Solution for intramuscular and intravenous administration.
5 ampoules of 1 ml.
Chloropyramine has antiallergic and antipruritic effects.
Chloropyramine is a blocker of H1 receptors. By chemical structure, it refers to ethylenediamine derivatives. Chloropyramine selectively inhibits histamine H1 receptors and reduces capillary permeability. Prevents development and facilitates the course of allergic reactions. It has a sedative and pronounced antipruritic effect. It has a moderate peripheral anticholinergic and antispasmodic activity and antiemetic effect.
Absorption: Blood concentration reaches a maximum for 2 hours and remains at the therapeutic level for 4 to 6 hours.
Distribution: Evenly distributed in the body, crosses the blood-brain barrier. The connection of chloropyramine with plasma proteins is 7.9%. The peak binding was observed at pM 6.8-7.4.
Excretion: Metabolized in the liver, excreted mainly through the kidneys with urine in the form of metabolites.
Allergic diseases, including:
pollinosis (hay fever),
Individual hypersensitivity to the drug Chloropyramine.
Concomitant use of monoamine oxidase inhibitors.
Pregnancy and lactation.
Peptic ulcer in the acute stage.
The drug should be prescribed with caution to elderly patients, with insufficient liver function and / or heart disease, with peptic ulcer of the gastrointestinal tract, while taking medications that inhibit the central nervous system.
Alcoholic beverages are not allowed during treatment.
Taking the drug overnight can increase the symptoms of reflux esophagitis.
If, during prolonged use of the drug, an unreasonable increase in body temperature, laryngitis, pallor of the skin, jaundice is observed, the formation of ulcers of the oral mucosa, the appearance of hematomas, unusual and difficult to stop bleeding, you must consult a doctor, since prolonged therapy with antihistamines can lead to impaired hematopoiesis.
Antihistamines can distort the reaction when staging skin allergy tests, so the drug should be discontinued a few days before the planned test.
When combined with ototoxic drugs, chloropyramine may mask early manifestations of ototoxicity.
Influence on the ability to drive vehicles and operate machinery
Patients using chloropyramine are advised to refrain from driving vehicles, working with machinery, as well as from other activities, requiring increased concentration of attention and speed of psychomotor reactions.
1 ml of solution for intramuscular and intravenous administration contains: active ingredient: chloropyramine hydrochloride 20 mg
excipient: water for injection
Dosage and Administration
Intramuscularly or intravenously.
Adults are prescribed 20-40 mg per day (contents of 1-2 ampoules).
Treatment in children begins with a dose of 5 mg (0.25 ml). In the future, the dose increase is limited mainly by the appearance of side effects.

Allergic reactions to the drug.
Enhances the effects of drugs for general anesthesia, hypnotics, sedatives, tranquilizers, m-anticholinergics, opioid analgesics, local anesthetics.
Tricyclic antidepressants and MAO inhibitors enhance the m-anticholinergic and inhibitory effect on the central nervous system.
Caffeine and phenamine reduce CNS depressant effects.
Concomitant use with ethanol is not recommended (risk of severe CNS depression).
Symptoms: in children – excitement, anxiety, hallucinations, athetosis, ataxia, convulsions, mydriasis, immobility of the pupils, hyperemia of the skin, hyperthermia then – collapse, coma. In adults – depression (inhibition, depression) or excitation of the central nervous system (psychomotor excitation), very rarely-hallucinations, coordination disorder, pupil dilation and lack of reaction to light, dry mouth, hyperthermia and hyperemia of the skin, convulsions, convulsions. cases – coma.
Treatment: symptomatic therapy (including prescription of antiepileptic drugs, caffeine, phenamine), resuscitation, artificial lung ventilation – according to the indications. There is no specific antidote.
