Mefenamic acid undergoes metabolism by CYP2C9 to 3-hydroxymethyl mefenamic acid, and further oxidation to a 3-carboxymefenamic acid may occur. The activity of these metabolites has not been studied. Mefenamic acid is also glucuronidated directly.

The fecal route of elimination accounts for up to 20% of the dose, mainly in the form of unconjugated 3-carboxymefenamic acid.3 The elimination half-life of mefenamic acid is approximately two hours. Mefenamic acid, its metabolites and conjugates are primarily excreted by the kidneys. Both renal and hepatic excretion are significant pathways of elimination.

摘要 甲芬那酸钠、钾和钙盐的通式为 [Na(mef)(H 2 O) 2 ] n · n H 2 O, [K(mef)(H 2 O)] n 和 [Ca(mef) ) 2 (H 2 O) 2 ] n·n H 2 O 已合成,通过 X 射线晶体学、 1 H 和 13 C NMR 和红外光谱研究。复合盐在空气中稳定且可溶于水。在加热过程中,Na 和 K 络合物在络合水中熔化,然后以无水形式重结晶。在固态下,所有的盐都会产生一维配位聚合物。Na、K 和 Ca 配合物的中心原子分别为 5、6 和 7 个配位原子。在所有结构中都存在OH⋯O、NH⋯O和CH⋯O氢键。在实验结果和量子力学计算的基础上,对甲芬那酸及其三配位高分子化合物进行了振动分析。理论和实验振动频率相似,并揭示了所有 IR 有源振荡器的特征振动。在盐的红外光谱中,在约 羧酸根基团的典型值为 1365 和 1600 cm -1。
In this study, the electrochemical oxidation of mefenamic acid was investigated in the presence of glutathione and N-acetyl-L-cysteine. The results revealed that the mefenamic acid was involved in a catalytic reaction with glutathione and N-acetyl-L-cysteine. This investigation presents some electrochemical evidence for the mechanism of action of these compounds in mefenamic acid poisoning. (c) 2020 The Electrochemical Society ("ECS").
