Development and Validation of In Vitro Discriminatory Dissolution Testing Method for Fast Dispersible Tablets of BCS Class II Drug
Journal Title: Turkish Journal of Pharmaceutical Sciences - Year 2020, Vol 17, Issue 1
Abstract
Objectives: Fast dispersible tablets (FDTs) get dispersed very fast due to which the discrimination of in vitro drug release and their evaluation is difficult. Hence in the present study a new in vitro discriminatory dissolution method was developed and validated for FDTs of domperidone of BCS class II. Materials and Methods: FDTs of domperidone were prepared by direct compression method. The dissolution studies were performed in an eight-station Electrolab TDT-082 dissolution testing apparatus, analyzed by ultraviolet spectrophotometer and evaluated in different dissolution mediums i.e. sodium lauryl sulphate (0.5%, 1.0% and 1.5%) with fresh distilled water, simulated intestinal fluid pH 6.8, simulated gastric fluid pH 1.2 without enzymes, phosphate buffer solution (pH 6.8) and 0.1 N hydrochloric acid at different agitation speeds. Results: The developed method was validated in terms of specificity, accuracy, precision, linearity and robustness. Amongst the different mediums, 0.5% sodium lauryl sulfate (SLS) with distilled water was found to be optimum with higher rate of discriminatory power. The percentage recovery was found to be 96 to 100.12 % and the % relative standard deviation value for precision (intraday and interday) was found to be less than 1%. Also a dissolution profile of prepared FDTs were compared in distilled water containing 0.5% SLS using similarity (f2) and dissimilarity (f1) factor calculation which showed dissimilarity in release profile and confirms the discriminatory nature of developed method. Conclusion: The discriminatory dissolution method for FDTs was developed and validated. All the obtained results were satisfactory, accurate and in range. The current method could be beneficial for formulation development and for assessment of quality of FDTs.
