<p>Diclofenac undergoes oxidative metabolism to hydroxy metabolites as well as conjugation to glucuronic acid, sulfate, and taurine.<sup class="text-reference-group"><a class="reference-popover-link" data-content="Official drug label" href="#label-reference">Label</a>,<a class="reference-popover-link" data-content="Davies NM, Anderson KE: Clinical pharmacokinetics of diclofenac.

This metabolite is very weakly active with one thirtieth the activity of diclofenac. Other metabolites include 3'-hydroxy diclofenac, 3'-hydroxy-4'methoxy diclofenac, 4',5-dihydroxy diclofenac, an acylglucuronide conjugate, and other conjugate metabolites.</p><p class="d-none d-sm-block"><strong>Hover over products below to view reaction partners</strong></p>
