Biochem/physiol Actions

Tienilic Acid (Ticrynafen) is a P450 inhibitor, a specific suicide substrate for CYP2C9 and CYP2C10. It was once used as a loop diuretic drug with uric acid-lowering (uricosuric) actvity, but was removed from market because of hepatotoxicity.

Drug-induced autoimmune hepatitis is among the most severe hepatic idiosyncratic adverse drug reactions. Considered multifactorial, the disease combines immunological and metabolic aspects, the latter being to date much better known. As for many other model drugs, studies on tienilic acid
