Hepatic. Meclofenamic acid is extensively metabolized to an active metabolite (Metabolite I; 3-hydroxymethyl metabolite of meclofenamic acid) and at least six other less well characterized minor metabolites. Only Metabolite I has been shown in vitro to inhibit cyclooxygenase activity with approximately one fifth the activity of meclofenamic acid.

Rapidly absorbed in man following single and multiple oral doses with peak plasma concentrations occurring in 0.5 to 2 hours. The concomitant administration of antacids (aluminum and magnesium hydroxides) does not interfere with absorption of meclofenamic acid. Unlike most NSAIDs, which when administered with food have a decrease in rate but not in extent of absorption, meclofenamic acid is decreased in both. It has been reported that following the administration of meclofenamic acid capsules one-half hour after a meal, the average extent of bioavailability decreased by 26%, the average peak concentration (Cmax) decreased fourfold and the time to Cmax was delayed by 3 hours.
Other metabolites, whose excretion rates are unknown, account for the remaining 35% to 62% of the dose excreted in the urine. The remainder of the administered dose (approximately 30%) is eliminated in the feces (apparently through biliary excretion). Trace amounts of meclofenamate sodium are excreted in human breast milk.
