It also discusses prospect drugs for GRDDS, benefits like improved bioavailability, and evaluation approaches like dissolution tests, floating time, and mucoadhesive toughness tests. Restrictions involve instability at gastric pH and prerequisite more info of substantial fluid levels for floating systems.
