 |  | Tenoxicam Usage And Synthesis |  
 | Description | Tenoxicam is a non-steroidal antiinflammatory agent with a profile similar to related
piroxicam and now withdrawn isoxicam (55). It is useful in the treatment of rheumatoid
arthritis, osteoarthritis and related disorders. |  | Chemical Properties | Yellow Crystalline Powder |  | Originator | Hoffmann-La Roche (Switzerland) |  | Uses | Tenoxicam has been used:     as a non-steroidal anti-inflammatory agent (NSAID) to study its effects on root gravitropism in Arabidopsis thaliana     as a standard in microanalysis of NSAIDs by spectrophotometry     to test its effect on surface potential andmembrane fluidity modification in phosphoglyceride monolayers |  | Definition | ChEBI: Tenoxicam is a thienothiazine-derived monocarboxylic acid amide obtained by formal condensation of the carboxy group of 4-hydroxy-2-methylthieno[2,3-e][1,2]thiazine-3-carboxylic acid 1,1-dioxide with the amino group of 2-aminopyridine. Used for the treatment of pain and inflammation in osteoarthritis and rheumatoid arthritis. It is also indicated for short term treatment of acute musculoskeletal disorders including strains, sprains and other soft-tissue injuries. It has a role as a non-steroidal anti-inflammatory drug, a non-narcotic analgesic, an antipyretic and an EC 1.14.99.1 (prostaglandin-endoperoxide synthase) inhibitor. It is a heteroaryl hydroxy compound, a monocarboxylic acid amide, a member of pyridines and a thienothiazine. |  | Brand name | Tilcotil |  | Biochem/physiol Actions | Tenoxicam (TX) possesses antipyretic?and analgesic effects. It elicits radical scavenging activity and has the potential to treat enkylosing spondylitis, extra-articular diseases, acute gout, and rheumatic diseases. It is also effective in treating primary dysmenorrhea, postpartum uterine contraction pain, and post-operation backaches. TX is capable of inhibiting prostaglandin synthesis. |  | Clinical Use | NSAID and analgesic |  | Drug interactions | Potentially hazardous interactions with other drugs 
 ACE inhibitors and angiotensin-II antagonists: 
antagonism of hypotensive effect; increased risk of 
nephrotoxicity and hyperkalaemia. 
 Analgesics: avoid concomitant use of 2 or more 
NSAIDs, including aspirin (increased side effects); 
avoid with ketorolac (increased risk of side effects 
and haemorrhage). 
 Antibacterials: possibly increased risk of convulsions 
with quinolones. 
 Anticoagulants: effects of coumarins and 
phenindione enhanced; possibly increased risk of 
bleeding with heparins, dabigatran and edoxaban - 
avoid long term use with edoxaban. 
 Antidepressants: increased risk of bleeding with 
SSRIs and venlaflaxine. 
 Antidiabetic agents: effects of sulphonylureas 
enhanced. 
 Antiepileptics: possibly increased phenytoin 
concentration. 
 Antivirals: increased risk of haematological toxicity 
with zidovudine; concentration possibly increased by 
ritonavir. 
 Ciclosporin: may potentiate nephrotoxicity. 
 Cytotoxics: reduced excretion of methotrexate; 
increased risk of bleeding with erlotinib. 
 Diuretics: increased risk of nephrotoxicity; 
antagonism of diuretic effect; hyperkalaemia with 
potassium-sparing diuretics. 
 Lithium: excretion decreased. 
 Pentoxifylline: increased risk of bleeding. 
 Tacrolimus: increased risk of nephrotoxicity. |  | Metabolism | Metabolised in the liver via cytochrome P450 2C9 to 
several pharmacologically inactive metabolites (mainly 
5'-hydroxy-tenoxicam). 
Metabolites are excreted mainly in the urine; there is 
some biliary excretion of glucuronide conjugates of the 
metabolites. |
