Abstract:
OBJECTIVE:To establish a method for the dissolution determination of Dronedarone hydrochloride tablet,and eval-uate the quality consistency of its generic and original preparations. METHODS:UV spectrometry was performed on the column of 288 nm,dissolution media of Phosphate buffer solution (pH4.5),0.1 mol/L Hydrochloric acid solution [adding into 0.5% sodium dodecyl sulfate(SDS)],Phosphate buffer solution [pH6.8,adding into 0.5%SDS] and water,volume of dissolution medium was 1 000 ml,rotation speed was 75 r/min,the dissolution of generic and original preparations of Dronedarone hydrochloride tablet was detected,and the similarity of dissolution curve was evaluated by calculating the similarity factor (f2). RESULTS:The linear range of dronedarone hydrochloride was 2.147-25.764 μg/ml;RSDs of precision,stability and reproducibility tests were lower than 2.0%;recoveries 4 dissolution media were 99.53%-101.05%(RSD=0.48%,n=9),98.95%-100.05%(RSD=0.39%,n=9), 99.54%-100.20%(RSD=0.24%,n=9)and 98.54%-100.06%(RSD=0.44%,n=9). In the 4 dissolution media,f2 of the dissolu-tion curve of 3 batches of generic and original preparations of Dronedarone hydrochloride tablet was 56,60,63,68,68,52,59, 67,65,68,76,62,respectively. CONCLUSIONS:The method is suitable for the dissolution determination of Dronedarone hydro-chloride tablet;meanwhile,the in vitro dissolution curves of generic and original preparations of Dronedarone hydrochloride tablet show similarity,so the quality consistency is good.
