'No-Frills Prils': GPs' views on drug costs and therapeutic interchange of angiotensin-converting enzyme inhibitors: a qualitative study

Abstract

Medications form a significant portion of spending in primary health care. Angiotensin-converting enzyme inhibitors (ACE-Is) are among the most prescribed blood pressure medications in general practice. Medications within this class are considered therapeutically equivalent, but the cost of each ACE-I varies. Our aim was to explore cost and other factors that influence general practitioners (GPs) to prescribe a specific ACE-I and understand their views on therapeutic interchange within this drug class. We conducted a qualitative study of Australian GPs using thematic analysis. We found that GPs were aware of therapeutic equivalency within the ACE-I class, but unaware of the cost differences...
