Description

A non-steroidal anti-inflammatory agent with antipyretic and antigranulation activities. It also inhibits prostaglandin biosynthesis. PubChem (source: Drug Bank)

Indication

For the relief of mild to moderate pain, for the treatment of primary dysmenorrhea and for the treatment of idiopathic heavy menstrual blood loss. Also for relief of the signs and symptoms of acute and chronic rheumatoid arthritis and osteoarthritis. (source: Drug Bank)

ATC Therapeutic Categories

  • M01AG:Fenamates
  • M02AA:Antiinflammatory preparations, non-steroids for topical use

Pharmacology, Interactions, and Contraindications

Mechanism Of Action

The mode of action, like that of other nonsteroidal anti-inflammatory agents, is not known. Therapeutic action does not result from pituitary-adrenal stimulation. In animal studies, meclofenamic acid was found to inhibit prostaglandin synthesis and to compete for binding at the prostaglandin receptor site. In vitro meclofenamic acid was found to be an inhibitor of human leukocyte 5-lipoxygenase activity. These properties may be responsible for the anti-inflammatory action of meclofenamic acid. There is no evidence that meclofenamic acid alters the course of the underlying disease. (source: Drug Bank)

Pharmacology

Meclofenamic acid is a nonsteroidal agent which has demonstrated anti-inflammatory, analgesic, and antipyretic activity in laboratory animals. (source: Drug Bank)

Absorption, Distribution, Metabolism, Elimination & Toxicity

Biotransformation

Hepatic. Meclofenamic acid is extensively metabolized to an active metabolite (Metabolite I; 3-hydroxymethyl metabolite of meclofenamic acid) and at least six other less well characterized minor metabolites. Only Metabolite I has been shown in vitro to inhibit cyclooxygenase activity with approximately one fifth the activity of meclofenamic acid. (source: Drug Bank)

Protein Binding

Greater than 99% bound to plasma proteins over a wide drug concentration range. (source: Drug Bank)

Absorption

Rapidly absorbed in man following single and multiple oral doses with peak plasma concentrations occurring in 0.5 to 2 hours. The concomitant administration of antacids (aluminum and magnesium hydroxides) does not interfere with absorption of meclofenamic acid. Unlike most NSAIDs, which when administered with food have a decrease in rate but not in extent of absorption, meclofenamic acid is decreased in both. It has been reported that following the administration of meclofenamic acid capsules one-half hour after a meal, the average extent of bioavailability decreased by 26%, the average peak concentration (C<sub>max</sub>) decreased fourfold and the time to C<sub>max</sub> was delayed by 3 hours. (source: Drug Bank)

Toxicity

After a massive overdose, CNS stimulation may be manifested by irrational behavior, marked agitation and generalized seizures. Following this phase, renal toxicity (falling urine output, rising creatinine, abnormal urinary cellular elements) may be noted with possible oliguria or anuria and azotemia. A 24 year-old male was anuric for approximately one week after ingesting an overdose of 6 to 7 grams of meclofenamate sodium. Spontaneous diuresis and recovery subsequently occurred.
