Mefenamic acid Chemical Properties,Uses,Production


Mefenamic acid is a kind of nonsteroidal anti-inflammatory (NSAID) drug belonging to the anthranilic acid derivatives class. It is mainly used for the short-term treatment of mild to moderate pain from various conditions. It is also used for reducing the pain and blood loss from menstrual condition as well as prevention of migraines. Moreover, it may also be used for treating gout attacks. Its mechanism is through inhibiting both the isoforms of COX and preventing the formation of prostaglandins. It is manufactured from 2-chlorobenzoic acid and 2,3-dimethylaniline. 


Chemical Properties

Light Yellow Solid


For the treatment of rheumatoid arthritis, osteoarthritis, dysmenorrhea, and mild to moderate pain, inflammation, and fever.


Anti-inflammatory; analgesic.


Mefenamic acid (Ponstel) is indicated only for analgesia and primary dysmenorrhea when therapy will not exceed 1 week.


ChEBI: An aminobenzoic acid that is anthranilic acid in which one of the hydrogens attached to the nitrogen is replaced by a 2,3-dimethylphenyl group. Although classed as a non-steroidal anti-inflammatory drug, its anti-inflammatory properties are considered to b minor. It is used to relieve mild to moderate pain, including headaches, dental pain, osteoarthritis and rheumatoid arthritis.

brand name

Ponstel (Sciele).

General Description

Mefenamic acid (Ponstel, Ponstan) is one of the oldestNSAIDs, introduced into the market in 1967 for mild tomoderate pain and for primary dysmenorrhea. It is rapidly absorbed with peak plasma levels occurring 2 to 4 hoursafter oral administration. It undergoes hepatic benzylic hydroxylationof its 3'methyl group regioselectively into twoinactive metabolites, 3'-hydroxymethylmefenamic acid andthe 3'carboxylate metabolite (via further oxidation of thebenzylic alcohol group). The parent drugs and these metabolitesare conjugated with glucuronic acid and excreted primarilyin the urine. Thus, although patients with knownliver deficiency may be given lower doses, it is contraindicatedin patients with preexisting renal dysfunction.
Common side effects associated with its use include diarrhea,drowsiness, and headache. The possibility of blood disordershas also prompted limitation of its administration to 7days. It is not recommended for children or during pregnancy.
