Mechanism of Action
Mefenamic acid binds the prostaglandin synthetase receptors COX-1 and COX-2, inhibiting the action of prostaglandin synthetase. As these receptors have a role as a major mediator of inflammation and/or a role for prostanoid signaling in activity-dependent plasticity, the symptoms of pain are temporarily reduced.
- Mefenamic acid is rapidly absorbed after oral administration.
- * 1.06 L/kg [Normal Healthy Adults (18-45 yr)]
- Mefenamic acid undergoes metabolism by CYP2C9 to 3-hydroxymethyl mefenamic acid, and further oxidation to a 3-carboxymefenamic acid may occur. The activity of these metabolites has not been studied. Mefenamic acid is also glucuronidated directly.
