Abstract

Background: Intraperitoneal (IP) administration of ceftazidime is recommended for the treatment of peritoneal dialysisassociated peritonitis (PDAP) from Pseudomonas. Patients with PDAP may also need IP heparin to overcome problems with drainage of turbid peritoneal dialysis (PD) fluids and blockage of catheters with fibrin. Physico-chemical stability of ceftazidime and heparin, and biological stability of heparin in many types of PD solutions is unknown. Therefore, we investigated the stability of ceftazidime and heparin in 4 types of PD solutions.

Methods: A total of 12 PD bags (3 for each type of solution) containing ceftazidime and heparin were prepared and stored at 4C for 120 hours, and then at 25C for 6 hours, and finally at 37C for 12 hours. An aliquot was withdrawn after predefined time points and analyzed for the concentration of ceftazidime and heparin using high-performance liquid-chromatography (HPLC). Samples were assessed for pH, color changes, particle content, and anticoagulant activity of heparin.

Results: Ceftazidime and heparin retained more than 91% of their initial concentration when stored at 4C for 120 hours followed by storage at 25C for 6 hours and then at 37C for 12 hours. Heparin retained more than 95% of its initial activity throughout the study period. Particle formation was not detected at any time under the storage conditions. The pH and color remained essentially unchanged throughout the study.

Conclusions: Ceftazidime-heparin admixture retains its stability over long periods of storage at different temperatures, allowing its potential use for PDAP treatment in outpatient and remote settings.
