02. ACE Inhibitor Conversion Table Resident Editor: Carine Davila, MD Faculty Editor: Elisabeth Askin, MD There are few studies comparing equivalent doses of ACE-inhibitors, for specific indications. Therefore, the above recommendations are based on clinical experiences and are not specific for any indication. Generic forms of ACE Inhibitors (benazepril, captopril, enalapril, fosinopril, and lisinopril) may be purchased at a lower price. There are no “generics” for Accupril, Altace Mavik, and of Univasc. 537 Supplemental Table 1. Doses of ACE-inhibitors and ARBs equivalent to 10mg of Lisinopril ch ACE Inhibitor Switching & Dose Conversion Guide ACE inhibitors are largely interchangeable within the class. This guide covers dose equivalency, key pharmacologic differences, and practical tips for switching between ACE inhibitors. Dose Equivalency Guide Approximate equivalent doses within ACE Inhibitors. Source: Standard pharmacology. This document provides guidance on switching patients between different ace-inhibitor medications, listing considered equivalent starting doses of enalapril, quinapril, and ramipril for patients previously taking other ace-inhibitors such as captopril, fosinopril, lisinopril, perindopril, or trandolapril. ACE-Inhibitors Benazepril (Lotensin) Captopril (Capoten) Enalapril (Vasotec) Fosinopril (Monopril) 10 mg daily 6.25-25 mg three times per day While lisinopril is the most commonly used agent that I see in practice, I thought it would be helpful to put together an ACE Inhibitor Comparison table to share with the audience and highlight some important differences. Ace-inhibitor conversions for all of the common ace-inhibitors based on the estimated potency.
