The amount of zein-hydrocortisone microparticles (mean ± SEM; n = 3) equivalent to a clinically used dose of hydrocortisone (4 mg) for samples prepared using various combinations of hydrocortisone (25–200 mg) and zein (200–800 mg). One-way factorial ANOVA with a post hoc Bonferroni test was used to compare selected means for varying quantities with constant ratio of zein and mesalazine (a–b), and a constant quantity of zein with varying mesalazine quantity (x). The level of significance was set at p < 0.05 and means that were not significantly different were assigned the same letter.
