bisoprolol: Coronary artery disease – dosing, side effects, evidence A – Evigrade
bisoprolol
Selective beta-adrenergic blockers
ATC code: C07AB07(Bisoprolol)
Mechanism of action
Highly selective beta-1 adrenergic receptor blocker. Reduces heart rate, cardiac output, and renin secretion. At therapeutic doses it has negligible effect on beta-2 receptors in bronchi and vasculature. In heart failure it reduces sympathoadrenal neurohormonal activation and improves myocardial remodeling.
Indications
A
Atrial fibrillation
First line
Beta-blockers are first-line rate control agents in atrial fibrillation per 2020. Bisoprolol is given to achieve a target resting HR below 110 bpm (lenient control) or below 80 bpm (strict control when indicated).
Ventricular rate control in atrial fibrillation.
A
Coronary artery disease
First line
Beta-blockers are first-line anti-anginal therapy in stable angina. They reduce heart rate, myocardial oxygen demand, and angina frequency. Target resting heart rate is 55–60 bpm.
A
Heart failure
First line
Bisoprolol is one of three beta-blockers proven to reduce mortality in HFrEF (alongside carvedilol and metoprolol succinate). The CIBIS-II trial showed a 34 % reduction in all-cause mortality. Start at 1.25 mg daily, titrate every 2 weeks to target dose of 10 mg.
HFrEF (LVEF 40 % or below).
B
Hypertension
Individual decision
Beta-blockers as antihypertensive monotherapy in the absence of CAD, HF, tachyarrhythmia, or post-MI status are not first-line per 2024, 2017, and NG136. In younger patients without a compelling indication, ACEi/ARB, CCB, or thiazide-like diuretic is preferred. ESC/ESH 2024 explicitly notes that beta-blockers are less effective at stroke prevention than other classes. Bisoprolol as first-line antihypertensive is justified only in concurrent CAD, HF, AF, or tachyarrhythmia. Dose 5–10 mg once daily.
Practical notes
Timing and administration
Take in the morning, once daily, with or without food. Do not stop abruptly – taper over 1–2 weeks. Sudden withdrawal can trigger rebound tachycardia and angina exacerbation.
Monitoring
Monitor heart rate and BP at each visit. If resting HR drops below 50 bpm or systolic BP below 100 mmHg, reduce dose. In HF patients, transient worsening of symptoms during titration does not warrant discontinuation unless significant hypotension or bradycardia develops.
Second- or third-degree AV block without a pacemaker
Sick sinus syndrome without a pacemaker
Severe bradycardia (HR below 50 bpm before treatment)
Severe bronchial asthma or COPD with significant bronchospasm
Pheochromocytoma without prior alpha-blockade
Cardiogenic shock
Serious adverse effects
AV block
Bronchospasm (rare with selective beta-blockers, but possible)
Masking of hypoglycemia in diabetic patients (tachycardia does not develop)
Common adverse effects
Bradycardia
Hypotension
Fatigue, weakness
Dizziness
Cold extremities
PregnancyFDA C
FDA category C. Beta-blockers can cause fetal growth restriction and neonatal bradycardia. If antihypertensive therapy is needed in pregnancy, labetalol or methyldopa are preferred.
Breastfeeding
Excreted in breast milk. Risk to the infant at standard doses is considered low, but the neonate should be monitored for bradycardia.
