With the simultaneous use of the drug Aminazin ® with other drugs that have a depressing effect on the central nervous system (funds for general anesthesia, narcotic analgesics, ethanol (alcohol) and containing drugs, barbiturates, tranquilizers, etc.), it is possible to increase the depression of the central nervous system, as well as respiratory depression.
Barbiturates can reduce the concentration of chlorpromazine in the blood serum. Undesirable long-term combination with analgesics and antipyretics - it is possible the development of hyperthermia.
The administration of chlorpromazine together with tricyclic antidepressants, maprotiline or monoamine oxidase (MAO) inhibitors increases the risk of neuroleptic malignant syndrome;
The phenothiazine derivatives are antagonists of the action of epinephrine and other simporomimetics and antiepileptic drugs (lowering the threshold of convulsive alertness).
When using chlorpromazine in combination with drugs for the treatment of hyperthyroidism, the risk of developing agranulocytosis increases.
When chlorpromazine is used in combination with drugs that cause extrapyramidal reactions, it is possible to increase the incidence and severity of extrapyramidal disorders. The phenothiazine derivatives increase the hypotensive effect of agents for anesthesia, blockers of "slow" calcium channels and other antihypertensive agents and trazodone. Chlorpromazine reduces the hypotensive effect of neuronal adrenoblockers, such as guanethidine, the effects of amphetamines, clonidine.
With the simultaneous use of chlorpromazine and angiotensin-converting enzyme (ACE) inhibitors, severe orthostatic hypotension occurs.
The simultaneous use of beta-blockers and chlorpromazine increases the risk of arterial hypotension, including orthostatic, due to the summation of the vasodilating effect of chlorpromazine and a decrease in cardiac output caused by beta-blockers.
The simultaneous use of beta-blockers and chlorpromazine increases the risk of developing irreversible retinopathy, tardive dyskinesia.
Simultaneous use of chlorpromazine with antiarrhythmic drugs of Class 1a and III, beta blockers, some calcium channel blockers, LS digitalis, pilocarpine, anticholinesterase drugs may be accompanied by bradycardia and an increased risk of ventricular arrhythmia, including pirouette. When these drugs are combined with chlorpromazine, ECG monitoring is recommended.
Simultaneous use of chlorpromazine with nitrates increases the risk of orthostatic hypotension due to an increased vasodilator effect.
The simultaneous use of chlorpromazine with thiazide diuretics contributes to the intensification of hyponatremia.
The simultaneous use of chlorpromazine with bromocriptine increases the concentration of prolactin in the plasma and prevents the action of bromocriptine.
Simultaneous use with antimuscarinic drugs may aggravate the development of anticholinergic side effects (urinary retention, acute glaucoma attack provocation, dry mouth, constipation, etc.). Anticholinergic properties have different drugs atropine, tricyclic antidepressants, H1-histamine blockers, antimuscarinic, antiparkinsonian anticholinergic antispasmodics, dysopiramid, phenothiazine antipsychotics and clozapine.
When chlorpromazine is used in combination with ephedrine, the vasoconstrictive effect of ephedrine may be reduced.
When treating with the drug Aminazin®, the introduction of epinephrine should be avoided, since the effect of epinephrine may be distorted, which can lead to a drop in blood pressure. The use of epinephrine in case of an overdose is not allowed.
Chlorpromazine reduces the antiparkinsonian effect of levodopa (due to the blockade of dopamine receptors).
Chlorpromazine has a moderate anticholinergic activity, which can be increased by other anticholinergic drugs. Aminazine® also enhances the anticholinergic effects of other drugs, while its own antipsychotic effect may decrease.
With the simultaneous use of chlorpromazine with a prochlorperazine related to the chemical structure, a prolonged loss of consciousness may occur.
Antacids, anti-Parkinsonian drugs and lithium salts can reduce the absorption of chlorpromazine. Antacids should not be used two hours before and after using the drug Aminazine ©.
Chlorpromazine causes increased renal excretion of lithium, in addition, the combination with lithium drugs increases the risk of extrapyramidal complications.
Chlorpromazine can mask some manifestations of ototoxicity (tinnitus, dizziness) of drugs that have ototoxic effects (for example, antibiotics with ototoxic effect).
Other hepatotoxic drugs increase the risk of hepatotoxicity.
Means that inhibit bone marrow hematopoies increase the risk of myelosuppression. With the simultaneous use of chlorpromazine with antimalarial drugs, the concentration of chlorpromazine in the blood plasma increases with the risk of developing toxic effects.
With the simultaneous use of chlorpromazine with cimetidine, a change (increase or decrease) in the concentration of chlorpromazine inblood plasma.
When combined with hypoglycemic preparations chlorpromazine in high doses (100 mg / day) weakens the hypoglycemic effect by reducing the secretion of insulin and increasing blood glucose (see section "Special instructions").
