The implantable Infusaid drug pump model 100 (Shiley Infusaid, Norwood, Mass.) is undergoing trials as a drug delivery system in the treatment of osteomyelitis. This study evaluated the stability of vancomycin (1 mg/ml) incubated at 37 degrees C for 4 weeks in the pump. Both bioassay and high-pressure liquid chromatography data demonstrated a loss of at least 38% of activity over 4 weeks and colloidal precipitation of vancomycin in the pump at the end of the experiment. This study suggests that vancomycin is not stable enough for use in the Infusaid drug pump model 100.
