The mechanism of the antidepressant effect of the drug is based on the inhibition of the reverse neuronal uptake of dopamine, norepinephrine and serotonin. It is an antagonist of muscarinic cholinergic receptors, has anti-adrenergic and antihistamine properties, and is effective in bedtime incontinence. It has a central analgesic effect, anti-bolemic and anti-ulcer effects. For the full manifestation of the antidepressant action takes 2-4 weeks.


The bioavailability of Amitriptyline with parenteral administration is 30-60%, the bioavailability of nortriptyline, which is its active metabolite, is 46-70%. To achieve the maximum concentration in the blood takes 2-7.5 hours from the start.

C max in the blood plasma - 0.04-0.16 µg / ml. The drug has the ability to pass through histohematogenous barriers, including the blood-brain barrier. In tissues it accumulates in greater concentration than in blood. Communication with plasma proteins is 92-96%.

The drug disintegrates in the liver with the formation of active and inactive metabolites. Plasma elimination half-life: for amitriptyline - 10-28 hours, for nortriptyline - 16-80 hours. 80% of the drug is excreted by the kidneys, partially excreted along with the bile within a few days. Able to penetrate the placental barrier, in breast milk is found in the same quantities as in the plasma.

  • Anxiety-depressive states;
  • Unspecified organic psychosis (involutional, neurotic, endogenous, reactive brain damage);
  • Nervous bulimia;
  • Behavioral disorders;
  • Drug psychosis;
  • Migraine prophylaxis;
  • Inorganic enuresis;
  • Chronic neurogenic pain syndrome;
  • Mixed emotional disorders.

Dry mouth, a violation of taste, nausea, vomiting, diarrhea, constipation and other disorders of the digestive tract. Skin allergic reactions, dizziness, weakness, sleep disorders. Delay urination, increased sweating, movement disorders. Symptoms of heart failure, visual impairment, increased intraocular pressure, paresis of the ciliary muscle of the eye. Changes in the composition of the blood, impaired potency, changes in libido, intestinal obstruction. With prolonged use of the drug weight gain, an increase in the size of the mammary glands (in women and men), hair loss and an increase in lymph nodes.

Interaction with other drugs

Amitriptyline is incompatible with antidepressants (MAO inhibitors). Strengthens the inhibitory effect on the central nervous system while using it with anticonvulsants, hypnotics, anesthetics and analgesics. When interacting with anticholinergic drugs and neuroleptics, an increase in body temperature, development of intestinal obstruction is possible. Simultaneous use with catecholamines and other adrenergic stimulants can cause heart rhythm disturbances and the development of severe arterial hypertension. Able to reduce the effect of sympatholytics and vasoconstrictor drugs. The simultaneous use of Amitriptyline and Cimetidine, due to the increase in plasma concentration of the antidepressant, 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 down its metabolism. When used together with acetaldehyde dehydrogenase inhibitors, it is possible to develop delirium (mental disorder that occurs with impaired consciousness). Interaction with Probukol strengthens cardiac arrhythmia. While taking Amitriptyline, it is possible to increase the depression provoked by glucocorticoid drugs. Combined use with drugs used in the treatment of thyrotoxicosis increases the risk of agranulocytosis. With great caution should use the drug when using baclofen and digitalis.

Leave your feedback

nmorin83: This medicine makes me extremely sleepy when I take it and the next day I'm exhausted. Like I just want to sleep all day. I tried just taking as needed (as prescribed) but it's for my foot and since I'm on my feet a lot I need it more frequently. Thankful I won't need this for long (having surgery to fix the problem), because I am so so sleepy.

Rosza Thorns: It makes me extremely drowsy all day and my stomach has been upset since the start of this medication. I also experienced extreme nausea... This I an addictive med!

Pete Moyer: Took some for the first time last week. Took it with food and plenty of water. After 10 minutes started to feel nauseous and lightheaded. I was at work and work in a warehouse so I tried to make it to the bathroom. Immediately passed out and busted my jaw on our concrete floor. I’ve needed six stitches and a lot of dental work (two missing teeth now) because I took this drug without laying down first.

Robert Nordeen: Ive been taking it for months. Makes the pain go away. But it affect your attention to detail. I was in a meeting and a paper was placed in front of me. Next thing I knew I was looking for a paper in my book. Then I asked the instructor for a new copy. The assistant said, you have one in front of you. I'm addicted to it and there are the bad effects that they don't tell you about. Another doc on u tube said, don't take it with asthma. I have asthma. I quit. Really! I'm keeping my mind.

Lillie Konttinen: I found it to make me very drowsy and sleepy. I almost feel high when I’m on it and hate it. I don’t like the feeling and can’t work on it when I need it
