    Main Results:

    • One lot exhibited complete dissolution within the specified timeframe.
    • For the remaining four lots, the reproducibility was 2.6% of label claim.
    • The repeatability of the method was 1.6% of label claim across laboratories.

    Conclusions:

    • USP Apparatus 2 is a reliable method for evaluating prednisone tablet dissolution.
    • The dissolution testing method shows acceptable variability for quality control.
    • The study confirms the suitability of the method for ensuring prednisone tablet quality.
