Advantages of sublingual/buccal delivery systems include: The medications dissolve promptly and therefore are absorbed through the mucous membranes from the mouth into your systemic circulation.
This document discusses oral sustained and controlled release dosage kinds. It begins with an introduction and overview of rationality in planning sustained release drug formulations. It defines sustained release as formulations that consistently release medication about an extended time period immediately after an individual dose to accomplish prolonged therapeutic results.
Lozenges are historically utilized for area sluggish release of demulcents, anaesthetics and cough remedies from the mouth/pharynx. Capsules are stable device dosage forms made by compressing API with adhesives and various excipients into rounded masses for oral administration.
