Quantitative and qualitative control of cytotoxic preparations by HPLC-UV in a centralized parenteral preparations unit.
The constantly growing incidence of cancer and long-term treatment are leading to an increasing number of cytotoxic preparations in hospital pharmacies. Security and quality standards of cytotoxic preparations are essential to assure treatment efficiency and limit iatrogenic toxicity. In order to secure the process of cytotoxic preparations; we decided to install a quantitative and qualitative High Performance Liquid Chromatography (HPLC) control of cytotoxic preparations carried inside our pharmacotechnic unit. A 100 microl sample of each preparation was assayed by HPLC with ultraviolet/visible-diode array detection, which enabled the identification of all cytotoxic agents thanks to their characteristic UV spectra. We developed rapid and specific HPLC assays that determined qualitatively and quantitatively the presence of 21 different cytotoxic agents in less than 3.5 min. A fifteen per cent tolerance from the theoretical concentration was chosen in agreement with preparation and dosage bias, and a first period control of more than 4400 preparations revealed that around 7.7% preparations did not conform. The main objective of these controls was to avoid the administration of defective chemotherapies to patients and finally to use their results to identify error factors; as a result we will take corrective measures in order to reduce error frequency.
