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.
