{{/items}} {{^items}}Description
A non-steroidal anti-inflammatory agent with analgesic, anti-inflammatory, and antipyretic properties. It is an inhibitor of cyclooxygenase. [PubChem]
Indication
For the treatment of rheumatoid arthritis, osteoarthritis, dysmenorrhea, and mild to moderate pain, inflammation, and fever.
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.
Pharmacokinetics
- Absorption
- Mefenamic acid is rapidly absorbed after oral administration.
- Distribution
- * 1.06 L/kg [Normal Healthy Adults (18-45 yr)]
- 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.
- Elimination
Clearance
* Oral cl=21.23 L/hr [Healthy adults (18-45 yrs)]
