70%. To achieve the maximum concentration in the blood, it takes 2-7.5 hours from the beginning of the intake.
C max in blood plasma - 0.04-0.16 μg / ml. The drug has the ability to pass through the histohematological barriers, including the blood-brain barrier. In tissues accumulates in a greater concentration than in the blood. The connection with plasma proteins is 92-96%.
The drug disintegrates in the liver with the formation of active and inactive metabolites. Half-life from blood plasma: for Amitriptyline - 10-28 hours, for nortriptyline - 16-80 hours. 80% of the drug is excreted by the kidneys, partially excreted together with the bile for several days. It is able to penetrate the placental barrier, in breast milk is found in the same amounts as in plasma.

Delayed urination, increased sweating, movement disorders. Symptoms of heart failure, visual disturbances, increased intraocular pressure, paresis of the ciliary muscle of the eye. Changing the composition of the blood, a violation of potency, a change in libido, bowel obstruction. With prolonged use of the drug, weight gain, increase in the size of the mammary glands (in women and men), hair loss and enlarged lymph nodes.


    Hypersensitivity to the components of the drug;

Interaction with other medicinal products

Amitriptyline is incompatible with antidepressants (MAO inhibitors). Strengthens the depressing effect on the central nervous system while using with anticonvulsant drugs, hypnotics, anesthesia and analgesics. When interacting with anticholinergic drugs and neuroleptics, an increase in body temperature, the development of intestinal obstruction, is possible. Simultaneous use with catecholamines and other adrenostimulators can cause heart rhythm disturbances and the development of severe arterial hypertension. It is able to reduce the effect of sympatholytic and vasoconstrictive drugs. Simultaneous use of Amitriptyline and cimetidine, due to an increase in the concentration of antidepressant in the blood plasma, leads to the development of toxic effects, barbiturates and carbamazepine reduce its concentration. Oral estrogen-containing contraceptives increase the bioavailability of the drug, quinidine slows its metabolism. When combined with acetal dehydrogenase inhibitors, delirium may develop (a mental disorder that proceeds with a violation of consciousness). Interaction with Probucol strengthens cardiac arrhythmia. Against the background of taking Amitriptyline may increase the depression, provoked by glucocorticoid drugs. Joint use with drugs used in the treatment of thyrotoxicosis, increases the risk of agranulocytosis. With great caution, use the drug with Baclofen and Digitalis.
