Pharmacology
Indication For the treatment of rheumatoid arthritis, osteoarthritis, backache, and pain.
Pharmacodynamics Tenoxicam, an antiinflammatory agent with analgesic and antipyretic properties, is used to treat osteoarthritis and control acute pain.
Mechanism of action The antiinflammatory effects of tenoxicam may result from the inhibition of the enzyme cycooxygenase and the subsequent peripheral inhibition of prostaglandin synthesis. As prostaglandins sensitize pain receptors, their inhibition accounts for the peripheral analgesic effects of tenoxicam. Antipyresis may occur by central action on the hypothalamus, resulting in peripheral dilation, increased cutaneous blood flow, and subsequent heat loss.
Absorption Oral absorption of tenoxicam is rapid and complete (absolute bioavailability 100%).
Volume of distribution Not Available
Protein binding 99%
Metabolism

Tenoxicam is metabolized in the liver to several pharmacologically inactive metabolites (mainly 5'-hydroxy-tenoxicam).

Enzymes

1. Cytochrome P450 2C9

Actions: substrate

Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. This enzyme contributes to the wide pharmacokinetics variability of the metabolism of drugs such as S- warfarin, diclofenac, phenytoin, tolbutamide and losartan
