Stability of the Compound Ciprofloxacin Injection was observed and its period of validity was determined so as to supply scientific proof to the clinical application of the preparation. The content of Ciprofloxacin Hydrochloride in Compound Ciprofloxacin Injection was measured by UvVis at 272 nm. Light stability experiments and classical heat stability experiments were taken. The time that content of the preparation was decomposed that of the initial 10% is period of validity of the preparation. The Compound Ciprofloxacin Injection is unstable to light. The resoluble rate constant K is 9.9×10－8 min－1 at room temperature (25 ℃), and the content of Ciprofloxacin Hydrochloride in Compound Ciprofloxacin Injection was reduced that of the initial 10% is 2.025 years. The period of validity of the Compound Ciprofloxacin Injection is 2 years stored under room-temperature (25 ℃) without light.
