Summary
Rivastigmine increases vagal tone, and atenolol slows sinoatrial and AV nodal conduction, so the two together can cause marked bradycardia, heart block, and syncope. Older and frail patients with dementia are at particular risk of falls and injury.
What this interaction means in plain words
Atenolol and Rivastigmine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Atenolol belongs to Cardiovascular; Rivastigmine belongs to Central Nervous System.
Why it happens
Additive negative chronotropic effects: cholinesterase inhibition enhances parasympathetic activity while beta-blockade reduces sympathetic drive.
What to do
If combined, monitor heart rate, ECG and symptoms such as dizziness or syncope, especially when starting or increasing either drug. Reduce the dose or switch to an alternative if symptomatic bradycardia occurs.
