The stability of carboplatin in ambulatory continuous infusion regimes.
Several anti-cancer agents are administered by continuous infusion in an attempt to improve the therapeutic index obtained with solid tumours. In Exeter this approach, combined with the use of ambulatory infusion pumps, forms the basis of a home oncology programme in which a complete course of medication in pre-filled syringes is supplied on an out-patient basis. It is essential to ensure that the drug remains stable during storage prior to use and also during infusion where the temperature of the drug solution in a holster-worn ambulatory pump can reach 37 degrees C. In this study the stability of a carboplatin infusion (20 mg in 2 ml) in pre-filled syringes under storage and in-use conditions was determined using a stability-indicating HPLC assay. There was no loss of carboplatin from pre-filled syringes stored at 4 degrees C for 5 days. At 37 degrees C, the loss of carboplatin was 3.1% over 24 h.
