Controlled drug release in formulation is an important area of research. Formulations using crospovidone as super-disintegrants to achieve immediate release once it reaches the ileo-cecal region is relevant. The Eudragit L30D pH dependent polymer that allows drug release after a lag time of 4-5 hrs to achieve desired lag time and drug release from current drug delivery system is critical. Pre-formulation to investigate drug-polymer interaction is essential. The linear correlation between the predicted and actual values for all the batches of optimization with high correlation coefficient r-value is shown. Therefore, the designed formulation is promising for ileo-cecal targeted pulsatile drug delivery system in the management of Crohn’s disease.



Budesonide Crohn’s disease, lag time, crospovidone, 32 factorial designs.
