Present book provides detailed information on osmotic drug-delivery
systems. Development and characterization aspects of elementary osmotic
pump tablets are explained this book. Such delivery systems are based on
the principle of osmosis. Osmosis refers to the process of movement of
solvent from lower concentration of solute towards higher concentration
of solute across a semi-permeable membrane. These delivery systems are
also ideal for zero order drug release. This book may be helpful for
U.G. and P.G. students for their project work.
