Vasopressin Antagonists in Physiology and Disease

1 Introduction Hyponatremia is the most common electrolyte abnormality in hospitalized patients occurring in as many as 15%–30% of patients. It can present acutely or chronically. The treatment of hyponatremia has been reviewed elsewhere extensively but includes simple strategies such…

Molecular Biology and Gene Regulation

1 Introduction Vasopressin, or in humans and rodents, arginine vasopressin (AVP), is the most important hormone in the regulation of urine concentration. Without the ability to concentrate our urine, we would excrete as much as 170–180 L of urine per…

Vasopressin in the Kidney—Historical Aspects

1 Introduction A century ago it was well established that the infusion of pituitary extract into animals could cause antidiuresis and a concentrated urine. The structure of this neurohypophyseal hormone, mammalian vasopressin (AVP) or antidiuretic hormone (ADH) was discovered in…

Renin–Angiotensin Blockade: Therapeutic Agents

Key Points The renin–angiotensin system (RAS) has emerged over the last several decades as a key mediator of hypertension as well as cardiorenal homeostasis and disease progression. Several drug classes including angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), and…

The Renin–Angiotensin System and the Heart

1 Introduction For many years, the renin–angiotensin system (RAS) was thought to be mainly a traditional circulating hormonal system whereby renal renin-dependent production of angiotensin II (Ang II) occurred in response to a fall in macula densa sodium concentration, low…

The Renin–Angiotensin–Aldosterone System and the Kidney

1 Introduction The relationship between the renin–angiotensin–aldosterone system (RAAS) and its modulation of kidney function has been present for almost a century. It dates back to when renin was first described in the late 1800s and integrated into renal physiology…
