The dimensions with the paddle are closely controlled. Any variants can certainly have a harmful effect on reproducibility from vessel to vessel.
This document provides an summary of dissolution testing as well as factors that affect drug dissolution. It defines dissolution and describes the intrinsic dissolution process. In addition it discusses the varied apparatus used for dissolution testing according to pharmacopeial requirements, such as the basket, paddle, reciprocating cylinder, and circulation-by means of cell.
Find from electropolished stainless steel, or several different chemically inert paddles in A selection of sizes
Prosolv EASYtab SP was integrated while in the formulation as Tremendous disintegrant. The amount of Precirol ATO 5 and ethyl cellulose experienced a substantial impact on drug release in sustained-release minitablet. The strategy can be beneficial from the industry.
