Fig. 7From: Optimized chronomodulated dual release bilayer tablets of fexofenadine and montelukast: quality by design, development, and in vitro evaluationThe optimized immediate release tablet layer represented via desirability plot (a, d), correlating response factor plots for drug release (%) (b, e) and disintegration time (seconds) (c, f). SSG, sodium starch glycolate; SB, sodium bicarbonate. The optimized sustained release layer tablet layer represented via desirability plot (g, h) and correlating response factor plots for drug release (%) (i, j). HPMC, hydroxypropyl methylcellulose; MS, magnesium stearateBack to article page
