Aim: To identify cancer drugs amenable to strategies for reducing expenditure and avoiding drug wastage.
Methods: Information was sourced from product information in 20 countries on parenteral cytotoxic agents, and cancer and noncancer monoclonal antibodies. Data were collected on vial sizes, overage, stability and presentation forms.
Results: Vial size availability varied significantly between countries, with often only single vial sizes for numerous medications. Overage was poorly reported. Stability data were inconsistent and variable between countries, with most drugs only having a 24 h expiry. Three cancer-indicated monoclonal antibodies, thought suitable for prefilled syringe administration, were only available as vials.
Conclusion: Many expensive cancer drugs are suitable for global cost-reduction strategies. Collaboration is vital to affecting change and reducing expenditure.
