Pharmacological properties
Pharmacodynamics
The active component of Propazin - promazine is included in the group of aliphatic phenothiazine derivatives. Its spectrum of action and chemical structure are similar to chlorpromazine (aminazine), but promazine is less toxic and less active.
The mechanism of antipsychotic action is due to the blocking of postsynaptic mesolimbic dopaminergic receptors in the brain.
Promazin has sedative and antipsychotic efficacy, inferior in strength to chlorpromazine, reduces physical activity, has a hypothermic, antiemetic and hypotensive effect. Its peripheral adrenergic and anticholinergic action is similar to chlorpromazine; on antihistaminic properties the drug is superior to chlorpromazine. Propazine has less pronounced side effects than chlorpromazine (in the form of akathisia, lethargy, depression, lethargy, apathy, somatovegetative and extrapyramidal disorders).
With combined use, it increases the intensity and duration of the action of antihypertensive, hypnotic, narcotic, analgesic, antihistamines and alcohol.
Pharmacokinetics
Promazin is well absorbed after oral administration. The maximum concentration of the substance is reached in 2–4 hours.
Binds to proteins at 90%. Metabolism occurs in the liver with the formation of inactive metabolites. The excretion of promazin is carried out mainly by the kidneys.

Instructions for use of Propazin: method and dosage
Propazin tablets should be taken orally after meals.

The maintenance dose of Propazine is 50-150 mg 1-2 times a day.
Teenagers over 12 years old are prescribed 25 mg every 4-6 hours, if necessary, the dose is adjusted.
Weak and malnourished patients, as well as the elderly, usually require a lower starting dose. Further, if the need arises, it is gradually increased.
Side effects
Compared with the frequently used chlorpromazine, promazine is better tolerated and causes fewer side effects.
At the beginning of treatment, there may be: dizziness, drowsiness, accommodation disturbances (blurred vision), sleep disturbances, dry mouth, anorexia, gastralgia, nausea, vomiting, constipation, tachycardia, moderate orthostatic hypotension, nasal congestion, difficulty urinating.
In rare cases, the following side effects of Propazin are noted: allergic reactions, angioedema, cholestatic jaundice, retinopathy pigmentosa, impaired thermoregulation (heat stroke), heart rhythm disturbances, photosensitivity of the skin, weight gain, galactorrhea, decreased sexual potency, priapism, menstrual irregularities, melanosis, agranulocytosis, leukopenia, as well as the phenomenon of delayed reaction to external stimuli, the phenomenon of mental indifference and other changes in the psyche.
With prolonged use, extrapyramidal disorders (akinetic phenomena, autonomic disturbances, hyperkinesia, akathisia, tremor, dyskinesias) are possible, in some cases - convulsions. Antiparkinsonian drugs are used as correctors for these phenomena. Caffeine sodium (subcutaneously 2 ml of a 20% solution) and atropine (subcutaneously 1 ml of a 0.1% solution) help to relieve dyskinesia.
In extremely rare cases, it is possible to develop neuroleptic malignant syndrome.
Overdose
The main symptoms: hyperreflexia or areflexia, blurred vision, cardiotoxic effect (in the form of ventricular fibrillation, tachycardia, changes in the QRS wave, arrhythmia, heart failure, shock, lowering blood pressure, cardiac arrest), neurotoxic effect (including agitation, confusion, convulsions, disorientation, drowsiness, mydriasis, xerostomia, hypothermia or hyperpyrexia, vomiting, stupor or coma, muscle rigidity, respiratory depression, or pulmonary edema).
Therapy: gastric lavage, intake of activated charcoal. Induction of vomiting should be avoided, since in case of overdose disturbances of consciousness and dystonic reactions from the muscles of the neck and head, aspiration of vomit is possible.
Symptomatic therapy:
- arrhythmia: phenytoin (intravenously at a dose of 9-11 mg / kg);
- convulsions: diazepam;
- heart failure: cardiac glycosides;
- marked decrease in blood pressure: intravenous fluid or vasopressor drugs (phenylephrine, norepinephrine). The use of alpha and beta adrenergic agonists such as epinephrine should be avoided;
- parkinsonism: diphenhydramine, diphenyltropine.
Also, in case of an overdose for at least 5 days, control of the function of the cardiovascular and central nervous systems, respiration, measurement of body temperature is shown. Consultation of a psychiatrist is recommended.
Dialysis is ineffective.
special instructions
During treatment, it is necessary to carefully monitor blood pressure and pulse, constantly examine the functions of the kidneys and liver, the picture of peripheral blood, and conduct ophthalmological examinations.
It should be borne in mind that Propazine, used as an antiemetic, can mask vomiting caused by an overdose of other drugs.
Due to the risk of developing photosensitivity during treatment, one should not be exposed to ultraviolet radiation.
During treatment it is forbidden to consume alcoholic beverages

- Tricyclic antidepressants, monoamine oxidase inhibitors, maprotiline: the risk of neuroleptic malignant syndrome increases;
- Anticonvulsants: the seizure threshold is lowered;
- Drugs for the treatment of hyperthyroidism: the risk of agranulocytosis increases;
- Antihypertensive drugs: there is a likelihood of severe orthostatic hypotension;
- Ephedrine: its vasoconstrictor effect is weakened;
- Apomorphine: its emetic effect decreases, the inhibitory effect on the central nervous system increases;
- Means that reduce appetite (with the exception of fenfluramine): their effectiveness decreases;
- Amphetamine, clonidine, guanethidine: their effect may be suppressed;
- Bromocriptine: an increase in the concentration in the blood plasma of prolactin and a decrease in its action is possible;
- Levodopa: its antiparkinsonian effect decreases;
- Antiparkinsonian drugs, antacids, lithium preparations: absorption of promazine is disturbed;
- Prochlorperazine: Prolonged loss of consciousness may occur.
