Abstract

The impact of hydrodynamics and media composition on nifedipine dissolution profile from IR (immediate release) soft capsules was investigated using dissolution apparatus USP1, USP2, USP3 and USP4 (United State Pharmacopoeia). Media composition was varied in terms of pH and content, to mimic the dosage form intake with water or non-alcoholic beverages (orange juice) and alcoholic beverages (orange juice/ethanol mixture (47% v/v)). Through construction of in vitro–in vivo correlations (IVIVC) with corresponding in vivo data from the literature, it was possible to evaluate the in vitro conditions that are likely to simulate the in vivo formulation behaviour. Both linear and nonlinear correlations were obtained depending on experimental set-ups. Testing of 20 mg nifedipine capsules in FaSSGFst (Fasted State Simulated Gastric Fluid pH 1.6; water administration) produced IVIVC with the USP3 (after time scaling) and USP4 apparatus. IVIVC were obtained for USP2, USP3 and USP4 in FaSSGFoj (Fasted State Simulated Gastric Fluid pH 3.4; orange juice administration). Linear and nonlinear correlations were obtained with the USP1, USP2 and USP3 apparatus when testing the capsules in FaSSGFoj/EtOH (orange juice/ethanol administration). This study highlighted that selection of physiologically relevant dissolution set-ups is critical for predicting the in vivo impact of formulations co-administration with water, non-alcoholic and alcoholic beverages.
