Chống chỉ định
Acute heart failure, cardiogenic shock or episodes of heart failure decompensation requiring IV inotropic therapy; sick sinus syndrome (including sinoatrial block), 2nd- or 3rd-degree heart block (without a pacemaker); history of bronchospasm and bronchial asthma; untreated phaeochromocytoma; severe bradycardia, hypotension (systolic blood pressure of <90 mmHg), severe peripheral circulatory disturbances; metabolic acidosis. Hepatic impairment.
Thận trọng
Patient with peripheral circulatory disorders (e.g. Raynaud's disease, intermittent claudication), 1st-degree heart block, Prinzmetal's angina, diabetes mellitus, thyroid disease, history of psoriasis, COPD, history of severe anaphylaxis to a variety of allergens; myasthenia gravis. Patients undergoing surgery. Avoid abrupt withdrawal; chronic therapy must not be routinely withdrawn before major surgery. May mask the signs and symptoms of hypoglycaemia and hyperthyroidism (particularly tachycardia). Renal impairment; not recommended in severe renal impairment when used for chronic heart failure. Elderly. Pregnancy and lactation.

Significant: Bradycardia. Cardiac disorders: Heart failure, slowed atrioventricular conduction, atrioventricular block. Eye disorders: Impaired vision.

Quá liều
Symptoms: Bradycardia, hypotension, bronchospasm, acute cardiac insufficiency, dizziness, hypoglycaemia, vomiting, and fatigue. Management: Symptomatic and supportive treatment. Administer IV atropine for bradycardia; if insufficient response, give isoprenaline or another agent with positive chronotropic properties cautiously. Administer IV fluids and vasopressors for hypotension; IV glucagon may also be useful. For 2nd- or 3rd-degree heart block, monitor the patient and administer isoprenaline infusion. Give digitalis glycoside and diuretics for CHF; may consider inotropic and vasodilating agents in some cases. Administer bronchodilator therapy (e.g. short-acting inhaled β2-agonist and/or aminophylline) for bronchospasm. Administer IV glucose for hypoglycaemia.

Effect on atrioventricular conduction time may be potentiated and the negative inotropic effect increased with class I (e.g. quinidine, flecainide, lidocaine, disopyramide, mexiletine, propafenone, hydroquinidine, cibenzoline) and class III (e.g amiodarone) antiarrhythmics. May cause profound hypotension and atrioventricular block with IV verapamil . Concomitant use with Ca channel antagonists of verapamil or diltiazem type may have a negative influence on contractility and atrioventricular conduction. May worsen heart failure with centrally acting antihypertensives (e.g. clonidine, methyldopa, guanfacine, moxonidine, rilmenidine). May attenuate reflex tachycardia and increase the risk of hypotension with anaesthetics. May enhance the hypoglycaemic effects of antidiabetic agents. May increase atrioventricular conduction time with digitalis glycosides. Increase risks of hypotension with dihydropyridine Ca antagonists (e.g. amlodipine, nifedipine), amifostine, baclofen, TCAs, barbiturates, and phenothiazines. Increased plasma concentration associated with an increased risk of excessive bradycardia and adverse events with CYP2D6 inhibitors (e.g. fluoxetine, paroxetine, thioridazine, quinidine). Increased plasma concentration with cimetidine. May produce an excessive reduction of sympathetic activity with catecholamine-depleting drugs (e.g. reserpine, guanethidine).

Description: Mechanism of Action: Nebivolol exhibits high selectivity for β1-adrenergic receptors. The possible factors that may be involved in its mechanism of action are decreased heart rate, myocardial contractility, or sympathetic outflow from the CNS, inhibition of renin activity, and decreased peripheral vascular resistance. Additionally, it produces an endothelium-derived nitric oxide-dependent vasodilation which leads to the reduction of systemic vascular resistance. Pharmacokinetics: Absorption: Rapidly absorbed. Bioavailability: Approx 12% (extensive metabolisers); 96% (poor metabolisers). Time to peak plasma concentration: 1.5-4 hours. Distribution: Volume of distribution: 8-12 L/kg. Plasma protein binding: Approx 98%, mainly to albumin. Metabolism: Extensively metabolised in the liver via direct glucuronidation of the parent drug, and to a lesser extent via N-dealkylation, and oxidation by CYP2D6 isoenzyme. Undergoes extensive first-pass metabolism. Excretion: Via urine (extensive metabolisers: 38%; poor metabolisers: 67%; <0.5% as unchanged drug); faeces (extensive metabolisers: 44%; poor metabolisers: 13%; <0.5% as unchanged drug). Elimination half-life: 12 hours (extensive metabolisers); 19 hours (poor metabolisers).
