In addition, it handles terminology, drug candidates suited for modified dosing, clinical considerations, and FDA/USP rules concerning screening, labeling As well as in vitro-in vivo correlations. The objective of those dosage forms is to reduce dosing frequency while maintaining therapeutic drug stages as time passes.

This document discusses controlled drug delivery systems. It begins by defining controlled drug delivery systems and their aim of releasing therapeutic doses of a drug in the desired spot and period of time. It then discusses a variety of varieties of modified release dosage forms like sustained release, extended release, and controlled release.
Sustained release tablets have quite a few benefits but these have some negatives together with slower therapeutic effect as compared with speedy release tablets and it's got complicated formulation and higher manufacturing Price.
