  • MetabollsmIndomethacin exists in the plasma as the parent drug and its desmethyl, desbenzoyl, and desmethyl-desbenzoyl metabolites produced by CYP 1A2, 2C11, 2E1, 2C9 and 2C19 all in the unconjugated form. About 60 percent of an oral dosage is recovered in urine as drug and metabolites (26 percent as indomethacin and its glucuronide formed by UGT 1A3, 1A9, 1A1 and 2B7), and 33 percent is recovered in feces (1.5 percent as indomethacin).
