Does intravenous esmolol reduce blood pressure more than metoprolol and propranolol at comparable degrees of beta-blockade?
Esmolol produces a greater acute reduction in blood pressure compared to other beta-blockers at equivalent levels of beta-blockade, suggesting an additional mechanism of action beyond simple beta-receptor antagonism.
Deegan et al. (1994) studied this question.
