Resumen

La solubilidad de los medicamentos en sistemas de cosolventes de interés farmacéutico es de gran importancia para entender y optimizar una gran cantidad de procesos. Aquí, reportamos la solubilidad de la isoniacida en nueve mezclas de cosolvente (PEG 200 + agua) a nueve temperaturas (278.15, 283.15, 288.15, 293.15, 298.15, 303.15, 308.15 y 318.15 K), determinada mediante espectrofotometría UV-vis. A partir de los datos de solubilidad, se calcularon las funciones termodinámicas de solución, mezcla y transferencia, además de realizar el análisis de compensación entalpía-entropía. La solubilidad de la isoniacida depende de la concentración de PEG 200 (efecto cosolvente positivo) y de la temperatura (proceso endotérmico), alcanzando su máxima solubilidad en PEG 200 puro a 318.15 K y la menor solubilidad en agua pura a 278.15 K. El proceso de solución se ve favorecido por la entropía de la solución y, según el análisis de compensación entalpía-entropía, está impulsado por la entropía en las mezclas ricas en agua y por la entalpía en las mezclas ricas en PEG 200

The solution process is favored by the solution entropy and according to the enthalpy–entropy compensation analysis it is driven by entropy in mixtures rich in water and by enthalpy in mixtures rich in PEG 200.",
