Stability of octreotide acetate in polypropylene syringes.
The stability of octreotide acetate in polypropylene syringes was studied. Polypropylene syringes were aseptically filled with 1 mL of octreotide acetate 0.2 mg/mL and stored at 3 or 23 degrees C under light protection or light exposure. Three syringes were prepared for each condition and each sampling time. Unopened 5-mL glass vials of the drug served as controls. Samples were removed immediately and at 8, 15, 22, and 29 days and analyzed by high-performance liquid chromatography. At 3 degrees C, octreotide stored in light-protected syringes maintained more than 90% of its initial concentration for up to 29 days. However, at 22 days the concentration in the syringes stored at that temperature and exposed to light was less than 90% when the standard deviation is considered. At 23 degrees C, the drug was stable for only up to 15 days (light protection) and 22 days (light exposure) when the standard deviation is considered. Octreotide acetate in polypropylene syringes was stable for up to 29 days when stored at 3 degrees C and protected from light and for up to 22 days when stored at 23 degrees C and exposed to light.
