Analysis is important in every product and it is vital in medicines as well given that our lives are affected by them. The assurance of quality is achieved through analysis of the drug product. Nowadays, the pharmaceutical dosage formed of combinational drugs are very much useful in multiple therapies, rather than the use of single drug formulation because of multiple action, fewer side effects and quicker relief. Thus, the manufacturers market more or more complex formulation containing several drugs in very similar chemical behavior.

The present book titled "Design and Development of Sustained Release Tablet" describes about a novel approach to design and develop such a sustained release matrix tablet formulation which will prove to be advantageous in many aspects. The formulation is possible with the help of an optimized blend of polymers and suitable and compatible excipients. The formulation aspect proves to be advantageous over conventional tablet dosage form. Emphasis has been given on true evaluation of the prepared matrix tablet which assures about the promising future perspective for such matrix tablet formulation...
