Renin–angiotensin system
Renin–angiotensin system - brief summary
The renin–angiotensin system (RAS), or renin–angiotensin–aldosterone system (RAAS), is a hormone system that regulates blood pressure and fluid and electrolyte balance, as well as systemic vascular resistance. If the RAS is abnormally active, blood pressure will be too high. There are several types of drugs which includes ACE inhibitors, ARBs, and renin inhibitors that interrupt different steps in this system to improve blood pressure. These drugs are one of the primary ways to control high blood pressure, heart failure, kidney failure, and harmful effects of diabetes.
