Abstract

The compatibility of ciprofloxacin injection with selected antimicrobials and aminophylline was studied. Ciprofloxacin, amikacin sulfate, aminophylline, clindamycin phosphate, gentamicin sulfate, and tobramycin sulfate were mixed separately in minibags containing 0.9% sodium chloride injection or 5% dextrose injection; admixtures were stored for up to 48 hours at either 4 °C or 25 °C. Ciprofloxacin was also combined separately with each of the other drugs and solutions and stored under the same conditions. In addition, ciprofloxacin was combined with metronidazole in ready-to-use minibags of the latter drug and stored at 25 °C. Drug concentrations were measured by fluorescence polarization immunoassay or high-performance liquid chromatography. All admixtures were also examined visually. Stability was defined as retention of at least 90% of the original drug concentration with no visual evidence of incompatibility. With one exception, drugs in all single-drug admixtures were stable for 48 hours. The drug concentration eight hours after amikacin was mixed in 0.9% sodium chloride and refrigerated was 89% of the original concentration. When ciprofloxacin was combined with gentamicin, metronidazole, or tobramycin, all of the involved drugs were stable for 48 hours. Compatibility of ciprofloxacin-amikacin admixtures depended on the fluid and storage temperature; all such admixtures were stable for at least eight hours. A precipitate formed immediately whenever ciprofloxacin was mixed with clindamycin and within four hours after ciprofloxacin was mixed with aminophylline. Ciprofloxacin injection was compatible with gentamicin, metronidazole, and tobramycin and incompatible with aminophylline and clindamycin. The compatibility of ciprofloxacin-amikacin admixtures depended on the i.v. solution and storage temperature.
