Abstract:
OBJECTIVE: To compare the in vitro dissolution of carvedilol tablets from four different pharmaceutical factories for references of clinical application of carvedilol tablets. METHODS: The dissolution test was carried out with basket-rotating method. The content of carvedilol was determined by UV spectrophotometry. The accumulative dissolution percentage was calculated. The Weibull’s equation was used to fit the dissolution parameters including T50,Td,T80,and m. Then an ANOVA was performed on these parameters. RESULTS: The dissolution of carvedilol from four manufactories conformed to the requirements of Chinese Pharmacopoeia(2005 edition). But significant differences were found among carvedilol preparations from different factories in dissolution parameters including m,T50,Td and T80(P
