Why ARB and ACEI don't combine together..???
I don't known why ARB and ACEIs not given together but there combination are more effective than given alone.
Combination is high risk for renal dysfunction and vascular abnormalities.
Avoid prescribing an angiotensin-converting enzyme (ACE) inhibitor and an angiotensin receptor blocker (ARB) for patients at high risk of vascular events or renal dysfunction. The combination does not reduce poor outcomes, and leads to more adverse drug-related events than an ACE inhibitor or ARB alone.
