Mexold drug's main ingredient is acetaminophen (paracetamol) 500mg, is prepared in many different forms of capsules, tablets, powder or soluble granules.

Conditions including headache, muscle pain, arthritis, backache, toothache, sore throat, cold, flu, and fever are common conditions where acetaminophen is used.
Acetaminophen is usually taken orally, but can also be given intravenously.
Orally, Paracetamol is absorbed directly from the gastrointestinal tract very quickly after oral administration. Paracetamol is rapidly and evenly distributed in many body tissues. About 25% of Paracetamol in the blood is bound to plasma proteins. The half-life is about 2 hours. The liver metabolizes the drug and is excreted in the urine, mostly as conjugates with glucuronic acid. Pharmacodynamics Paracetamol is the active metabolite of phenacetin. Paracetamol has an effective analgesic and antipyretic effect that can replace aspirin. However, it is not effective in treating inflammation. Drugs acting on the hypothalamus cause hypothermia, increased heat loss due to vasodilation and increased peripheral blood flow.
Paracetamol with therapeutic doses has little impact on cardiovascular and respiratory systems, does not change acid-base balance, does not cause irritation, scratches or stomach bleeding like salicylate because paracetamol does not affect systemic cyclooxygenase but Only affects cyclooxygenase/prostaglandin of the central nervous system. Pharmacokinetics Absorption: Paracetamol is rapidly and almost completely absorbed from the gastrointestinal tract. Peak plasma concentrations are reached within 30-60 minutes after oral administration of a therapeutic dose.
Distribution: Paracetamol is rapidly and evenly distributed in most body tissues. Approximately 26% of paracetamol in the blood is bound to plasma proteins.
Metabolism: Paracetamol is n - hydroxylated by cytochrome P450 to form n - acetyl - benzoquinonimine, a highly reactive intermediate. This metabolite reacts with the sulfhydryl (thiol) groups in glutathione and is inactivated. However, when high doses of paracetamol are taken, this metabolite is formed in sufficient quantities to deplete hepatic glutathione, in which condition its reaction with the sulfhydryl group of liver proteins is increased, which can lead to necrosis. liver death.
