| Summary: | Mefenamic acid is an NSAID used in short term pain management. Mefenamic acid has poor solubility,
and improving its solubility is deemed essential to increase efficacy. Forming an eutectic mixture with
a coformer is a method known to increase the solubility of poorly soluble APIs. In this study, the
formation of eutectics of mefenamic acid, sodium mefenamate, and potassium mefenamate with Lproline as a coformer is observed, and the increase in solubility is predicted. Sodium and potassium
salts of mefenamic acid are formed. Then, eutectic mixtures are formed between the three active
compunds with L-proline using the neat grinding method. The formed salts and eutectic mixtures are
characterized using electrothermal analysis, FT-IR, and DTA/TG. Then, a literature study was done to
predict the solubility improvement of the formed eutectic mixtures. Electrothermal analysis dan FT-IR
analysis confirmed the formation of sodium mefenamate and potassium mefenamate. Screening by
electrothermal method showed eutectic points at 4:6 molar ratio for MFA-LPR, 6:4 for NaMFA-LPR,
and 4:6 for KMFA-LPR. FT-IR analysis on the formed eutectic mixture showed no new peaks in the
spectra of MFA-LPR, NaMFA-LPR, and KMFA-LPR eutectic mixtures. DTA/TG analysis showed that Lproline lowered the melting point of MFA-LPR (1:1) to 174,2°C, NaMFA-LPR (1:1) to 116,2°C and 124°C,
and KMFA-LPR (1:1) to 126,3°C. The data shows that the mixture is an eutectic mixture. Literature
study showed that eutectic mixtures with L-proline as a coformer showed good potential to increase
the solubility of mefenamic acid, sodium mefenamate, and potassium mefenamate. In conclusion, an
eutectic mixture formed between mefenamic acid, sodium mefenamate, and potassium mefenamate,
and the formation of eutectic mixtures was found to have the potential to increase the solubility of
mefenamic acid.
