Objective: To prepare osmotic pump controlled release tablets of panax notoginoside. Method: The factor influencing the drug release was investigated by the single factor; orthogonal design was used to get the quantitative relationship among the release. Result: The drug release profile in vitro was influenced by membrane weight and the amount of PEG400. The optimum formulation was: PEG400 90%
NaCl 30%
and the membrane weight 5%(as the percent of the core). Conclusion: The panax notoginoside osmotic pump tablets are attainable by constant speed delivery.
