The document discusses many routes of drug administration like topical, enteral, and parenteral routes. It then focuses on controlled drug delivery systems and describes differing types of controlled release mechanisms together with dissolution, diffusion, osmotic force systems, and Some others.
Ways to growth contain polymer membrane systems, polymer matrix systems, and adhesive or microreservoir systems. New strategies talked over are iontophoresis and electroporation, which use electric existing to boost skin permeation.
Buccal drug delivery systems give a promising route for drug administration. They allow drugs to bypass 1st-go metabolism by absorbing in the buccal mucosa in the systemic circulation by way of the facial veins.
