概要
Meclofenamic acid is an aminobenzoic acid that is anthranilic acid in which one of the hydrogens attached to the nitrogen is replaced by a 2,6-dichloro-3-methylphenyl group. A non-steroidal anti-inflammatory drug, it is used as the sodium salt for the treatment of dysmenorrhoea (painful periods), osteoarthritis and rheumatoid arthritis. It has a role as a non-steroidal anti-inflammatory drug, an analgesic, an antipyretic, an EC 1.14.99.1 (prostaglandin-endoperoxide synthase) inhibitor, an antineoplastic agent, an anticonvulsant, an antirheumatic drug and an EC 1.13.11.34 (arachidonate 5-lipoxygenase) inhibitor. It is an aminobenzoic acid, an organochlorine compound and a secondary amino compound. It is a conjugate acid of a meclofenamic acid(1-).

PharmacodynamicsMeclofenamic acid is a nonsteroidal agent which has demonstrated anti-inflammatory, analgesic, and antipyretic activity in laboratory animals.
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.
Biological Half-LifeIn a study in 10 healthy subjects following a single oral dose the apparent elimination half-life ranged from 0.8 to 5.3 hours. Metabolite I (3-hydroxymethyl metabolite of meclofenamic acid) has a mean half-life of approximately 15 hours.
Metabolism/Metabolites
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.
MeSH Pharmacological Classification
Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
