Description
Antihypertensive; Selective Beta-1 Blocker. (Nebivolol) is a highly selective beta-1 adrenergic receptor antagonist drug It has weak beta-2 adrenergic receptor antagonist activity. When d-nebivolol blocks beta-1 adrenergic, then it results in decreased resting heart rate, myocardial contractility, exercise heart rate, systolic blood pressure, and diastolic blood pressure. The selectivity of d-nebivolol limits the magnitude of beta blocker adverse effects in the airways or relating to insulin sensitivity. (Nebivolol) inhibits aldosterone, and antagonizes beta-1 receptors in the juxtaglomerular apparatus and inhibits the renin release. When aldosterone decreases then blood volume also decreases, and decreased renin results in reduced vasoconstriction. l-nebivolol shows beta-3 adrenergic receptor agonist activity that promotes endothelial nitric oxide synthase, enhances nitric oxide levels; resulting in vasodilation, reduced peripheral vascular resistance, increased stroke volume, ejection fraction, and cardiac output. (Nebivolol) benefits heart failure patients by reducing oxidative stress, decreasing platelet volume and aggregation.

Dosage
Dose must be taken according to the doctor’s advice only; doses given below are suggested as supportive literature for better understanding in some areas of requirements.

In patients over 65 years of age, the starting dose is 2.5mg daily, if required then the daily dose may be increased to 5mg. In patients of chronic heart failure, along with the use of other drugs like; diuretics and/or digoxin and/or ACE inhibitors and/or angiotensin II antagonists, the dose of these drugs and nebivolol must be adjusted accordingly, with initial dose of nebivolol as 1.25mg daily to 2.5mg and then to 5mg per day and then 10mg per day at intervals of 1-2 weeks based on patient’s tolerability.

Precautions & Warnings
Exposure to beta-blockers during pregnancy may increase the risk for adverse events in the neonate. Chronic maternal hypertension may increase the risk of birth defects, low birth weight, premature delivery, stillbirth, and neonatal death. Untreated chronic hypertension may also increase the risks of adverse maternal outcomes, including gestational diabetes, preeclampsia, delivery complications, stroke, and myocardial infarction so consult the doctor for proper management and treatment of hypertension during pregnancy. (Nebivolol) may cause harmful effects on pregnancy and may harm fetus/newborn. As a beta-adrenoceptor blockers this drug may reduce placental perfusion, which has been linked with growth retardation, intrauterine death, abortion or early labour.

Food Interactions
Avoid the use of potassium rich diet along with this medicine because, potassium-rich foods when taken along with nebivolol can result in high potassium levels in the blood.
