Overview on Osmotically Controlled Drug Delivery System

Novel drug delivery systems (NDDS) constitute the mainstay of pharmaceutical research and development. A significant milestone in oral NDDS is the development of the osmotic drug delivery system, an innovative and highly versatile drug delivery system. Osmotic drug delivery systems utilize the principle of osmotic pressure, as an energy source, for the delivery of drugs. Oral osmotic drug delivery systems with their versatility and their highly predictable drug release rates offer various biomedical advantages. Osmosis is an aristocratic phenomenon that seizes the attention for its exploitation in zero-order drug delivery systems. Osmosis is physical phenomenon that has been comprehensively studied by scientist in various disciplines of science and engineering. Osmotic devices are the most promising strategy based system for controlled delivery of drug.
