Abstract
USP dissolution calibrator tablets were analysed by the flow-through cell method with the intention of examining its applicability for the flow-through cell apparatus suitability test. Test was performed with Dissotest CE-6 apparatus, (Sotax, Switzerland) in flow-through cells for tablets and capsules: smaller cells of 12 mm diameter and larger ones of 22.6 mm diameter. Analyses were performed with laminar and turbulent flow of dissolution medium. The flow rates were 16 and 8 ml/min for laminar flow and only 16 ml/min for turbulent flow. From the results it can be concluded that both salicylic acid tablets and prednisone tablets could be used for apparatus suitability test also for the flow-through cell under the conditions of laminar flows of 16 and 8 ml/min in cells φ 12 and 22.6 mm. As regards the turbulent flow of 16 ml/min, without a holder, cells φ 12 mm could be used for salicylic acid tablets and both cells (φ 12 and 22.6 mm) for prednisone tablets.
