Overview
Mefenamic acid, also known as anthranilic acid, is a non-steroid anti-inflammatory drug (NSAID) used to relieve mild and moderate pains. It has antipyretic (fever-reducing) and analgesic (pain-reducing), and anti-inflammatory (reduces swelling) properties.
- It was initially released as early as 1962 for pharmaceutical purposes and was largely marketed then by Parke, Davis and Company.
- While the generic name of this pharmaceutical agent is mefenamic acid, it is better known in its brand form - Meftal spas.
- Mefenamic acid is an anthranilic acid derivative (fenamates) in NSAIDS. Similar to various other NSAIDs, mefenamic acid is generally well tolerated, but could also generate side effects.
- Mefenamic acid’s anti-inflammatory properties are low when compared with other pain relievers, especially during abnormal bleeding during periods.

Meftal spas mechanism of action
Meftal spas sticks to prostaglandin synthetase inhibitors (PGSIs), namely COX-1 And COX-2 (cyclooxygenase) receptors which prohibits the synthesis of prostaglandin, the compound that is responsible for pain.
Prostaglandin is a precursor to the production of pain. Mefenamic acid prohibits the synthesis of prostaglandin by binding with cyclooxygenase receptors, thus reducing pain.

Side effects of meftal spas on specific organs

- Skin: It may cause skin reactions such as reddening or blistering of the skin

- It may cause flu-like symptoms.
Various studies demonstrated that transient serum aminotransferase elevations (indications of hepatotoxicity) are seen in only 5% of patients or less who are administered with mefenamic acid.
Serum aminotransferase is the enzyme that is majorly produced in the liver apart from other organs, and their elevations in blood could depict information about the function of the liver and the extent of damage, the disease progression, or the response to treatment.
These studies further demonstrate that the abnormality usually resolved on its own, devoid of any modification in the dose. Despite the above information, it is always recommended to rush to a doctor in case of any mefenamic acid-induced hepatotoxicity.
