Abstract: Objective:To compare the dissolution of loratadine tablets or capsules in vitro from five different pharmaceutical facto- ries and give suggestions for clinical use.Methods:The dissolution tests were carried out with rotating basket and the content of lorata- dine was determined by UV spectrophotometry.The accumulation dissolution percent was calculated and Weibull formula was used to fit the deta.The dissolution parameters was statistically analyzed by variance analysis and Q test.Results:The dissolution of loratadine tablets or capsules in vitro from five factories were all in conformity with Chinese Pharmacopoeia(2005 edition).But significant differ- ences of dissolution parameters m,Kr,T30,T50,Td and T80 were found among the loratadine tablets or capsules from five factories(P<0.05).Conclusion:There is a significant difference in dissolution parameters of the loratadine tablets or capsules from five factories, indicating that attention should be paid to their difference in clinical use.
