| Abstract: | Hydroxypropyl methylcellulose (HPMC) was used as the main sustained release excipient of Naoluotong Sustained Release Capsules, and the formula was optimized by the orthogonal experimental design. The optimizing of the formula was done according to the requirements of PRC pharmacopeia and the amount of the accumulative release of ginsenoside was used as a criterion. The results showed that the best formula was composed of 216 mg of HPMC, 24 mg of ethylcellulose and 132 mg of mixed dilutent, and its release curve accorded with Higuchi kinetic model. |
