What is the primary purpose of a drug utilization review (DUR)?

The primary purpose of a drug utilization review (DUR) is to ensure the appropriateness of drug therapy. DUR processes are critical components of pharmacy practice and healthcare systems because they analyze prescribed medications to assess whether they are being used correctly and effectively according to established guidelines. This includes evaluating factors such as the indication for therapy, potential drug interactions, adherence to prescription guidelines, and safety for patients.

By focusing on the appropriateness of drug therapy, DUR helps in identifying potential medication errors, preventing adverse drug reactions, and promoting optimal therapeutic outcomes. Healthcare providers utilize DUR as a tool to improve patient safety and the quality of care, thereby ensuring that patients receive the most effective and necessary medications for their conditions.

The other options, while related to aspects of healthcare and pharmaceuticals, do not align with the primary goals of DUR. For example, enhancing the marketing of pharmaceuticals is not a focus of DUR, as it centers on clinical safety and efficacy rather than commercial interests. Similarly, determining drug pricing and validating health insurance claims are administrative and financial processes, rather than directly addressing the medical appropriateness of drug therapy. This distinction highlights the essential role of DUR in promoting safe and effective medication use among patients.
