Insights

Valsartan more effectively lowers blood pressure (BP) in elderly patients with hypertension than enalapril. Unlike enalapril, valsartan also significantly improved memory functions.

Area of Science:

  • Cardiology
  • Geriatrics
  • Pharmacology

Background:

  • Essential hypertension is a prevalent condition in elderly individuals, increasing the risk of cardiovascular and cognitive decline.
  • Angiotensin II (Ang II) AT1 receptor antagonists and ACE inhibitors are common antihypertensive drug classes with distinct mechanisms of action.
  • The impact of these medications on cognitive function in older adults warrants further investigation.

Purpose of the Study:

  • To compare the efficacy of valsartan (Ang II AT1 receptor antagonist) versus enalapril (ACE inhibitor) in managing blood pressure (BP) in elderly hypertensive patients.
  • To assess the effects of valsartan and enalapril on cognitive functions in this patient population.

Main Methods:

  • A prospective, randomized, open-label, blinded-endpoint study involving 144 elderly hypertensive patients (aged 61-80 years).
  • Patients received either valsartan 160 mg once daily or enalapril 20 mg once daily for 16 weeks.
  • Blood pressure was measured regularly, and cognitive function was evaluated using five standardized tests at baseline and after 16 weeks.

Main Results:

  • Both valsartan and enalapril demonstrated significant antihypertensive effects.
  • Valsartan achieved a statistically greater reduction in systolic and diastolic blood pressure compared to enalapril (P<0.01).
  • Valsartan significantly improved word list memory and recall scores (+11.8% and +18.7%, respectively; P<0.05), while enalapril did not significantly alter cognitive test scores.

Conclusions:

  • Valsartan (160 mg once daily) is more effective than enalapril (20 mg once daily) in reducing blood pressure in elderly hypertensive patients.
  • Valsartan treatment, unlike enalapril, showed significant improvements in specific cognitive functions, particularly episodic memory.
  • These findings suggest potential benefits of valsartan beyond BP control in older adults with hypertension.

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...

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

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,...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
