Abstract/OtherAbstract:
PURPOSE: The compatibility and stability of telavancin and vancomycin in heparin or sodium citrate lock solutions were evaluated.
METHODS: Telavancin and vancomycin hydrochloride injection powder lyophilized for solution were reconstituted with 0.9% sodium chloride injection at room temperature according to the manufacturer's instructions and then further diluted with (1) commercially available heparin sodium to reach a final heparin concentration of 2500 units/mL or (2) sodium citrate solution 2.2% or 4% to achieve final telavancin and vancomycin concentrations of 2 and 5 mg/mL. Physical stability, chemical compatibility, and biological anticoagulant stability were analyzed for each antibiotic-anticoagulant combination immediately after preparation and at 24, 48, and 72 hours. Changes in coagulation were measured at each time point and compared using two-way analysis of variance.
RESULTS: Both telavancin and vancomycin retained at least 90% of the initial concentration after incubation at 37 °C over 72 hours. The biological stability of vancomycin 2 mg/mL and telavancin 2 mg/mL did not significantly alter prothrombin time when compared with that of 0.9% sodium chloride injection. However, telavancin 5 mg/mL and vancomycin 5 mg/mL significantly increased the activated partial thromboplastin time at 72 hours compared with the control solution. Visual precipitation only occurred with vancomycin-containing solutions; however, this dissipated after 10 minutes.
CONCLUSION: Telavancin 2 and 5 mg/mL was physically compatible in combination with heparin 2500 units/mL and with sodium citrate 2.2% and 4% over 72 hours. Vancomycin 2 and 5 mg/mL initially precipitated in the sodium citrate 2.2% formulation, but no precipitation was noted after 10 minutes of incubation at 37 °C. Telavancin and vancomycin 2 and 5 mg/mL retained over 90% of the initial concentration after incubation at 37 °C over 72 hours.
