Mefenamic acid (CAS NO.61-68-7) is a non-steroidal anti-inflammatory drug, so it can be used to treat pain, including menstrual pain, also ot is typically prescribed for oral administration. However, it decreases inflammation (swelling) and uterine contractions by a still unknown mechanism and it is thought to be related to the inhibition of prostaglandin synthesis.

Mefenamic acid , its cas register number is 61-68-7. It also can be called Mefenamic acid [USAN:INN:BAN:JAN] ; 2-((2,3-Dimethylphenyl)amino)benzoic acid ; 2-Diphenylaminecarboxylic acid, 2',3'-dimethyl- ; Ac. mefenamico ; Ac. mefenamico [Italian] ; Acide mefenamique ; Acide mefenamique [French] ; Acide mefenamique [INN-French] ; Acido mefenamico ; Acido mefenamico [INN-Spanish] ; Acidum mefenamicum ; Acidum mefenamicum [INN-Latin] ; Anthranilic acid, N-2,3-xylyl- ; Bafhameritin-M ; Benzoic acid, 2-((2,3-dimethylphenyl)amino)- ; Benzoic acid, 2-(2,3-dimethylphenyl)amino- ; Bonabol ; Fenamin ; HL 1 ; Lysalgo ; Mefacit ; Mefedolo ; Mefenamate ; Mefenamic acid ; Mefenaminsaeure ; Mephenamic acid ; Mephenaminic acid ; Methenamic acid ; Mycasaal ; N-(2,3-Dimethylphenyl)anthranilic acid ; N-(2,3-Xylyl)-2-aminobenzoic acid ; N-2,3-Xylylanthranilic acid ; Namphen ; Parkemed ; Ponalar ; Ponstan ; Ponstan forte ; Ponstel ; Rolan ; Tamany Bonsan ; Tanston ; Vialidon . It is a light yellow solid. Since it plays a significant role in mefenamic acid elimination, patients with known liver deficiency may be prescribed lower doses. Kidney deficiency may also cause accumulation of the drug and its metabolites in the excretory system. Therefore patients suffering from renal conditions should not be prescribed mefenamic acid.
