“Nevertheless, offered the complexities from the human system, physiology, and chemical/biological interactions that take place, it could be tough to solely trust in the dissolution test being a means of predicting how a drug formulation could perform in vivo
If the basket is reactive with the dosage form then it may be coated with PTFE or an inert material such as gold or titanium.
Such measures can dramatically improve the precise execution on the dissolution test, thus boosting the chance assessments from the dosage forms and ensuring their successful drug launch. Below are a few methods for troubleshooting:
