The cisplatin and etoposide had been reported to be an effective anti-tumor drug for small cell lung cancer, ovarian cancer, breast cancer and so on. The aim of this study was to evaluate the stability of cisplatin and etoposide in aqueous solution.
Cisplatin 200 microgram/ml was prepared in 0.9% sodium chloride and stored in either glass bottle or polyvinyl chloride (pvc) bag and protected from light or exposed to fluorescent light. Etoposide solution was prepared in 0.9% sodium chloride, and contained in glass bottle. Precipitating concentration was achieved using 200 microgram/ml, 400microgram/ml, 600 microgram/ml, and 1000 microgram/ml of etoposide solution. Samples were stored at room temperature and visually inspected and assayed for etoposide and cisplatin content by high-performance liquid chromatography after 15 minutes, 2, 4, 8, 12, 16 and 24 hours of storage. RESULT: 1) Cisplatin concentration decreased less than 10% from initial concentration for 24 hours of storage, both in glass bottle and pvc bag. Stability of cisplatin 200 microgram/ml in both container were not different. and Condition of light exposure did not have significant effect on stability of cisplatin 200 microgram/ml in glass bottle. 2) The etoposide 200 microgram/ml was not precipitated and stable for 24 hours, but we could find the precipitates of etoposide with the concentration of 400 microgram/ml or higher for 24 hours.
Cisplatin 200 microgram/ml and etoposide 200 microgram/ml in 0.9% sodium chloride were stable at room temperature under room fluorescent light for 24 hours.
