Advantages of sublingual/buccal delivery systems involve: The prescription drugs dissolve speedily and therefore are absorbed with the mucous membranes of the mouth into the systemic circulation.
The doc discusses the Biopharmaceutical Classification System (BCS), which classifies drug substances primarily based on their aqueous solubility and intestinal permeability. The BCS categorizes drugs into four lessons and can be utilized to guideline formulation strategies.
Lozenges are usually used for area slow release of demulcents, anaesthetics and cough cures while in the mouth/pharynx.
