Truxal, 25 mg 100 pcs

Truxal is a neuroleptic, a derivative of thioxanthene. It has antipsychotic, pronounced sedative and moderate antidepressant effect.

Pharmacodynamics

The antipsychotic action of Truxal is associated with its blocking effect on dopamine receptors. Blockade of these receptors is also associated with antiemetic and analgesic properties of the drug. Truxal is able to block 5-NT< sub>2 – receptors, α< sub>1 – adrenoreceptors, and H< sub>1 – histamine receptors, which determines its adrenoblocking, hypotensive and antihistamine properties.

Pharmacokinetics

The bioavailability of chlorprotixen with oral administration is about 12%. Chlorprotixen is rapidly absorbed from the intestine, maximum serum concentration is reached after 2 hours. The elimination half-life is about 16 hours. Chlorprotixene penetrates the placental barrier and is excreted in small amounts with breast milk. Metabolites have no neuroleptic activity and are excreted with feces and urine.

How to take, the dosage

Psychosis, including schizophrenia and manic states. Treatment begins with 50 to 100 mg/day, gradually increasing the dose until optimal effect is achieved, usually to 300 mg/day. In isolated cases, the dose may be increased to 1200 mg/day. The maintenance dose is usually 100 to 200 mg/day.

Hangover withdrawal syndrome in alcoholism and drug addiction.
The daily dose, divided into 2 – 3 doses, is 500 mg. The course of treatment usually lasts 7 days. After withdrawal symptoms disappear, the dose is gradually reduced. The maintenance dose of 15 to 45 mg/day helps to stabilize the condition, reducing the risk of another binge.

In elderly patients with hyperactivity, irritability, agitation, confusion, 15 to 90 mg/day is prescribed. The daily dose is usually divided into 3 doses.

In children for correction of behavioral disorders, Truxal is prescribed at the rate of 0.5 to 2 mg per 1 kg of weight.

Depressive states, neuroses, psychosomatic disorders. Truxal may be used for depression, especially combined with anxiety and tension, as an adjunct to antidepressant therapy or alone. Truxal may be prescribed for neurosis and psychosomatic disorders accompanied by anxiety and depressive disorders, up to 90 mg/day. The daily dose is usually divided into 2-3 doses. As taking Truxal is not addictive or addictive, it can be used for a long time.

Interaction

The CNS depressant effect of chlorprotixene may be enhanced with concomitant use of ethanol and ethanol-containing drugs, anesthetics, opioid analgesics, sedatives, hypnotics, neuroleptics.

The anticholinergic effect of chlorprotixen is increased with simultaneous use of anticholinergic, antihistamine and antiparkinsonian agents.

The drug increases the effect of hypotensive drugs.
Simultaneous use of chlorprotixen and adrenaline may lead to arterial hypotension and tachycardia.

The use of chlorprotixen leads to a decrease in the threshold of seizure activity, which requires additional adjustment of the dose of antiepileptic drugs in patients with epilepsy.

The ability of chlorprotixene to block dopamine receptors reduces the effectiveness of levodopa.

Extrapyramid disorders may occur with concomitant use of phenothiazines, metoclopramide, haloperidol, reserpine.

Special Instructions

Truxal should be prescribed with caution in patients with epilepsy, parkinsonism, marked atherosclerosis of cerebral vessels, tendency to collapse, marked cardiovascular and respiratory failure, marked liver and renal function disorders, diabetes, prostatic hypertrophy.
