Ang Mefenamic acid o Asidong mefenamiko ay isang miyembro ng klaseng deribatibong asidong anthraniliko (o fenamate) ng mga gamot NSAID. Kadalasan itong ginagamit na panlunas sa kaunti hanggang katamtamang kirot, kasama na ang kirot dulot ng sapanahon o pagreregla, at ginagamit rin para malunasan ang mga sakit ng ulo na kaugnay ng pagreregla.^[1]^[2] Hindi ito malawakang ginagamit dahil sa mga naitatalang kasamang epekto.^[3]^[4]^:334

Natuklasan at naibenta ito sa pamilihan ng Parke-Davis noong dekada ng 1960 sa ilalim ng pangalang Ponstan, Ponalar, Ponstyl, at Ponstel. Naging heneriko ito noong dekada ng 1980 at nagagamit na sa buong mundo sa ilalim ng ibat-ibang pangalan..^[5] Noong 2015, mahigit 200 USD ang halaga ng medikasyon ng mefenamic acid sa Estados Unidos.^[6]

Gamit

Ginagamit ang mefenamic acid upang gamutin ang kaunti hanggang katamtamang kirot at kirot dulot ng sapanahon o pagreregla.^[1] Hindi ito malawakang ginagamit.^[3]^[4]^:334

Kasamang epekto

Nirerekomenda na kumain muna bago uminom ng mefenamic acid.^[7]

Kasama sa mga kilalang kaunting kasamang epekto ng mefenamic acid ang pagsakit ng ulo, pagiging balisa at pagsusuka. May mga malalalang kasamang epekto rin ito tulad na lamang ng diarrhea, hematemesis (pagsusuka ng dugo), haematuria (dugo sa ihi), paglabo ng paningin, pangangati ng balak, sore throat at lagnat.^[4]^:334 Naiugnay rin ito sa talamak na pagkasira sa atay.^[3]

Mekanismo ng aksiyon

Tulad ng ibang miyembro ng klaseng deribatibong asidong anthraniliko (o fenamate) ng gamot NSAID, pinagbabawalan nito ang parehong anyo ng COX at pinipigilan ang pagbuo ng prostaglandins.^[3]^[8]

Pagbuo

Tulad ng sa fenamic acid, ang kompuwestong ito ay maaaring buuin mula sa 2-chlorobenzoic acid at 2,3-dimethylaniline.^[9]
