Mefenamic acid, an anthranilic acid derivative, is a member of the fenamate group of nonsteroidal anti-inflammatory drugs (NSAIDs). It exhibits anti-inflammatory, analgesic, and antipyretic activities. Similar to other NSAIDs, mefenamic acid inhibits prostaglandin synthetase.
- 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.
Target Actions Organism AProstaglandin G/H synthase 2 inhibitorHumans UProstaglandin G/H synthase 1 inhibitorHumans - Absorption
Mefenamic acid is rapidly absorbed after oral administration.
- Volume of distribution
- 1.06 L/kg [Normal Healthy Adults (18-45 yr)]
- Protein binding
90%
- Metabolism
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.
Hover over products below to view reaction partners
- Route of elimination
The fecal route of elimination accounts for up to 20% of the dose, mainly in the form of unconjugated 3-carboxymefenamic acid.3 The elimination half-life of mefenamic acid is approximately two hours. Mefenamic acid, its metabolites and conjugates are primarily excreted by the kidneys. Both renal and hepatic excretion are significant pathways of elimination.
- Half-life
2 hours
- Clearance
- Oral cl=21.23 L/hr [Healthy adults (18-45 yrs)]

interactions in your softwareAbacavir Mefenamic acid may decrease the excretion rate of Abacavir which could result in a higher serum level. Abametapir The serum concentration of Mefenamic acid can be increased when it is combined with Abametapir. Abatacept The metabolism of Mefenamic acid can be increased when combined with Abatacept. Abciximab The risk or severity of bleeding and hemorrhage can be increased when Mefenamic acid is combined with Abciximab. Abiraterone The serum concentration of Mefenamic acid can be increased when it is combined with Abiraterone. - Food Interactions
