Pharmacokinetics

Diclofenac has rapid absorption, extensive protein binding, and a short t/2 (Table 26-2). There is a substantial first-pass effect, such that only -50% of diclofenac is available systemically. Diclofenac accumulates in synovial fluid after oral administration, which may explain why its duration of therapeutic effect is considerably longer than the plasma t1/2. Diclofenac is metabolized in the liver by a member of the CYP2C subfamily to 4-hydroxydiclofenac, the principal metabolite, and other hydroxylated forms; after glucuronidation and sulfation the metabolites are excreted in the urine (65%) and bile (35%).
