How do ACE inhibitors worsen renal function?

During ACEI initiation, renal dysfunction can occur due to a drop in renal perfusion pressure and subsequent decrease in glomerular filtration. This is attributed to the drug’s preferential vasodilation of the renal efferent arteriole, which impairs the kidney’s ability to compensate for low perfusion states.

Why are ACE inhibitors not OK for kidney patients?

In conditions in which glomerular filtration is critically dependent on angiotensin II-mediated efferent vascular tone (such as a post-stenotic kidney, or patients with heart failure and severe depletion of circulating volume), ACE inhibition can induce acute renal failure, which is reversible after withdrawal of the …

How do angiotensin converting enzyme ACE inhibitors slow the progression of chronic kidney disease CKD )?

In contrast to some other antihypertensive drugs, angiotensin-converting enzyme (ACE) inhibitors lower glomerular capillary pressure, decrease proteinuria, and may halt progressive glomerular injury and loss of renal function in experimental chronic renal failure (CRF).

How do ACE inhibitors delay progression of diabetic nephropathy?

This suggests that ACE inhibitors cause an increase in the serum creatinine levels while ARBs stabilize the same thus, improving the renal function and delaying the progression of diabetic nephropathy.

What is the role of angiotensin converting enzyme inhibitors?

Abstract Chronic kidney disease (CKD) is a global health problem associated with considerable morbidity and mortality and despite advances in the treatment of end stage renal disease (ESRD) mechanisms to prevent and delay its progression are still being sought.

What is the role of the renin angiotensin aldosterone system?

The renin-angiotensin-aldosterone system (RAAS) plays a pivotal role in many of the pathophysiologic changes that lead to progression of renal disease. Traditionally RAAS was considered as an endocrine system and its principal role was to maintain blood pressure (BP).

How much antihypertensive effect does ACE inhibitor have?

In meta-analysis of existing combination studies, there was general agreement that the amount of additional antihypertensive effect was approximately 5 mmHg and often less when maximal dosages of the ACE inhibitor were used before the addition of the ARB15.

What is the progression of renal disease characterized by?

Regardless of the primary entity, progression of renal disease is characterized by pathomorphologic changes that comprise early renal inflammation, followed by subsequent tubulointerstitial fibrosis, tubular atrophy, and glomerulosclerosis4.
