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.
Abstract:
The effect of barnidipine, a calcium channel blocker, on metabolic parameters is not well known. The authors conducted the present pilot study to evaluate the possible effects of barnidipine on parameters involved in atherogenesis, oxidative stress, and clotting activity. This open-label intervention study included 40 adult patients with essential hypertension who received barnidipine 10 mg once daily. Barnidipine significantly reduced systolic and diastolic blood pressure as well as isoprostane levels, which represent a reliable marker of oxidative stress. In contrast, barnidipine had a neutral effect on lipid profile and apolipoprotein levels, did not influence glucose homeostasis, had no effect on renal function, and did not cause any changes in electrolyte levels. Moreover, barnidipine did not affect either the clotting/fibrinolytic status (evaluated by measurement of fibrinogen, total plasminogen activator inhibitor, tissue plasminogen activator, and a2 antiplasmin) or the enzymatic activity of the inflammatory/anti-inflammatory mediators lipoprotein-associated phospholipase A2 and paraoxonase 1, respectively. Barnidipine should be mainly considered as an antihypertensive agent with neutral effects on most of the studied metabolic parameters in hypertensive patients. Any antioxidant effect of barnidipine needs further investigation.

Blood Pressure
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...
