Description of the drug approved by the manufacturer for the printed edition of 2017.


Combined drug, the effect of which is due to its constituent components.
It has antipyretic, analgesic, vasoconstrictive action, eliminates the symptoms of "colds".Narrows the vessels and eliminates the swelling of the mucous membrane of the nasal cavity and nasopharynx.
Paracetamol has antipyretic effect, blocking COX mainly in the central nervous system, affecting the centers of pain and thermoregulation.
Almost no anti-inflammatory effect. Paracetamol does not affect the synthesis of prostaglandins in peripheral tissues, thus not adversely affecting water-salt metabolism (sodium and water retention) and gastrointestinal mucosa.
Phenylephrine - alpha-adrenomimetic, causes vasoconstriction, eliminates edema and flushing of the mucous membrane of the nasal cavity, nasopharynx and paranasal sinuses, reduces exudative manifestations (runny nose).

Chlorphenamine - a blocker of histamine H 1 -receptors, suppresses the symptoms of allergic rhinitis: sneezing, runny nose, itching of the eyes, nose, irritation in the pharynx and larynx.
The duration of action is 6 hours.


Paracetamol is rapidly and almost completely absorbed from the digestive tract.
C max in plasma is achieved after 10-60 min after ingestion. Paracetamol is widely distributed in all tissues of the body. It penetrates the placental barrier and is secreted with breast milk. Binding to blood plasma proteins is insignificant at usual therapeutic concentrations, but increases with increasing concentrations. Paracetamol is metabolized in the liver mainly by glucuronization and sulfation. It is excreted by the kidneys mainly in the form of glucuronide and sulfate conjugates. T 1/2 is between 1 and 3 hours. In cases of severe impairment of kidney function (CC <30 ml / min) excretion of paracetamol and its metabolites is delayed.
Phenylephrine hydrochloride

Phenylephrine hydrochloride is absorbed from the digestive tract.
Metabolized MAO with "first passage" through the wall of the intestine and the liver, so when administered phenylephrine hydrochloride is characterized by limited bioavailability. C max in plasma are reached within 45 min-2 h. It is excreted by the kidneys almost completely in the form of sulfate conjugates. T 1/2 of the drug from the plasma is 2-3 hours.
Chlorphenamine maleate

Chlorphenamine is relatively slowly absorbed from the gastrointestinal tract, C max of chlorphenamine in the blood plasma is reached 2.5 to 6 hours after taking the drug.
The substance has a low bioavailability of 25-50%. The binding of chlorphenamine to plasma proteins is about 70%. It is widely distributed in the tissues of the body, including the central nervous system. Chlorphenamine undergoes significant metabolism in the "first pass". Children showed faster and full absorption, higher clearance and shorter T 1/2 . T 1/2 is from 2 to 43 hours, even with an average duration of 4-6 hours. Part of chlorphenamine in unchanged form with metabolites is excreted by the kidneys.

- symptomatic treatment of infectious and inflammatory diseases (acute respiratory viral infection, including influenza) accompanied by fever, chills, headache, runny nose, stuffy nose, sneezing, muscle aches.


Is taken internally.
It is recommended to swallow the whole tablet without chewing, washing with water.
Adults - 1 tablet every 4-6 hours, but not more than 6 tablets a day.

Children over 12 years - 1 tablet every 4-6 hours, but not more than 4 tablets per day.

The course of treatment is no more than 5 days.

Impact on the ability to drive vehicles and mechanisms

During treatment it is not recommended to drive vehicles or other mechanisms that require concentration of attention and high speed of psychomotor reactions.



Symptoms: due mainly to the presence of paracetamol.
In acute overdose, paracetamol may have a hepatotoxic effect and even cause liver necrosis. An overdose of paracetamol, including a general high dose level after a long period of therapy, can result in analgesic-induced nephropathy with irreversible hepatic insufficiency.Patients should be warned about the inadmissibility of simultaneous administration of other drugs containing paracetamol. There is a risk of poisoning, especially in elderly patients and young children, people with liver disease, chronic alcoholism, patients with chronic eating disorders and patients receiving inducers of microsomal enzymes.
An overdose of paracetamol can lead to hepatic insufficiency, encephalopathy, coma and death.
Symptoms of a paracetamol overdose in the first day include pallor, nausea, vomiting and anorexia. Pain in the abdomen can be the first sign of liver damage, and it can appear only after 24-48 hours, sometimes 4-6 days after taking the drug. Most often, signs of liver damage occur 72-96 hours after taking the drug. Possible disturbance of glucose metabolism and metabolic acidosis. Acute renal failure and acute necrosis of the renal tubules can develop even in the absence of severe liver damage. There were cases of cardiac arrhythmia and pancreatitis.
Treatment: treatment of paracetamol overdose should be started immediately.
During the first 48 hours after an overdose, it is advisable to use N-acetylcysteine ​​IV orally as an antidote for paracetamol, possibly gastric lavage and / or methionine administration. It is advisable to use activated carbon. Control of breathing and circulation is necessary. In case of seizures, diazepam can be used.

Symptoms: sympathomimetic action, which causes hemodynamic changes and cardiovascular collapse with respiratory depression, manifested in the form of, for example, drowsiness, followed by excitation (especially in children), visual impairment, skin rash, nausea, vomiting, persistent headaches, nervousness, dizziness, insomnia, hematopoiesis disorders (thrombocytopenia, agranulocytosis, leukopenia, pancytopenia), coma, convulsions, arterial hypertension and bradycardia.

Treatment: immediate gastric lavage, symptomatic and maintenance therapy.
The hypertensive effect can be quenched by intravenous administration of an alpha-blocker. In case of seizures, diazepam may be used.

Symptoms: drowsiness, respiratory arrest, convulsions, anticholinergic effects, dystonic reactions and cardiovascular collapse, including arrhythmia.
In children, the symptoms of overdose may include impaired coordination, agitation, tremors, behavioral changes, hallucinations, seizures and anticholinergic effects.
Treatment: gastric lavage in case of a massive overdose, or stimulation of vomiting.
After that, it is possible to use activated carbon and a laxative to slow the absorption. In the case of convulsions, iv diazepam or phenytoin should be administered. In severe cases, hemoperfusion can be performed.


With prolonged regular use of paracetamol, an increase in the anticoagulant effect of warfarin and other coumarins is possible, and the risk of bleeding increases.Periodic use of paracetamol has no significant effect.

Hepatotoxic substances can lead to the accumulation of paracetamol and an overdose.
The risk of hepatotoxicity of paracetamol is enhanced by the use of drugs that induce microsomal liver enzymes, such as barbiturates, antiepileptic drugs (eg, phenytoin, phenobarbital, carbamazepine) and drugs for the treatment of tuberculosis, such as rifampicin and isoniazid.
Metoclopramide increases the rate of absorption of paracetamol and increases its C max in blood plasma.
Similarly, domperidone may increase the rate of absorption of paracetamol.
Paracetamol can lead to an increase in T 1/2 chloramphenicol.

Paracetamol is able to reduce the bioavailability of lamotrigine, with the possible decrease in the effectiveness of lamotrigine due to the induction of its metabolism in the liver.

Absorption of paracetamol can be reduced with simultaneous application with colestyramine, but a decrease in absorption is slight, if kolestiramin take an hour later.

Regular use of paracetamol simultaneously with zidovudine can cause neutropenia and increase the risk of liver damage.

Probenecid affects the metabolism of paracetamol.
In patients who simultaneously use probenecid, the dose of paracetamol should be reduced.
Hepatotoxicity of paracetamol is enhanced by prolonged excessive use of ethanol (alcohol).

Paracetamol can affect the results of a uric acid test using the precipitating reagent phosphotungstate.


Contraindicated in patients receiving or receiving MAO inhibitors within the past 2 weeks.
Phenylephrine can potentiate the action of MAO inhibitors and induce an overactive crisis.
Simultaneous use of phenylephrine with other sympathomimetic drugs or tricyclic antidepressants (for example, amitriptyline) may lead to an increased risk of unwanted reactions from the cardiovascular system.

The use of phenylephrine can lead to a decrease in the effectiveness of beta-blockers and other antihypertensive agents (for example, debrisoquine, guanethidine, reserpine, methyldopa).
The risk of hypertension and other unwanted reactions from the cardiovascular system may increase.
The simultaneous use of phenylephrine with digoxin and cardiac glycosides may lead to an increased risk of heart rhythm or heart attack.

Simultaneous use of ergot alkaloids (ergotamine) may increase the risk of ergotism.


Chlorphenamine, like other antihistamines, can enhance the effect of opioid analgesics, anticonvulsants, antidepressants (tricyclics and MAO inhibitors), other antihistamines, antiemetics and antipsychotics, anxiolytics, hypnotics, ethanol (alcohol), and agents that exert a depressing effect on the central nervous system .

Since chlorphenamine has anticholinergic activity to some extent, the effects of anticholinergic drugs (eg, certain psychotropic drugs, atropine and drugs for the treatment of urinary incontinence) can be enhanced by the use of this drug.
This can lead to tachycardia, dryness of the oral mucosa, disorders of the digestive system (for example, colic), urinary retention and headache.
Chlorphenamine can inhibit the metabolism of phenytoin, and the development of phenytoin toxicity is possible.


The drug is approved for use as a means of OTC.


The drug should be stored out of reach of children at a temperature of no higher than 25 В° C.
Shelf life - 2 years.
