Pharmacodynamics
Chloropyramine, a chlorinated analog of tripelenamine (pyribenzamine), is a first-generation antihistamine drug belonging to the group of ethylenediamine antihistamines.
A blocker of H1-histamine receptors, it has antihistamine and m-cholin-blocking effects. This drug also acts on smooth muscles, on capillary permeability and on the central nervous system (CNS).
When taken orally, the effect occurs as early as 15-30 minutes, the maximum effect develops within 1 hour and lasts for about 3-6 hours.
Pharmacokinetics
Intake
In oral administration, it is almost completely absorbed from the gastrointestinal tract (GIT). The therapeutic effect of chloropyramine develops within 15-30 minutes after oral administration, reaches its maximum within the first hour after administration and lasts for at least 3-6 hours.
Distribution
It is well distributed in the body, including the CNS.
Metabolism
Intensively metabolized in the liver.
Elimination
Extracted mainly by the kidneys as metabolites.
Particular patient populations
Children and adolescents
The drug is eliminated faster in children than in adult patients.
Patients with impaired liver function
In patients with impaired liver function, the metabolism of chloropyramine is decreased, so the dose of the drug may be reduced.
Patients with impaired renal function
In patients with impaired renal function, the excretion of chloropyramine is decreased, so the dose of the drug may be reduced.
Indications
Urticaria, serum sickness, seasonal and year-round allergic rhinitis, allergic conjunctivitis, contact dermatitis, skin itching, acute and chronic eczema, atopic dermatitis, food and drug allergies, insect bite allergies.
Active ingredient
Chloropyramine

Special patient groups
Elderly patients and patients with significant weight deficit
Use of chloropyramine requires extreme caution because in these patients antihistamines are more likely to cause side effects (dizziness, drowsiness, drop in blood pressure (BP)).
Patients with impaired liver function
Dose reduction may be required due to decreased metabolism of chloropyramine in liver disease.
Patients with impaired renal function
The drug regimen and dose reduction may be required due to the fact that chloropyramine is mainly excreted by the kidneys.
Interaction
Monoamine oxidase inhibitors increase and prolong the anticholinergic effects of chloropyramine.
Particular caution should be exercised when using chloropyramine tablets simultaneously with barbiturates, hypnotics, anxiolytics and sedatives, tranquilizers, opioid analgesics, tricyclic antidepressants, atropine, muscarinergic parasympatholytics (chloropyramine and any of these drugs may increase the effects of each other).
Alcoholic beverages are prohibited during treatment (alcohol increases the CNS depressant effect of chloropyramine).
In combination with ototoxic drugs, chloropyramine may mask the early signs of ototoxicity.
Antihistamines inhibit skin reactions in response to allergic skin tests, thus, chloropyramine should be discontinued several days before the skin tests.
Special Instructions
The use of chloropyramine in the late evening hours may worsen symptoms of gastroesophageal reflux disease.
In combination with ototoxic drugs, chloropyramine may mask early signs of ototoxicity.
Hepatic and renal disease may require modification (reduction) of the drug dose, and therefore, the patient should inform the physician if he or she has hepatic and renal disease.
Because of its anticholinergic and sedative effect, chloropyramine should be prescribed with caution in elderly patients, patients with liver dysfunction, cardiovascular disease, closed-angle glaucoma, urinary retention and prostatic hyperplasia.
Chloropyramine may increase the effects of alcohol on the CNS, therefore, drinking alcoholic beverages while taking the drug is prohibited.
Long-term use of antihistamines may lead to disorders of the blood system and hematopoiesis (leukopenia, agranulocytosis, thrombocytopenia, hemolytic anemia). If during long-term use unexplained increase in body temperature, laryngitis, pale skin, jaundice, formation of mouth ulcers, appearance of bruises, unusual and prolonged bleeding it is necessary to conduct a clinical blood test with determination of the number of enzyme elements. If the test results indicate a change in blood count, the drug should be discontinued.
Each tablet contains 130 mg of lactose monohydrate. The drug is contraindicated in patients with lactase deficiency, lactose intolerance, glucose/galactose malabsorption.
Influence on ability to drive vehicles, mechanisms
The drug, especially in the initial period of treatment, may cause drowsiness, fatigue and dizziness. Therefore, during the initial period, the duration of which is determined individually, it is forbidden to drive vehicles or perform work associated with an increased risk of accidents. After that the degree of restriction to drive vehicles and work with mechanisms should be determined for each patient individually by a physician.

In young children, agitation predominates. Dry mouth, fixed dilation of the pupils, facial hyperemia, sinus tachycardia, urinary retention, and fever sometimes occur. In adults, fever and facial hyperemia may be absent; the period of agitation is followed by convulsions and post-convulsive depression with possible development of coma and cardiovascular and respiratory failure, which may result in the death of the patient within 2-18 hours.
Treatment: due to the anticholinergic effect of this drug, gastric emptying is delayed. Thus, inducing vomiting, gastric lavage and administration of activated charcoal are recommended within 12 hours after overdose. Monitoring of cardiovascular and respiratory system parameters, symptomatic therapy are recommended.
Specific antidote is unknown.
Pregnancy use
Pregnancy
There have been no adequately controlled clinical trials of antihistamines in pregnant women. However, cases of retrolental fibroplasia have been described in neonates whose mothers took antihistamines in the last months of pregnancy.
