Summary
Sotalol is a non-selective beta-blocker with class III antiarrhythmic activity, so adding betaxolol duplicates beta-blockade. This increases the risk of severe bradycardia, AV block, and hypotension.
What this interaction means in plain words
Betaxolol and Sotalol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Betaxolol belongs to Cardiovascular; Sotalol belongs to Cardiovascular.
Why it happens
Additive beta-adrenergic blockade on the sinus node, AV node, and vasculature.
What to do
