 |  | Tiaprofenic acid Usage And Synthesis |  
 | Chemical Properties | White or almost white, crystalline powder. |  | Originator | Surgam,Roussel,France,1975 |  | Uses | Antiinflammatory;Cyclooxygenase inhibitor |  | Definition | ChEBI: An aromatic ketone that is thiophene substituted at C-2 by benzoyl and at C-4 by a 1-carboxyethyl group. |  | Manufacturing Process | A mixture of 10.3 g of thiophene-2α-methylacetic acid [prepared by process of
Bercot-Vatteroni, et al., Bull. Soc. Chim. (1961) pp. 1820-21], 11.10 g of
benzoyl chloride and a suspension of 23.73 g of aluminum chloride in 110 cc
of chloroform was allowed to stand for 15 minutes and was then poured into a
mixture of ice and hydrochloric acid. The chloroform phase was extracted with
a 10% aqueous potassium carbonate solution and the aqueous alkaline phase
was acidified with N hydrochloric acid and was then extracted with ether. The
ether was evaporated off and the residue was crystallized from carbon
tetrachloride to obtain a 54% yield of 5-benzoyl-thiophene-2α-methylacetic
acid melting at 83°C to 85°C. The product occurred in the form of colorless
crystals soluble in dilute alkaline solutions, alcohol and ether and insoluble in
water. |  | Therapeutic Function | Antiinflammatory |  | 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 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 | Sparingly metabolised in the liver to two inactive metabolites. Excretion of tiaprofenic acid and its metabolites are mainly in the urine in the form of acyl glucuronides; some is excreted in the bile. |
