Application
An NSAID. Circumvents MRP-mediated multidrug resistance. Specifically and significantly potentiates the cytotoxicity of anthracyclines as well as teniposide, VP-16 and vincristine.
Mefenamic acid has been used:
- to test its hepatotoxic effect in the transgenic zebrafish cell line (LiPan)
- to test its neuroprotective functionality in zebrafish embryos/larvae
- in the preparation of mucoadhesive microparticles in hydrogel beads
Biochem/physiol Actions
Mefenamic acid is an analgesic and anti-inflammatory drug. It acts as a cyclooxygenase (COX) enzyme inhibitor. It is hepatoxic and implicated in liver injury. Contrarily, mefenamic acid elicits neuroprotection in in vivo ischemic stroke models by inhibiting cell toxicity induced by glutamate. Mefenamic due its inhibitory effect on prostaglandin synthesis can be used in reducing edema and ache.

Menorrhagia is a common problem, yet evidence to inform decisions about therapy is limited. In a pragmatic, multicenter, randomized trial, we compared the levonorgestrel-releasing intrauterine system (levonorgestrel-IUS) with usual medical treatment in women with menorrhagia who presented to their primary

Mefenamic acid, (MFA), a carboxylic acid-containing nonsteroidal anti-inflammatory drug (NSAID), is metabolized into the chemically reactive conjugates MFA-1-O-acyl-glucuronide (MFA-1-O-G) and MFA-S-acyl-CoA (MFA-CoA), which are both implicated in the formation of MFA-S-acyl-glutathione (MFA-GSH) conjugates, protein-adduct formation, and thus the potential toxicity
