This document discusses dissolution testing, which is a crucial quality Manage treatment for pharmaceutical dosage types. It commences by introducing dissolution testing and detailing that it measures the rate and extent of dissolution of a drug products less than specified circumstances. It then describes the different apparatus utilized for dissolution testing according to official compendia just like the USP, such as the basket, paddle, reciprocating cylinder, movement-as a result of mobile, paddle-more than-disk, rotating cylinder, and reciprocating disk methods.
