This guide summarizes evidence comparing the effectiveness and safety of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor antagonists (ARBs) when used for adults with essential hypertension. The evidence is derived from research studies comparing an ACEI with an ARB.
This guide does not review studies comparing individual drugs within each class or evidence about using ACEIs and ARBs for congestive heart failure or diabetic kidney disease.
