A dissolution test for coumarin tables was developed and validated. To establish a dissolution procedure various trials have been done in different pH and in stirring speeds and drug release was analyzed by previously validated UV spectrophotometric method. After selection of the best conditions, the method was validated using USP Apparatus II (paddle), 75-rpm rotation speed, 900 mL of phosphate buffer pH 6.8, and test time of 45 min. Previously the developed analytical method was validated for accuracy, precision and recovery studies. Statistical analysis proved that the method was precise, reproducible, selective, specific, and accurate for the analysis of coumarin.
