4 Drug and Medication Information
4.1 Drug Indication

For the treatment of rheumatoid arthritis, osteoarthritis, backache, and pain.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Tenoxicam, an antiinflammatory agent with analgesic and antipyretic properties, is used to treat osteoarthritis and control acute pain.


5.2 MeSH Pharmacological Classification

Anti-Inflammatory Agents, Non-Steroidal

Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. (See all compounds classified as Anti-Inflammatory Agents, Non-Steroidal.)


Cyclooxygenase Inhibitors

Compounds or agents that combine with cyclooxygenase (PROSTAGLANDIN-ENDOPEROXIDE SYNTHASES) and thereby prevent its substrate-enzyme combination with arachidonic acid and the formation of eicosanoids, prostaglandins, and thromboxanes. (See all compounds classified as Cyclooxygenase Inhibitors.)

5.4 Absorption, Distribution and Excretion

Absorption

Oral absorption of tenoxicam is rapid and complete (absolute bioavailability 100%).


5.5 Metabolism/Metabolites

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


Tenoxicam has known human metabolites that include 5'-Hydroxytenoxicam.

S73 | METXBIODB | Metabolite Reaction Database from BioTransformer | DOI:10.5281/zenodo.4056560


5.6 Biological Half-Life

72 hours (range 59 to 74 hours)


5.7 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.
