Pharmacotherapeutic group
Analgesics and antipyretics. ATX code N02B E01.

Pharmacodynamics
It has analgesic, antipyretic and mild anti-inflammatory effects. The mechanism of action is due to the inhibition of the synthesis of prostaglandins and the predominant effect on the center of thermoregulation in the hypothalamus.

Pharmacokinetics
Absorption of paracetamol with rectal administration is slower than with oral administration, but it is more complete. The maximum concentration in blood plasma is reached within 2-3 hours after administration.

Paracetamol is rapidly distributed in all tissues. Concentrations in blood, saliva and plasma are comparable to each other. Plasma protein binding is weak.

Paracetamol is metabolized in the liver to form inactive compounds with glucuronic acid and sulfates.

The minimal metabolic pathway catalyzed by cytochrome P450 leads to the formation of an intermediate reagent (N-acetylbenzoquinone imine), which, under normal use, is rapidly detoxified by reduced glutathione and excreted in the urine after conjugation with cysteine ​​and mercaptopuric acid. However, with massive poisoning, the amount of this toxic metabolite increases.

It is excreted mainly in the urine. 90% of the taken dose of paracetamol is excreted by the kidneys within 24 hours, mainly in the form of conjugates with glucuronic acid (60 to 80%) and sulfate conjugates (20 to 30%).

Less than 5% of the substance is excreted unchanged.

The half-life is 4 to 5 hours.

In severe renal failure (creatinine clearance below 10 ml / min), the excretion of paracetamol and its metabolites slows down.

Indications
Symptomatic treatment of diseases accompanied by mild to moderate pain and / or fever.

Contraindications
Hypersensitivity to paracetamol or other components of the drug.
