Moderate

Amlodipine × Propranolol

Calcium channel blockers (dihydropyridines)×Non-selective beta blocker

Mechanism

Additive bradycardia and hypotension. Propranolol is non-selective (blocks β1 and β2); risk is higher than with bisoprolol – bronchospasm possible in asthma.

Symptoms

Lower blood pressure, postural dizziness, fatigue. Older patients: fall risk.

Management

The combination is acceptable in ischaemic heart disease. In asthma or COPD, a selective beta-blocker (bisoprolol, metoprolol) is preferable. Check pulse and blood pressure 1–2 weeks after start.
