The seminar outlines different GRDDS technologies like floating, swelling, mucoadhesive, and significant density systems.

Some important advantages of these routes include quick onset of action, avoidance of 1st-pass metabolism, and enhanced bioavailability in excess of oral delivery. Delivery solutions contain liquid formulations, metered-dose pumps, dry powder inhalers, and nebulizers. In general, the doc outlines the anatomical options and absorption pathways within the nose and lungs, and testimonials distinct systems for providing drugs by way of these
