Insights

Darusentan, a novel endothelin receptor blocker, effectively controlled blood pressure in over 50% of patients with resistant hypertension. However, its use was linked to significant peripheral edema and fluid retention, warranting further long-term safety evaluation.

Area of Science:

  • Cardiovascular Medicine
  • Pharmacology

Background:

  • Resistant hypertension poses a significant challenge in antihypertensive drug treatment.
  • The DORADO trial investigated darusentan, a selective endothelin receptor blocker, for patients with uncontrolled hypertension despite multiple medications.

Discussion:

  • Darusentan demonstrated efficacy in lowering both clinical and ambulatory blood pressure in over 50% of participants.
  • A notable concern is the high incidence of peripheral edema and fluid retention associated with darusentan, impacting its safety and tolerability profile.

Key Insights:

  • Selective endothelin receptor blockade with darusentan shows promise for treating resistant hypertension.
  • Peripheral edema and fluid retention are significant side effects requiring careful consideration.

Outlook:

  • Further long-term studies are essential to fully assess the safety and efficacy of darusentan.
  • The potential benefits of darusentan must be weighed against its side effect profile in clinical practice.

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme (ECE). Of...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...
Antihypertensive Drugs: Angiotensin II Receptor Blockers01:30

Antihypertensive Drugs: Angiotensin II Receptor Blockers

In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...

Antihypertensive Drugs: Direct Renin Inhibitors

The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...

Antihypertensive Drugs: Vasodilators

Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...
