Abstract

For increasing bioavailability and solubility of Azilsartan Medoxomil (AZM), a modified dosage form was developed in this study. Solid dispersion of Azilsartan Medoxomil was prepared through physical mixture and kneading method with β-cyclodextrin. Characterization is done by two main methods, Differential scanning calorimetry (DSC), and Fourier transform infrared spectroscopy (FTIR). The results confirmed that the use of solid dispersion in the modified dosage forms greatly enhanced the antihypertensive medications solubility and dissolution, which were previously weakly soluble in water. Furthermore, the pharmacokinetic study was performed on Wistar rats after oral administration of pure suspension and Azilsartan solid dispersion. The pharmacokinetic parameters i.e., Cmax and AUC for solid dispersions were reported to be significantly increased (p < 0.05) than that of pure API suspension. The formulation of SD-3 solid dispersion was shown best in improving solubility and dissolution. Overall, the study showed how altered dose forms may enhance the bioavailability and effectiveness of medications that are poorly soluble in water, which may result in better treatment outcomes for hypertension patients
