Pharmacological properties

Piroxicam inhibits the activity of the enzyme cyclooxygenase 1 and 2, reduces the production of thromboxanes and prostaglandins (including PGE1, PGE2 alpha, PGE2). Piroxicam inhibits platelet aggregation and phagocytosis. When ingested, piroxicam is well absorbed from the gastrointestinal tract, the maximum concentration is reached after 3-5 hours. Within 7-12 days, the equilibrium concentration of piroxicam in the blood is established. With plasma proteins, the drug binds to 97–99%. In the liver, piroxicam undergoes metabolism (conjugates and oxidizes) to form the main metabolites of N-methyl-benzosulfonamide, 5-hydroxypyroxicam and others, which are pharmacologically inactive.

The half-life of piroxicam is approximately 50 hours, with liver diseases it can increase. It is excreted by piroxicam by the kidneys and intestines (in the urine the amount of the drug is 2 times greater than in feces), mainly in the form of glucuronides (5% is excreted unchanged).
