The dissolution test, in its most basic type, inserting the formulation inside of a dissolution apparatus containing appropriate dissolution medium, making it possible for it to dissolved specified period of time then working with appropriate rational technique to determine the amount of drug. Dissolution test are probative and Assessment like drug degradation profile, shelf-existence experiments, stability, Actual physical and mechanical testing of dosage types.
