This paper presents the thermodynamic analysis of solubility of gatifloxacin in the N,N-Dimethylformamide (DMF) + methanol (MeOH) cosolvent system at 10 temperatures. From the solubility data, the thermodynamic functions of solution, mixing, and transfers are calculated and analyzed using the Perlovich graphical method. On the other hand, an enthalpy-entropy compensation analysis is performed and the preferential solvation parameters are calculated using the inverse Kirkwood-Buff integral (IKBI) method. The result of the performed calculations indicates that the gatifloxacin solution process is endothermic with entropic favor, where the addition of DMF has a positive cosolvent effect in all cases. Regarding preferential solvation, the results are not entirely conclusive, since in all cases the values of the preferential solvation parameter are less than 0.01, so that, negligible preferential solvation takes place.

Este artículo presenta el análisis termodinámico de la solubilidad de gatifloxacina en el sistema cosolvente de N,N-Dimetilformamida (DMF) + metanol (MeOH) a 10 temperaturas. A partir de los datos de solubilidad se calculan las funciones termodinámicas de solución, mezcla y transferencia. Para el análisis además se utiliza el método gráfico Perlovich. Por otro lado, se realiza un análisis de compensación entalpía-entropía y se calculan los parámetros de solvatación preferencial utilizando el método de las integrales inversas de Kirkwood-Buff (IIKB). Los resultados del análisis termodinámico indican que el proceso de solución de gatifloxacina es endotérmica con favorecimiento entrópico, donde la adición de DMF tiene un efecto cosolvente positivo en todos los casos. En cuanto a la solvatación preferencial, los resultados no son del todo concluyentes, debido a que en todos los casos los valores del parámetro de solvatación preferencial son menores a 0,01 indicando una solvatación insignificante.
