Generic Bystolic Information

Introduction

Bystolic (nebivolol) is a β‑blocker indicated for the long‑term management of hypertension. In Hong Kong, high blood pressure remains a leading modifiable risk factor for cardiovascular disease, affecting an estimated 20 % of adults aged ≥ 35 years (Hong Kong Department of Health, 2022). By lowering arterial pressure, Bystolic reduces the risk of stroke, myocardial infarction, and heart failure. It is manufactured by multiple pharmaceutical companies and is classified within the blood‑pressure medication group. In addition to hypertension, clinicians may prescribe nebivolol for certain cases of chronic heart failure, although this indication is not universally approved across all jurisdictions.

What is Bystolic?

Bystolic is a tablet formulation that contains the active compound nebivolol, a third‑generation selective β₁‑adrenergic receptor blocker with additional nitric‑oxide–mediated vasodilatory properties. The drug was originally developed by GSK and received U.S. FDA approval in 2007. Since then, generic versions have been produced by several licensed manufacturers worldwide. Bystolic is marketed under the same name in many regions, while other brand names for nebivolol include Nebivol, Nebilet, and Nebivolol‑Rex.

Our online pharmacy supplies the generic nebivolol tablets that are pharmacologically identical to the branded Bystolic, providing a cost‑effective option for patients in Hong Kong.

How Bystolic Works

Nebivolol binds selectively to β₁‑adrenergic receptors on cardiac myocytes, blocking the effects of endogenous catecholamines such as norepinephrine. This results in:

• Reduced heart rate – slower pacing decreases myocardial oxygen demand.
• Decreased contractile force – lower stroke volume contributes to reduced cardiac output.

In parallel, nebivolol stimulates endothelial nitric‑oxide synthase (eNOS), enhancing nitric‑oxide (NO) production. NO induces smooth‑muscle relaxation in arterial walls, producing vasodilation that further lowers systemic vascular resistance. The combined β₁‑blockade and NO‑mediated vasodilation yield a rapid onset of blood‑pressure reduction (typically within 2 hours) and a half‑life of approximately 12 hours, supporting once‑daily dosing.

Conditions Treated with Bystolic

• Essential (primary) hypertension – the primary FDA‑approved indication; supported by multiple randomized controlled trials showing significant systolic and diastolic reductions.
• Stage 1–2 hypertension (as defined by the Hong Kong Clinical Practice Guidelines for Hypertension, 2021) – nebivolol is recommended as a first‑line agent, particularly when a patient benefits from β‑blockade and vasodilation.
• Mild to moderate chronic heart failure (NYHA Class II–III) – nebivolol has demonstrated mortality benefit in the SENIORS trial; however, local approval for this use varies, and prescribing is at the physician’s discretion.

In Hong Kong, hypertension prevalence and the consequent burden of cardiovascular morbidity make Bystolic a valuable component of population‑level risk‑reduction strategies.

Patient Groups Most Likely to Benefit

• Adults with newly diagnosed hypertension who have a resting heart rate ≥ 70 bpm, where β‑blockade can assist rate control.
• Patients with hypertension and concomitant metabolic syndrome – nebivolol’s neutral effect on glucose metabolism makes it preferable to non‑vasodilating β‑blockers.
• Elderly patients (≥ 65 years) – the drug’s once‑daily dosing and favorable side‑effect profile (e.g., lower incidence of fatigue compared with older β‑blockers) support adherence.
• Individuals intolerant of diuretics or ACE inhibitors due to electrolyte disturbances or cough, respectively.

Contra‑indications / caution include severe bradycardia (heart rate < 50 bpm), second‑ or third‑degree atrioventricular block without a pacemaker, decompensated heart failure, and untreated pheochromocytoma. Nebivolol should be used with caution in patients with severe hepatic impairment because clearance is reduced.

Risks, Side Effects, and Interactions

Common

• Headache – often mild and transient.
• Dizziness or light‑headedness – related to orthostatic hypotension, particularly after the first dose.
• Fatigue – generally improves with continued therapy.
• Nasal congestion – occasional nasal stuffiness.

Rare

• Bradycardia – heart rate < 50 bpm; may require dose reduction.
• Cold extremities – peripheral vasoconstriction in some patients.
• Sleep disturbances – insomnia or vivid dreams reported infrequently.

Serious

• Severe hypotension – marked drop in blood pressure leading to syncope; urgent medical assessment required.
• Acute heart failure decompensation – rare but possible if the drug is abruptly withdrawn.
• Bronchospasm – although nebivolol is β₁‑selective, patients with severe asthma or chronic obstructive pulmonary disease should be monitored closely.

Clinically Relevant Drug–Drug Interactions

• Other antihypertensives (e.g., ACE inhibitors, calcium channel blockers) – additive blood‑pressure lowering; monitor for excessive hypotension.
• Drugs affecting hepatic CYP2D6 (e.g., fluoxetine, paroxetine, quinidine) – can increase nebivolol plasma levels; dose adjustment may be needed.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – may blunt antihypertensive effect.
• Insulin or oral hypoglycemic agents – nebivolol does not significantly alter glucose control, but routine monitoring remains prudent.

Patients should disclose all prescription, over‑the‑counter, and herbal products to their healthcare provider before initiating Bystolic.

Practical Use: Dosing, Missed Dose, Overdose

• Starting dose – 5 mg once daily for most adults; clinicians may begin at 2.5 mg in elderly or renally impaired patients.
• Maintenance dose – titrated to 5 mg or 10 mg once daily based on blood‑pressure response and tolerability. The maximum recommended dose is 20 mg daily.
• Administration – tablets may be taken with or without food; consistent timing each day improves steady‑state levels.
• Missed dose – if a dose is realized within 12 hours of the scheduled time, take it immediately. If later, skip the missed dose and resume the regular schedule; do not double‑dose.
• Overdose – signs may include profound bradycardia, hypotension, and syncope. Immediate medical attention is required; treatment is supportive, focusing on cardiovascular monitoring and, if needed, intravenous atropine or glucagon.

Patients with liver disease, severe renal impairment (eGFR < 30 mL/min/1.73 m²), or those on interacting medications should have dosing individualized by a physician.
