Which statement about DUR is accurate?

• A. Prospective DUR is performed only at pharmacy audits
• B. Retrospective DUR occurs at dispensing time
• C. DUR is not used in clinical practice
• D. Prospective DUR is performed at the time of dispensing

Answer: (D)

Drug Utilization Review (DUR) aims to ensure medications are used safely and effectively. It has two forms: prospective and retrospective. Prospective DUR is performed at the time of dispensing—pharmacists review the prescription during the dispensing process to catch issues like drug–drug interactions, improper dosing, duplications, or contraindications and intervene before the patient receives the medication. That makes it the right choice, since it occurs at the moment of dispensing. Retrospective DUR looks back at past prescribing and dispensing data after the fact to identify patterns and areas for improvement, not at the point of dispensing. The other statements are inaccurate because DUR is indeed used in clinical practice, and prospective DUR is not limited to audits nor performed after dispensing.
