Glucaric acid as an indicator of use of enzyme‐inducing drugs [PDF]

Clinical Pharmacology & Therapeutics, 1974
The usefulness of urinary glucaric acid determinations to measure enzyme induction by drugs was investigated by correlating its excretion rate with the daily drug regimen of 100 hospitalized patients. The urinary excretion of glucaric acid was higher in patients than in normal controls.
