Paracetamol-Altfarm suppositories rectal 500mg, 10pcs

Composition

Active ingredient:

paracetamol 500 mg;

Auxiliary substances:  

solid fat base before receiving a suppository weighing 1.25 g

Pharmacological action

Paracetamol is an analgesic and antipyretic agent. Blocks the synthesis of prostaglandins in the central nervous system by inhibiting cyclooxygenase 1 and cyclooxygenase 2, affecting the centers of pain and thermoregulation. It has no anti-inflammatory effect.

The lack of influence on prostaglandin synthesis in peripheral tissues means that it has no negative effect on water-salt metabolism (sodium and water retention) and the gastrointestinal mucosa.

Pharmacokinetics

Paracetamol is rapidly and almost completely absorbed from the gastrointestinal tract. It binds to plasma proteins by 15%. Paracetamol penetrates the blood-brain barrier.

Less than 1% of the dose of paracetamol taken by a nursing mother passes into breast milk. A therapeutically effective plasma concentration of paracetamol is achieved when it is administered at a dose of 10-15 mg / kg of body weight.

The elimination half-life is 1-4 hours. Paracetamol is metabolized in the liver and excreted in the urine, mainly in the form of glucuronides and sulfonated conjugates, less than 5% is excreted unchanged in the urine.

Indications

It is used to quickly relieve headaches, including migraine pain, toothache, neuralgia, muscle and rheumatic pain, as well as for algodismenorrhea, pain from injuries, burns; to reduce fever in colds and flu.

Contraindications

• hypersensitivity to paracetamol or any other ingredient of the drug;
• severe liver or kidney function disorders;
• children (up to 3 years)

With caution:  use with caution in patients with benign hyperbilirubinemia( including Gilbert’s syndrome), viral hepatitis, alcoholic liver damage, glucose-6-phosphate dehydrogenase deficiency, alcoholism, pregnancy, lactation, and the elderly. The drug should not be taken simultaneously with other paracetamol-containing drugs.

Side effects

At the recommended doses, the drug is usually well tolerated. Paracetamol rarely causes side effects. Sometimes allergic reactions (skin rash, pruritus, urticaria, Quincke’s edema), erythema multiforme (including Stevens-Johnson syndrome), toxic epidermal necrolysis (Lyell’s syndrome), dizziness, nausea, epigastric pain; anemia, thrombocytopenia, agranulocytosis; insomnia may occur. Long-term use in large doses increases the likelihood of impaired liver and kidney function, as well as the hematopoietic system.

From the digestive system:  nausea, epigastric pain, increased activity of liver enzymes, hepatonecrosis. Endocrine system disorders: hypoglycemia. If you experience unusual symptoms, you should consult a doctor.

Interaction

The drug, when taken for a long time, increases the effect of indirect anticoagulants (warfarin and other coumarins), which increases the risk of bleeding. Inducers of microsomal oxidation enzymes in the liver (barbiturates, diphenine, carbamazepine, rifampicin, zidovudine, phenytoin, ethanol, flumecinol, phenylbutazone, and tricyclic antidepressants) increase the risk of hepatotoxic effects in overdoses.

Long-term use of barbiturates reduces the effectiveness of paracetamol.

Ethanol contributes to the development of acute pancreatitis.

Microsomal oxidation inhibitors (cimetidine) reduce the risk of hepatotoxic effects. Combined use with other nonsteroidal anti-inflammatory drugs increases the nephrotoxic effect.

Concomitant long-term use of high-dose paracetamol and salicylates increases the risk of kidney and bladder cancer. Diflunisal increases the plasma concentration of paracetamol by 50% – the risk of developing hepatotoxicity.

Myelotoxic drugs increase the manifestations of hematotoxicity of the drug. Metoclopramide and domperidone increase, and cholestyramine reduces the rate of absorption of paracetamol. The drug may reduce the activity of uricosuric drugs.

How to take, course of use and dosage

For children aged from 1 month to 3 years, rectal suppositories are used, a single dose of paracetamol is 15 mg per 1 kg of body weight, daily-60 mg per 1 kg of body weight of the child. The frequency of use is 3-4 times a day. For adults and adolescents with a body weight above 60 kg, a single dose is 0.35-0.5 g, the maximum single dose is 1.5 g 3-4 times a day. The daily dose is 3-4 g. For children from 6 to 12 years, the maximum daily dose is 2 g in 4 doses. For children from 3 to 6 years, the maximum daily dose is 1-2 g of paracetamol, at the rate of 60 mg per 1 kg of body weight of the child in 3-4 doses.

Overdose

Signs of paracetamol overdose include nausea, vomiting, stomach pain, pallor of the skin, and anorexia. After a day or two, signs of liver damage are detected. In severe cases, liver failure and a comatose state develop. A specific antidote for paracetamol poisoning is N-acetylcysteine.

Symptoms:  pallor of the skin, anorexia, nausea, vomiting; hepatonecrosis (the severity of necrosis directly depends on the degree of overdose). If an overdose is suspected, seek immediate medical attention. The toxic effect of the drug in adults is possible after taking more than 10-15 g of paracetamol: an increase in the activity of “liver” transaminases, an increase in prothrombin time (12-48 hours after use); a detailed clinical picture of liver damage is manifested in 1-6 days. Rarely, liver dysfunction develops rapidly and can be complicated by renal failure (tubular necrosis).

Treatment:  the victim should be given gastric lavage during the first 4 hours of poisoning, take adsorbents (activated charcoal) and consult a doctor, administer SH-group donors and glutathione – methionine synthesis precursors 8-9 hours after overdose and N-acetylcysteine – 12 hours after overdose. The need for additional therapeutic measures (further use of methionine, intravenous use of N-acetylcysteine) is determined depending on the concentration of paracetamol in the blood, as well as on the time elapsed after taking it.

Special instructions

Please consult your doctor before taking this medicine if: :

• You have severe liver or kidney disease.
• You are taking anti-nausea and vomiting medications (metoclopramide, domperidone), as well as cholesterol-lowering medications (cholestyramine).
• You are taking anticoagulants and need painkillers every day for an extended period of time. Paracetamol in this case can be taken occasionally;

IN ORDER TO AVOID TOXIC LIVER DAMAGE, PARACETAMOL SHOULD NOT BE COMBINED WITH THE INTAKE OF ALCOHOLIC BEVERAGES, AS WELL AS TAKEN BY PEOPLE WHO ARE PRONE TO CHRONIC ALCOHOL CONSUMPTION.

During long-term treatment, it is necessary to monitor the picture of peripheral blood and the functional state of the liver.
