This doc summarizes a seminar on gastroretentive drug shipping and delivery methods (GRDDS). GRDDS are created to retain medication in the tummy for extended periods of time to allow for sustained drug launch. The seminar outlines many GRDDS technologies such as floating, swelling, mucoadhesive, and substantial density techniques.
This doc discusses dissolution testing, which is an important high-quality Management procedure for pharmaceutical dosage kinds. It begins by introducing dissolution testing and explaining that it measures the rate and extent of dissolution of the drug product under specified situations. It then describes the varied apparatus utilized for dissolution testing As outlined by Formal compendia just like the USP, including the basket, paddle, reciprocating cylinder, circulation-as a result of cell, paddle-over-disk, rotating cylinder, and reciprocating disk procedures.
If the medium is actually a buffered Remedy, then alter the pH in just 0.05 models on the pH specified in the monograph. The dissolution medium must be De-aerated ahead of testing.
There are actually a number of 'official' types of dissolution test apparatus, Each and every with important capabilities and Positive aspects. They contain:
In addition, it discusses applicant prescription drugs for GRDDS, positive aspects like improved bioavailability, and analysis strategies like dissolution testing, floating time, and mucoadhesive strength testing. Limits involve instability at gastric pH and need of large fluid concentrations for floating methods.
A suitable product for instance a wire of glass helix could possibly be accustomed to retain horizontal at the bottom from the vessel tablets or capsules that may if not float. When Apparatus 2 is used, area the tablet or capsule inside of a dry basket at first of each and every test. Lower the basket into posture just before rotation.
