Proceed the testing from the three degrees Except the outcomes of equally acid and buffer phases conform at an previously degree.
This document gives an outline of dissolution testing along with the factors that impact drug dissolution. It defines dissolution and describes the intrinsic dissolution procedure. Furthermore, it discusses the varied apparatus useful for dissolution testing Based on pharmacopeial specs, including the basket, paddle, reciprocating cylinder, and movement-by means of cell.
Decide on from electropolished stainless steel, or several different chemically inert paddles in a range of measurements
