Development and Characterization of Eudragit EPO-Based Solid Dispersion of Rosuvastatin Calcium to Foresee the Impact on Solubility, Dissolution and Antihyperlipidemic Activity.

Poor solubility is the major challenge involved in the formulation development of new chemical entities (NCEs), as more than 40% of NCEs are practically insoluble in water. Solid dispersion (SD) is a promising technology for improving dissolution and, thereby, the bioavailability of poorly soluble drugs. This study investigates the influence of a pH-sensitive acrylate polymer, EPO, on the physicochemical properties of rosuvastatin calcium, an antihyperlipidemic drug.

Vardenafil Oral Dispersible Films (ODFs) with Advanced Dissolution, Palatability, and Bioavailability.

Comparative studies of the effects of novel excipients amino acids with cyclodextrins on enhancement of dissolution and oral bioavailability of the non-ionizable drug carbamazepine.

Despite significant innovations in pharmaceutical industries, low water solubility is still a common biopharmaceutics-related problem that encounters 40% of marketed pharmaceutical products and results in erratic oral absorption and low bioavailability. Poorly soluble non-ionizable drugs pose additional challenges for enhancing solubility of this class of drugs. The effects of small molecular weight carriers such as amino acids (glycine, L-threonine; L-lysine and aspartic acid) on solubilization and enhancing bioavailability of Carbamazepine (Car) were investigated and compared to the more known excipients cyclodextrins (β-CD, HPβ-CD and γ-CD).
