Studies on film coating technolgy of Xiaoliu tablets

Objective To optimize the best technological conditions for the film coating of Xiaoliu tablets.Methods The orthogonal design with disintegration time and the rate of qualified appearance as the index of evaluation was used to test and optimize the best technological conditions.Results The optimum factors were as follows:the hardness of the pets were 40~50 N,the rotational speed of the coating pot was 30 r/min and the temperature was 30℃ for Xiaoliu tablets.Conclusion The film coating method is proved to be suitable,which can be used for the film coating of Xiaoliu tablets.
