Stability of intravenous famotidine stored in polyvinyl chloride syringes.
The stability of intravenous famotidine in dextrose 5% injection (D5W), NaCl 0.9% injection (NS), and sterile water for injection stored in polyvinyl chloride (PVC) syringes at 4 degrees C for 14 days was studied. The concentration of famotidine samples was determined at time 0, 7 days, and 14 days by reverse-phase high-performance liquid chromatography. Samples were inspected for visual changes and tested for changes in pH. Results of the HPLC analysis indicated that the famotidine samples remained within 94-100 percent and 99-103 percent of the time 0 concentrations at 7 and 14 days, respectively. Repeated measures analysis of variance demonstrated a significant time effect on famotidine concentration as concentrations changed over time (p less than 0.01). This change was small in magnitude, however, and concentrations decreased at 7 days and increased at 14 days. Famotidine is stable at a concentration of 2 mg/mL in D5W, NS, and sterile water for injection stored in PVC syringes at 4 degrees C for 14 days.
