Nebiwin
Nebiwin Uses, Dosage, Side Effects, Food Interaction and all others data.
Nebiwin is a β-adrenergic receptor blocking agent. Nebiwin is a racemate of two enantiomers, d-Nebiwin and l-Nebiwin. Nebiwin exhibits high selectivity for β1-adrenergic receptors and has vasodilating activity due to a direct action on the endothelium, involving nitric oxide release. It lacks intrinsic sympathomimetic and membrane-stabilising activity.
Nebiwin is a selective beta-1 adrenergic receptor antagonist that decreases vascular resistance, increases stroke volume and cardiac output, and does not negatively affect left ventricular function. It has a long duration of action as effects can be seen 48 hours after stopping the medication and a wide therapeutic window as patients generally take 5-40mg daily. Patients should not abruptly stop taking this medication as this may lead to exacerbation of coronary artery disease. Diabetic patients should monitor their blood glucose levels as beta blockers may mask signs of hypoglycemia.

Uses
Nebiwin is used for the treatment of essential hypertension and adjunct in stable mild to moderate heart failure in patients over 70 years.
Nebiwin is also used to associated treatment for these conditions: High Blood Pressure (Hypertension)
How Nebiwin works
Nebiwin is a highly selective beta-1 adrenergic receptor antagonist with weak beta-2 adrenergic receptor antagonist activity. Blocking beta-1 adrenergic receptors by d-nebivolol leads to decreased resting heart rate, exercise heart rate, myocardial contracility, 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. Nebiwin also inhibits aldosterone, and beta-1 antagonism in the juxtaglomerular apparatus also inhibits the release of renin. Decreased aldosterone leads to decreased blood volume, and decreased renin leads to reduced vasoconstriction. l-nebivolol is responsible for beta-3 adrenergic receptor agonist activity that stimulates endothelial nitric oxide synthase, increasing nitric oxide levels; leading to vasodilation, decreased peripheral vascular resistance, increased stroke volume, ejection fraction, and cardiac output. The vasodilation, reduced oxidative stress, and reduced platelet volume and aggregation of nebivolol may lead to benefits in heart failure patients.
Dosage
Nebiwin dosage
Adults: 5 mg daily, maximum recommended dose 40 mg once daily.
Renal Impairment: In patients with severe renal impairment the recommended initial dose is 2.5 mg once daily; titrate up slowly if needed.
Hepatic Impairment: In patients with moderate hepatic impairment, the recommended initial dose is 2.5 mg once daily; titrate up slowly if needed.
Geriatric Patients: It is not necessary to adjust the dose in the elderly.
Pediatric Use: Safety and effectiveness of Nebiwin in pediatric patients have not been established.
Side Effects
The most common side effects are headache, nausea and bradycardia.
Toxicity
Patients experiencing an overdose may present with bradycardia, hypotension, cardiac failure, dizziness, hypoglycemia, fatigue, vomiting, bronchospasm and heart block. Treat overdose with general supportive measures including intravenous atropine for bradycardia, vasopressors and intravenous fluids for hypotension, isoproterenol infusion for heart block, digitalis glycosides and diuretics for congestive heart failure, bronchodilators for bronchospasm, and intravenous glucose for hypoglycemia.
Precaution
Patients with inadequate cardiac function, well-compensated heart failure, myasthenia gravis. Patients undergoing major surgery involving general anaesth. May mask signs and symptoms of hypoglycaemia and hyperthyroidism. Abrupt withdrawal may exacerbate angina symptoms and/or precipitate MI and ventricular arrhythmias in patients with coronary artery disease. Pregnancy and lactation.
Interaction
Use caution when Nebiwin is co-administered with CYP2D6 inhibitors (quinidine, propafenone, fluoxetine, paroxetine, etc.), Do not use Nebiwin with other β-blockers, both digitalis glycosides and β-blockers slow atrioventricular conduction and decrease heart rate. Concomitant use can increase the risk of bradycardia, Nebiwin can exacerbate the effects of myocardial depressants or inhibitors of AV conduction, such as certain calcium antagonists (verapamil and diltiazem), or antiarrhythmic agents, such as disopyramide.
Food Interaction
- Avoid alcohol.
- Take with or without food.
Nebiwin Alcohol interaction
[Moderate]
Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation.
Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.
Caution and close monitoring for development of hypotension is advised during coadministration of these agents.
Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs.
Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.
Nebiwin Cholesterol interaction
[Moderate] Beta-adrenergic receptor blocking agents (aka beta-blockers) may alter serum lipid profiles.
Increases in serum VLDL and LDL cholesterol and triglycerides, as well as decreases in HDL cholesterol, have been reported with some beta-blockers.
Patients with preexisting hyperlipidemia may require closer monitoring during beta-blocker therapy, and adjustments made accordingly in their lipid-lowering regimen.
Nebiwin multivitamins interaction
[Moderate] ADJUST DOSING INTERVAL: Concurrent administration with calcium salts may decrease the oral bioavailability of atenolol and possibly other beta-blockers.
The exact mechanism of interaction is unknown.
In six healthy subjects, calcium 500 mg (as lactate, carbonate, and gluconate) reduced the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of atenolol (100 mg) by 51% and 32%, respectively.
The elimination half-life increased by 44%.
Twelve hours after the combination, beta-blocking activity (as indicated by inhibition of exercise tachycardia) was reduced compared to that with atenolol alone.
However, during a 4-week treatment in six hypertensive patients, there was no difference in blood pressure values between treatments.
The investigators suggest that prolongation of the elimination half-life induced by calcium coadministration may have led to atenolol cumulation during long-term dosing, which compensated for the reduced bioavailability.
It may help to separate the administration times of beta-blockers and calcium products by at least 2 hours.
Patients should be monitored for potentially diminished beta-blocking effects following the addition of calcium therapy.
