In the recent days, the technology of Mucoadhesive drug delivery system has gained so much attention from the researchers in the field of formulation development. The drug delivery system enables the formulator to bring the drug in the close proximity to the mucus membrane with enhanced contact time and contact area. Thus the technology has been successful to bring out benefits like bio-availability enhancement along with the extended release. The book gives the idea about the basic fundamentals of Mucoadhesive systems. From the presented work, one may get information about the properties of...
