Abstract:
Objective To investigate the compatibility and room light' s influence on Kuhuang injection diluted by 5%glucose,10% glucose, and fructose for injection within 48 hours at room temperature. Methods Kuhuang injections( high or low dosage) were diluted by 3 solutions at room temperature and were divided into light-exposed group and light-screening group. Stability were then studied by changes of appearance, pH value, particulates, contents of matrine and sophocarpine in the solutions. Results The Kuhuang injection solution remained clear within 48 hours, showing no obvious turbidity, sedimentation or change of appearance ( deep yellow clear solution ) . The pH of the low concentration group with 10% glucose injection exposed to room light in creased significantly at 6 h,which was less stable than the light-screening group.The particulate content was acceptable according to regulation. The Kuhuang injection compatibility solution with fructose injection changed into weak acidic pH, and the particulate content did not meet regulation criteria in the high concentration group. The contents of matrine did not change, while the contents of sophocarpine decreased in each group.Sophocarpine seemed more stable in the light-screening group than in the light-exposed group. Conclusion The fructose injection was not suitable as the solvent for Kuhuang injection.The solutions are more stable if protected from light, and should be used as early as possible to reduce the degradation of some effective components.
