En estudios preliminares de la preformulación, la evaluación de interacciones en el estado sólido entre un componente activo con diversos excipientes es esencial para garantizar la calidad del producto final. Varias investigaciones han sido realizadas usando la termogravimetría (TG) y la calorimetría exploratoria diferencial (DSC) como una importante herramienta analítica para determinar la compatibilidad del fármaco-excipientes. En este estudio se investigó la interacción entre la teofilina y varios excipientes farmacéuticos (celulosa microcristalina, goma xantana, goma guar, polivinilpirrolidona K-30, Eudragit® L100 y Opadry® Clear) usando termogravimetría (TG) y la calorimetría exploratoria diferencial (DSC). La espectroscopía infrarroja...
