Abstract:  The stability of dalteparin 1,000 units/mL in 0.9% sodium chloride for injection stored in polypropylene syringes under refrigeration was examined. Dalteparin 1,000-units/mL syringes were prepared by adding 9 mL of 0.9% sodium chloride for injection to 1 mL of dalteparin sodium 10,000 unit/mL from commercial single-use syringes. Compounded solutions in 0.5-mL aliquots were transferred to 1-mL polypropylene syringes and sealed with a Luer lock tip cap and stored at refrigerated temperatures (2°C to 8°C) with ambient fluorescent light exposure. Syringes from three batches of dalteparin 1,000 units/mL were potency tested in duplicate by a stability-indicating high-performance liquid chromatography assay using a 0.5-mL sample at specified intervals. Visual and pH testing were performed on each batch. Samples were visually inspected for container integrity, color, and clarity. Samples for pH testing were prepared using a 1:1 dilution of dalteparin 1,000 units/mL in sterile water for injection and underwent duplicate analysis at each time point. High-performance liquid chromatography analyses showed a remaining percent of the initial dalteparin content at day 30 of 94.88% ± 2.11%. Samples remained colorless and clear with no signs of container compromise and no visual particulate matter at each time point. Throughout the 30-day study period, pH values remained within 0.3-pH units from the initial value of 5.84. Dalteparin 1,000 unit/mL in 0.9% sodium chloride for injection, packaged in 1-mL polypropylene syringes was stable for at least 30 days while stored at refrigerated conditions with ambient fluorescent light exposure.
