The composition of Panadol

The tablet in a special film membrane contains 500 mg of paracetamol. Additional components: povidone, potassium sorbate, corn starch, triacetin, pregelatinized starch, hypromellose, stearic acid, talc.
Composition of the soluble tablet: 500 mg of active substance and additional components: dimethicone, sodium lauryl sulfate, povidone, sodium carbonate, citric acid, sodium hydrogen carbonate, sodium saccharinate, sorbitol.

Form of issue

Panadol is available in tablet form: soluble tablets Panadol and tablets in a film membrane.
Soluble tablets have a white color, a flat shape, a rough surface, a chamfered edge and a risk on one side.
The film-coated tablets have a capsular shape, flat edges, white color, a risk on one side, and a special "Panadol" embossing on the other side.

pharmachologic effect

Antipyretic analgesic. The active ingredient has antipyretic, analgesic effects. The principle of action is based on the blocking of COX-1, 2 mainly in the central nervous system. The active component acts on the centers of thermoregulation and pain.
The anti-inflammatory effect in paracetamol is practically not expressed. The active ingredient does not irritate the mucous membranes of the digestive tract (intestines, stomach). Panadol is not able to influence the process of synthesizing prostaglandins in peripherally located tissues, so the drug does not affect water-salt metabolism.

Pharmacodynamics and pharmacokinetics

The medication is quickly absorbed from the lumen of the digestive tract through passive transport. The active component is absorbed mainly from the small intestine. The maximum concentration of paracetamol after a single intake of 500 mg is recorded after 10-60 minutes (C (max) = 6 μg / ml). After 6 hours the index gradually reaches the level of 11-12 μg / ml.
For the active substance is characterized by a uniform distribution in the liquid media and tissues of the body, without getting into the cerebrospinal fluid and adipose tissue.
The binding of plasma proteins does not exceed 10%, slightly increasing in overdose. Glucuronide and sulfate metabolites are not able to bind to plasma proteins even at relatively high dosages. Panadol is metabolized predominantly in the hepatic system by conjugation with sulfate and glucuronide, as well as by oxidation involving cytochrome P450 and mixed hepatic oxidases.
N-acetyl-p-benzoquinonimine (hydroxylated metabolite with a negative effect), formed in small amounts in the renal and hepatic systems as a result of the interaction of mixed forms of oxidases, is detoxified by binding to glutathione. When an overdose occurs, the accumulation of N-acetyl-p-benzoquinonimine, which can cause tissue damage. A significant part of paracetamol binds to glucuronic acid, insignificant - with sulfuric acid. The listed conjugated metabolites have no biological effect and do not have activity. The metabolism with the formation of sulfate metabolites is characteristic for newborn and premature babies.
The half-life period is 1-3 hours. With cirrhotic lesions of the hepatic system, T1 \ 2 significantly increases. Kidney clearance reaches 5%. Through the renal system, the medication is excreted in the urine in the form of sulfate and glucuronide conjugates. In an unchanged form, less than 5% of paracetamol is excreted.

Instructions for use Panadol (Method and dosage)

Conventional tablets Panadol, instructions for use
Adults appoint 500-1000 mg to 4 times a day if necessary. The recommended time interval between receptions is 4 hours. A day can take no more than 8 tablets. Do not use Panadol for a long time as an analgesic (maximum 5 days) and antipyretic (no more than 3 days) funds. The decision to increase the daily dosage or duration of therapy is taken by the treating doctor.
Effervescent tablets Panadol, instructions for use
Tablets before use dissolve in a glass with water. A day can take no more than 4 tablets. Soluble Panadol is prescribed primarily with difficulty swallowing tablets and in pediatric practice.

Overdose

The manufacturer recommends taking the medication only in the dosages specified in the instructions. When taking high doses, you need to immediately seek medical help, even in the absence of negative symptoms, because possibly delayed lesion of the hepatic system. In adult patients, the first signs of liver damage are observed when taking more than 10 grams of medication. The intake of more than 5 grams has a toxic effect in a certain category of citizens who have risk factors:
    consumption of alcohol-containing beverages in large quantities and with high frequency;
    reception of Phenytoin, Phenobarbital, carbamazepine, rifampicin, primidon, preparations of St. John's wort and other medications that stimulate the production of hepatic enzymes;
    deficiency of glutathione (for HIV infection, cystic fibrosis, malnutrition, starvation and exhaustion).
Signs of poisoning:
    increased sweating;
    nausea;
    epigastric pain;
    pallor of the skin;
    vomiting.
In severe poisoning, acute renal failure, arrhythmia, encephalopathy, coma, tubular necrosis, pancreatitis can develop.
Treatment includes gastric lavage, the use of enterosorbent medications (Polyphepan, Activated Carbon), the introduction of the precursors of the synthesis of glutathione-methionine and donators of SH groups. With severe lesions of the hepatic system, treatment is conducted under the guidance of specialists from the toxicological center.

Interaction

The risk of hepatotoxic damage increases with simultaneous treatment with inductors of microsomal hepatic enzymes and drugs showing hepatotoxic effects. A moderately pronounced or insignificant increase in the prothrombin time is recorded.
Absorption of paracetamol decreases with the appointment of anticholinergic medications. The severity of the analgesic effect is reduced, and excretion is accelerated by oral contraceptives. Paracetamol inhibits the activity of uricosuric drugs. The indicator of bioavailability of Panadol decreases with the reception of activated carbon. A decrease in the excretion of Diazepam is registered.
In relation to Zidovudine, there is an increase in the myelodepressive effect. In medical practice 1 case of severe toxic damage of the hepatic system was registered. Toxic effects increase with isoniazid. There is an acceleration of metabolism (oxidation, glucuronization) of paracetamol and a decrease in its effectiveness with the simultaneous use of the following medicines:
    Phenytoin;
    Carbamazepine;
    Primidone;
    Phenobarbital (increased hepatotoxicity).
Kolestyramin slows the absorption of Paracetamol (if the time interval between receptions is not observed at 1 hour). Panadol accelerates the excretion of lamotrigine. Metoclopramide increases the concentration of paracetamol in the blood, increasing its absorption. Probenecid reduces the clearance of Panadol. The reverse effect is observed with respect to Sulfinpyrazone and Rifampicin. Ethinyl estradiol enhances the absorption of medication from the intestinal lumen.
