Bioadhesive-based dosage forms: The next generation

Authors


Abstract

Prolonged contact time of a drug with a body tissue, through the use of a bioadhesive polymer, can significantly improve the performance of many drugs. These improvements range from better treatment of local pathologies to improved drug bioavailability and controlled release to enhanced patient compliance. There are abundant examples in the literature over the past 15 years of these improvements using first generation or “off-the-shelf” bioadhesive polymers. The present mini-review will remind us of the success achieved with these first-generation polymers and focus on proposals for the next-generation polymers and attendant benefits likely to occur with these improved polymeric systems. © 2000 Wiley-Liss, Inc. and the American Pharmaceutical Association J Pharm Sci 89: 850–866, 2000
