Abstract
Background Intraperitoneal daptomycin is used for the treatment of peritoneal dialysis (PD)-associated peritonitis caused by vancomycin-resistant bacteria. This study investigated the stability of daptomycin in a pH-neutral PD solution.
Methods Reconstituted solution of daptomycin was added to a total of nine PD bags to obtain a concentration of 20 mg/L and stored at 1 of 3 different temperatures: 4 or 25°C for up to 168 h or 37°C for up to 48 h. Stabilities were determined by visual inspection, pH measurement and high-performance liquid chromatography.
Results Daptomycin retained more than 90% of its initial concentration for 120, 72 and 12 h at 4°C, 25°C and 37°C, respectively. No physical precipitation or pH change was observed during the study.
Conclusions Daptomycin in a pH-neutral PD solution is physically and chemically stable for 120 and 12 h at 4°C and 37°C, respectively.
