Olmesartan in Management of Proteinuria

Abstract

Proteinuria is a marker and predictor of cardiovascular morbidity and mortality. Blockade of angiotensin receptor might result in reduction in proteinuria. Olmesartan, an Angiotensin Receptor Blocker (ARB) which is approved for the treatment of hypertension is believed to produce antiproteinuric effects through different mechanisms. The objective of this review is to assess the cause, duration and degree of proteinuria and understand the current place of olmesartan in management of proteinuria associated with Cardiovascular Disease(CVD) and hypertension. We performed a comprehensive search of MEDLINE, PubMed and Google Scholar databases for articles related to Olmesartan and proteinuria (till June 2017). Angiotensin-II induces transforming growth factor-β upregulation and increase transcapillary pressure. AT-I receptor blocked by olmesartan result in reduction in proteinuria. Olmesartan significantly reduces Blood Pressure (BP) and delays the onset of Chronic Kidney Disease (CKD), it also delayed the risk of onset of microalbuminuria. Olmesartan have nephroprotective, antioxidant, antifibrotic activities and proteinuria reducing effects which can be beneficial in patients with hypertension. Olmesartanis believed to produce antiproteinuric effects through different mechanisms. It is indicated for treatment of hypertension to reduce the risk of fatal and non fatal CV events which may or may not be associated with proteinuria.
