Pharmacodynamics and pharmacokinetics

The mechanism of action of Thioridazine is based on the ability of the drug to disrupt adrenergic and dopaminergic transmission of nerve impulses, especially in the reticular formation of the brain. The substance eliminates the activating effect on the limbic system and cerebral cortex. The drug provides blocking of m-cholinergic receptors , significantly reducing the activity of the autonomic nervous system.

The chemical compound affects various psychomotor functions, reduces general arousal, mobility, eliminates agitation and the degree of affective tension. The medicine also has a sedative effect, but does not lead to general lethargy and lethargy. It has some antidepressant and activating effects, moderate sedative and anticholinergic. Does not have a cataleptogenic effect, reduces blood pressure .

After taking the tablets, their contents are quickly absorbed in the digestive tract. The maximum concentration is observed after 1-4 hours. The drug quickly overcomes the histohematic barriers, the blood-brain and placental barriers, and is excreted in breast milk. The product has a high degree of bioavailability.

Metabolized in the liver with the participation of the cytochrome CYP2D6 to sulforidazine and mesoridazine (active metabolites). The half-life from the body ranges from 6 to 40 hours. The medicine is excreted through the kidneys, with bile. The mesoridazine metabolite is more active than the substance itself; it has a longer elimination time from the body, but a lower degree of binding to blood proteins.

Side effects of the drug Thioridazine

Common side effects, especially when using a high dose and early in treatment, include drowsiness, sedation, dizziness, nasal congestion, and dry mouth. Dose-dependent orthostatic hypotension is sometimes observed, especially in elderly patients. Other dose-related effects associated with the anticholinergic activity of thioridazine include disturbances of accommodation, tachycardia, constipation, and urinary retention or incontinence. In some patients, thioridazine, even in low doses, can cause a feeling of mental depression, nausea, dizziness, headache, or, conversely, paradoxical effects of agitation, agitation or insomnia. In some cases, neuroleptic malignant syndrome (muscle rigidity, hyperthermia, mental status disorders, autonomic lability) was observed, requiring immediate discontinuation of thioridazine. When used in high doses, as with other phenothiazines, ECG changes of the repolarization type are described (lengthening of the Q-T , flattening of the T and appearance of the U ). These changes are most likely due to a decrease in potassium concentration in the blood. Like all phenothiazines, thioridazine can in rare cases provoke arrhythmias. Cases of sudden unexplained death, possibly due to arrhythmia or cardiac arrest, have been reported among patients receiving tricyclic antipsychotics, including thioridazine. When prescribing high (neuroleptic) doses of thioridazine, extrapyramidal symptoms are possible; when using low (anxiolytic) doses they are practically not observed. There have been reports of cases of pigmentary retinopathy during long-term treatment with thioridazine, mainly when taking more than 800 mg of thioridazine per day. Antipsychotic drugs such as thioridazine can cause hyperprolactinemia, leading to galactorrhea, menstrual irregularities, erectile dysfunction (weakness of erection or priapism) and ejaculation, and sometimes weight gain and edema. These effects can be prevented by reducing the dose of thioridazine. Rare cases of leukopenia and agranulocytosis, especially in the first months of treatment, photosensitivity, allergic rash, jaundice, hepatitis and liver dysfunction have been described.

Interaction

Simultaneous use with drugs that depress the central nervous system and ethyl alcohol leads to increased sedative properties of the drug.

The medicine reduces the effectiveness of anticonvulsants and cimetidine .

Thioridazine enhances the effect of anticholinergics and sympathomimetics.

The combined use of the drug with drugs that lower blood pressure leads to an even greater decrease in blood pressure and the development of orthostatic hypotension .

When combined with appetite suppressants other than fenfluramine , this substance significantly reduces their effectiveness.

Simultaneous use of the drug with anticoagulants leads to a decrease in their effectiveness; with antithyroid drugs – to the development of agranulocytosis ; with beta-blockers - leads to increased hypotensive effect. The drug increases the risk of arrhythmias , tardive dyskinesia , and retinopathy .

Hypoglycemic agents lose their effectiveness when used with Thioridazine.

The combined use of the drug with amphetamine leads to a mutual weakening of the properties of both drugs.

With the simultaneous use of this substance and apomorphine , the emetic effect of the latter is reduced and the sedative effect is enhanced.

The medicine causes an increase in the concentration of prolactin in the blood and reduces the effectiveness of bromocriptine .

The drug can reduce the effectiveness of levodopa and guanethidine .

The combined use of the drug with probucol , cisapride , astemizole , disopyramide , pimozide , erythromycin , procainamide leads to prolongation of the QT interval and the development of ventricular tachycardia .

Thioridazine reduces the rate of absorption of lithium salts from the digestive tract and increases the rate of excretion of lithium ions from the body. The drug is also able to mask some signs of acute lithium intoxication, vomiting, and nausea.

hyponatremia increases ; with trazodone – its concentration in the blood increases.

Drug interactions Thioridazine

Thioridazine, like other phenothiazines, can enhance the inhibitory effect on the central nervous system of alcohol, central nervous system depressants and antihistamines, the M-anticholinergic effect of anticholinergics and the inhibitory effect of quinidine derivatives on the myocardium. Thioridazine can reduce the severity of the antiparkinsonian effect of levodopa, reduce the seizure threshold in patients with epilepsy (which may require changing the dose of anticonvulsants), and reduce the pressor effect of adrenergic vasoconstrictors. MAO inhibitors may enhance or prolong the sedative and antimuscarinic effects of phenothiazines. Concomitant use of lithium preparations contributes to the development of extrapyramidal symptoms and increased neurotoxic properties of thioridazine. Taking beta-adrenergic receptor blockers may cause an increase in the concentration of thioridazine in the blood plasma. The absorption of thioridazine may be impaired by antacids and antidiarrheal drugs.
