This document summarizes a seminar on gastroretentive drug supply techniques (GRDDS). GRDDS are built to retain medication while in the abdomen for prolonged periods of time to allow for sustained drug release. The seminar outlines many GRDDS systems together with floating, swelling, mucoadhesive, and substantial density devices.
On top of that, mini paddles for smaller-volume dissolution testing and Chinese Pharmacopeia procedures can be obtained
The doc discusses compendial methods of dissolution testing In line with pharmacopoeia expectations. It describes the necessity for dissolution testing To guage drug release from stable dosage sorts and guarantee bioavailability. The key compendial apparatuses talked about will be the basket, paddle, stream-as a result of mobile, and dissolution testing solutions for modified launch sorts.
You will find numerous 'Formal' types of dissolution test apparatus, Every with key options and Gains. They involve:
