pharmachologic effect

Pharmacological action - antipyretic, analgesic.


Paracetamol (para-aminophenol derivative) has analgesic, antipyretic and mild anti-inflammatory effects. The exact mechanism of analgesic and antipyretic effects of paracetamol is not established. Apparently, it includes the central and peripheral components. The drug blocks COX-1 and -2 predominantly in the central nervous system, affecting the centers of pain and thermoregulation. In inflamed tissues, cellular peroxidases neutralize the effect of paracetamol on COX, which explains the almost complete lack of anti-inflammatory effect. The drug does not adversely affect water-salt metabolism (sodium and water retention) and gastrointestinal mucosa due to the absence of influence on the synthesis of PG in peripheral tissues.


Absorption. When ingested paracetamol is absorbed quickly and completely. Cmax paracetamol in plasma is achieved 10 to 60 minutes after administration.

Distribution. Paracetamol is rapidly distributed in all tissues. Concentration in blood, saliva and plasma is the same. Binding to plasma proteins is negligible.

Metabolism. Paracetamol is mainly metabolized in the liver. There are 2 main ways of metabolism with the formation of glucuronides and sulfates. The latter basically plays a role if the accepted dose of paracetamol exceeds the therapeutic dose. An insignificant amount of paracetamol is metabolized by cytochrome P450 isoenzymes to form an intermediate of N-acetylbenzoquinonimine, which under normal conditions undergoes rapid detoxification with glutathione and is excreted in the urine after binding to cysteine and mercaptopuric acid. However, with massive intoxication, the content of this toxic metabolite increases.

Excretion. It is carried out mainly with urine. 90% of the accepted dose of paracetamol is excreted by the kidneys within 24 hours, mainly in the form of glucuronide (60 to 80%) and sulfate (20 to 30%). Less than 5% is displayed unchanged. T1 / 2 is about 2 hours.

Pharmacokinetics in specific patient groups

Impaired renal function. With severe impairment of kidney function (Cl creatinine <30 ml / min) excretion of paracetamol and its metabolites is delayed.


Moderate or mild pain syndrome (headache, toothache, migraine pain, neuralgia, muscle pain, back pain, pain in injuries and burns, sore throat, painful menstruation);

elevated body temperature for colds and other infectious and inflammatory diseases.


hypersensitivity to paracetamol or any other component of the drug;

severe hepatic impairment or decompensated liver disease in the acute stage;

deficiency of sugar / isomaltase, intolerance to fructose, glucose-galactose malabsorption;

children under 12 years.

With caution: severe renal failure (Cl creatinine <30 mL / min); liver failure; chronic alcoholism; nutritional deficiency; anorexia; bulimia; cachexia; hypovolemia; dehydration; deficiency of glucose-6-phosphate dehydrogenase, congenital hyperbilirubinemia (Gilbert syndrome, Dubin-Johnson and Rotor syndrome), viral hepatitis, elderly age.

pregnancy and lactation

The drug should be used during pregnancy only if the expected benefit for the mother exceeds the possible risk to the fetus, strictly observing the dosing regimen and the timing of treatment. Clinical experience with paracetamol during pregnancy and during breastfeeding is limited. However, according to epidemiological data on the use of paracetamol in therapeutic doses, undesirable effects on the course of pregnancy or the health of the fetus and the newborn have not been revealed.

Reproductive toxicity studies in animals showed no teratogenic, embryotoxic or fetotoxic potential. After ingestion of paracetamol, it penetrates into breast milk in small amounts. In some cases, the appearance of a rash was noted in children whose mothers used paracetamol during the period of breastfeeding. Paracetamol may be used during the period of breastfeeding in therapeutic doses.

Side effects

When using the drug, the following side effects were noted (frequency not established).

Allergic reactions: hypersensitivity reactions, skin itching, rashes on the skin and mucous membranes (erythema or urticaria), Quincke's edema, erythema multiforme exudative (including Stephens-Johnson syndrome), toxic epidermal necrolysis (Lyell's syndrome), anaphylactic shock, acute generalized exanthematous pustulosis.

From the central and peripheral nervous system (when taking high doses): dizziness, psychomotor agitation and disorientation in space and time.

On the part of the digestive system: nausea, diarrhea, epigastric pain, increased activity of hepatic enzymes, usually without the development of jaundice, hepatonecrosis (dose-dependent effect).

From the endocrine system: hypoglycemia, up to hypoglycemic coma.

From the hematopoiesis: anemia (cyanosis), sulfogemaglobinemia, methemoglobinemia (dyspnea, heart pain), hemolytic anemia (especially in patients with deficiency of glucose-6-phosphate dehydrogenase), thrombocytopenia, neutropenia, and leukopenia.

Other: decrease in blood pressure (as a symptom of anaphylaxis), changes in PV and MHO.


Phenytoin reduces the effectiveness of paracetamol and increases the risk of hepatotoxicity. Patients taking phenytoin should avoid frequent use of paracetamol, especially in high doses.

Probenecid almost 2 times reduces the clearance of paracetamol, inhibiting the process of its conjugation with glucuronic acid. With a simultaneous appointment, consideration should be given to reducing the dose of paracetamol.

Caution should be exercised while using paracetamol and inducers of microsomal liver enzymes (eg ethanol, barbiturates, isoniazid, rifampicin, carbamazepine, anticoagulants, zidovudine, amoxicillin + clavulanic acid, phenylbutazone, tricyclic antidepressants).

The prolonged simultaneous use of barbiturates reduces the effectiveness of paracetamol.

Salicylamide can increase T1 / 2 paracetamol.

MHO should be monitored during and after the concurrent use of paracetamol (especially in high doses and / or for a long time) and coumarins (eg warfarin) because paracetamol when taken in a dose of 4 g / day for at least 4 days can enhance the effect of indirect anticoagulants and increase the risk of bleeding. If necessary, correct the dose of anticoagulants.

Dosing and Administration

Inside, previously dissolved in a glass of water (200 ml). Do not chew or swallow tablets.

Usually apply 1-2 tablets 2-3 times a day at intervals of not less than 4 hours.

The maximum single dose is 2 tablets. (1 g), the maximum daily - 8 tablets. (4 g), which corresponds to a maximum single dose of 10-15 mg / kg, for a maximum daily dose of 75 mg / kg.

As a rule, there is no need to exceed the recommended daily dose of paracetamol, equal to 3 g. The daily dose can be increased to a maximum (4 g) only in case of severe pain. If the renal function is impaired, the time interval between doses should be at least 8 hours with Cl creatinine <10 ml / min, at least 6 hours - with Cl creatinine 10-50 ml / min.

In patients with chronic or compensated active liver disease, especially accompanied by liver failure, in patients with chronic alcoholism, chronic malnutrition (insufficient stock of glutathione in the liver), Gilbert's syndrome (hereditary hyperbilirubinemia), dehydration or body weight less than 50 kg, the dose of the drug should be decreased or increased the interval between doses. The daily dose should not exceed 2 g, i.ň. 4 tab.

The drug should be used with caution in children and patients with a body weight of less than 50 kg to avoid the risk of exceeding the recommended dose.

Dosage regimen in children older than 12 years and body weight over 43 kg is the same as in adults, with the interval should preferably be 6 hours (strictly no less than 4 hours).

Duration of admission without consulting a doctor is no more than 5 days when prescribed as an anesthetic and 3 days - as an antipyretic.


Symptoms: intoxication is possible, especially in children, patients with liver diseases caused by chronic alcoholism, in patients with eating disorders, as well as in patients taking enzyme inducers, at which fulminant hepatitis, hepatic insufficiency, cholestatic hepatitis, cytolytic hepatitis, in mentioned cases - sometimes with a fatal outcome.

The clinical picture of acute overdose develops within 24 hours after taking paracetamol - gastrointestinal disorders (nausea, vomiting, decreased appetite, abdominal discomfort and / or abdominal pain), pallor of the skin, sweating, malaise. When single-step introduction of adults and more than 7.5 g or children of more than 140 mg / kg cytolysis of hepatocytes occurs with complete and irreversible necrosis of liver development of hepatic insufficiency, metabolic acidosis and encephalopathy, which may lead to coma and death. After 12-48 hours after the introduction of paracetamol, an increase in the activity of hepatic transaminases, LDH, bilirubin concentration and a decrease in the prothrombin concentration was noted. Clinical symptoms of liver damage are manifested 1-2 days after drug overdose and reach a maximum on the 3-4th day.

Treatment: immediate hospitalization; determination of the quantitative content of paracetamol in the blood plasma before the start of treatment at the earliest possible time after an overdose; gastric lavage; introduction of donors of SH-groups and precursors of the synthesis of glutathione - methionine and acetylcysteine - within 8 hours after an overdose. The need for additional therapeutic measures (further introduction of methionine, iv injection of acetylcysteine) is determined depending on the concentration of paracetamol in the blood, as well as on the time elapsed after its administration; symptomatic treatment; hepatic tests should be performed at the beginning of treatment and then every 24 hours. In most cases, liver transaminase activity normalizes within 1-2 weeks. In very serious cases, liver transplantation may be required.

special instructions

In order to avoid an overdose, the paracetamol content in other drugs taken by the patient at the same time as Efferalgan« should be considered. The use of paracetamol in doses exceeding the recommended levels can cause severe liver damage. With continued febrile syndrome in the presence of paracetamol (more than 3 days) and pain syndrome (more than 5 days), a doctor's consultation is required.

The use of Efferalgan« may distort laboratory performance in quantifying glucose and uric acid in the plasma. In order to avoid toxic damage to the liver, paracetamol should not be combined with the intake of alcoholic beverages, as well as to people who are prone to chronic alcohol consumption. The risk of liver damage increases in patients with alcoholic hepatosis. When the drug is used for a long time, it is necessary to monitor the pattern of peripheral blood and the functional state of the liver.

Paracetamol can cause severe skin reactions, such as Stephens-Johnson syndrome, toxic epidermal necrolysis, acute generalized exanthematous pustulosis, which can be lethal.

At the first manifestation of a rash or other hypersensitivity reactions, the drug should be discontinued. Also, the use of paracetamol should be discontinued if a patient has acute viral hepatitis. Efferalgan« contains 412.4 mg sodium per tablet, which should be taken into account by patients on a strict low-salt diet.

Since the drug contains sorbitol, it should not be used in case of sugarase / isomaltase deficiency, fructose intolerance, glucose-galactose malabsorption.

Influence on the ability to drive vehicles and work with mechanisms. Not studied. If the patient experiences dizziness, psychomotor agitation and disorientation in space and time, he is not recommended to drive and other mechanisms during treatment with the drug.
