Drug Utilization Patterns and Potential Drug–Drug Interaction Burden in Respiratory Prescriptions: A Real-World Community Pharmacy Study

Background

Respiratory disorders are frequently managed in community pharmacies and may involve complex multidrug regimens, particularly in asthma and chronic obstructive pulmonary disease (COPD). We aimed to characterize respiratory pharmacotherapy and moderate or major potential drug–drug interaction (DDI) risk using one index respiratory prescription per patient.
