Insights

Barnidipine, a calcium channel blocker, effectively lowers blood pressure and reduces oxidative stress markers in hypertensive patients. However, it shows neutral effects on lipid profiles, glucose, and clotting factors, suggesting its primary role as an antihypertensive agent.

Area of Science:

  • Cardiology
  • Pharmacology
  • Metabolic Research

Background:

  • The metabolic effects of barnidipine, a calcium channel blocker, are not fully understood.
  • Essential hypertension management requires evaluation of drug impacts on atherogenesis, oxidative stress, and clotting.

Purpose of the Study:

  • To assess barnidipine's effects on metabolic parameters, oxidative stress, and clotting activity in patients with essential hypertension.
  • To determine if barnidipine influences atherogenic risk factors beyond its blood pressure-lowering effects.

Main Methods:

  • An open-label pilot study involving 40 adult patients with essential hypertension.
  • Patients received barnidipine 10 mg once daily, with assessments of blood pressure, lipid profile, glucose homeostasis, renal function, electrolytes, clotting parameters, and oxidative stress markers (isoprostanes).

Main Results:

  • Barnidipine significantly reduced systolic and diastolic blood pressure and isoprostane levels.
  • No significant changes were observed in lipid profile, apolipoprotein levels, glucose homeostasis, renal function, or electrolyte balance.
  • Clotting/fibrinolytic status and the activity of inflammatory mediators (lipoprotein-associated phospholipase A2, paraoxonase 1) remained unaffected.

Conclusions:

  • Barnidipine is primarily an effective antihypertensive agent with neutral effects on most studied metabolic parameters in hypertensive individuals.
  • Further research is needed to confirm any potential antioxidant effects of barnidipine.

Antihypertensive Drugs: Action of Diuretics

Diuretics are antihypertensive drugs used to treat hypertension resulting from sodium and water retention. Sodium, vital for fluid balance and nerve or muscle function, is regulated by the kidneys through millions of nephrons. Blood enters nephrons via afferent arterioles, which branch into capillaries called glomeruli. These filter blood plasma, allowing water and solutes, like sodium ions, to pass through capillary walls into Bowman's capsule. The filtrate then flows through various tubules...

Antihypertensive Drugs: Action of β1 Blockers

β1-receptors are primarily located in the heart and kidneys. In cardiac myocytes, these receptors interact with neurotransmitters released by the sympathetic nervous system during heightened activity or danger. As a result, β1-receptors get activated, initiating a series of biochemical processes. Excessive activation of beta receptors due to chronic stress can abnormally increase heart rate and contractility, resulting in high blood pressure or hypertension. To counteract this, β1-blockers...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Antihypertensive Drugs: Types of β-Blockers

β receptors are classified into three subclasses: β1, β2, and β3. β1 receptors are primarily located in the heart and kidneys. When they get activated, they increase heart rate, contractility, and renin release. This process enhances blood pressure and aids in stress management. In contrast, β2 receptors are situated mainly in the lungs, blood vessels, and skeletal muscles. Upon activation, they trigger smooth muscle relaxation, causing bronchodilation and vasodilation. This widens airways and...

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...
Blood Pressure01:30

Blood Pressure

Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
