title: [Study on dissolution rate of injection of microencapsulated compound megestrol acetate].
abstract: Dissolution rate of megestrol acetate in the injection of microencapsulated compound megestrol acetate was determined by the first derivative spectrum amplitude method. The experimental results reveal that t50 of the microencapsulated sample (I) is about 60.16 d, while the broken microencapsulated sample (II) is about 15.89 d and the unmicroencapsulated sample (III) about 15.87 d. The difference is regarded as of obvious significance (P less than 0.01). The values of the dissolution rate were linear with the parameters of rabbits and women both in vivo.
