For an prolonged-release dosage sorts, a minimum of 3 test time factors ordinarily are chosen to characterize the in vitro drug release profile. An early time level, commonly one–two h, is picked out to show that there is small probability of dose dumping (far too much drug product dissolving also shortly). An intermediate time stage is chosen to define the in-vitro launch profile in the dosage kind, plus a ultimate time stage is decided on to indicate the basically total release in the drug.
