Overview
Additive antihypertensive effects may lead to symptomatic hypotension (dizziness, syncope), particularly with initiation, dose increases, or volume depletion.
Mechanism of action
Pharmacodynamic: RAAS blockade plus beta-1 antagonism produces additive reductions in blood pressure and may lower cardiac output.
Clinical management
Start low and titrate; monitor blood pressure and heart rate; assess for orthostasis; adjust doses if symptomatic hypotension or bradycardia occurs; ensure adequate volume status.
