Stability of guanxinning injection in two injections

Aim To study the stability of guanxinning injection in 5% glucose solution and sodium chloride solution.Methods Guanxinning injection was mixed with 5% glucose injection and sodium chloride injections respectively according to the ratio of 20∶ 500,40∶ 500（5%GS）,10∶ 100,20∶ 100（NS）（v/v）.The appearance,pH,insoluble particles,UV and bacterial toxins limited of the mixture were determined within 4h by the methods described in Chinese Pharmacopoeia（2005）.Results The appearance and UV of mixed solutions had no significant change and bacterial toxin accord with Pharmacopoeia standards,but pH value and particulate matter showed change significantly.Conclusion The phenomena must be noticed on the increase of insoluble particles and the decrease of glucose after guanxinning injection and 5% glucose injection,sodium chloride injection were mixed in different ratios.
