Crucial components influencing mucoadhesion are related to the polymer Homes, for instance molecular weight, concentration, adaptability, and spatial conformation, together with environmental and physiological variables. Mucoadhesive systems can offer Added benefits like prolonged drug residence at the location of motion and greater drug absorption.
Some critical advantages of these routes incorporate rapid onset of action, avoidance of to start with-go metabolism, and enhanced bioavailability above oral delivery. Delivery techniques consist of liquid formulations, metered-dose pumps, dry powder inhalers, and nebulizers.
