What classification of Drug Utilization Review (DUR) evaluates a patient's drug therapy before medication is dispensed?

The classification of Drug Utilization Review (DUR) that evaluates a patient's drug therapy before medication is dispensed is prospective DUR. This type of review is conducted prior to the dispensing of a medication and involves assessing various factors, such as potential drug interactions, allergies, and appropriateness of the prescribed therapy based on the patient's history and current medications. The objective is to prevent adverse drug events and ensure the safety and effectiveness of the therapy before the medication reaches the patient.

In contrast, concurrent DUR occurs during the course of therapy, allowing for monitoring and adjustments as a patient is actively taking medications. Retrospective DUR, on the other hand, involves reviewing medication use after the fact, examining records and clinical outcomes to identify patterns or issues that may have occurred during treatment. Introspective is not a standard classification within the context of DUR and does not pertain specifically to the evaluation of drug therapy.
