Which of the Following Drugs is Sympathomimetic

Question

Which of the following drugs is sympathomimetic?
A) Beta1-adrenergic blocker
B) Muscarinic agonist
C) Vagolytic
D) Beta1-adrenergic agonist

Accepted Answer

Beta1-adrenergic agonists are sympathomimetic drugs that activate the sympathetic nervous system by mimicking the actions of endogenous catecholamines such as epinephrine and norepinephrine. They bind to and activate beta1-adrenergic receptors causing an increase in heart rate, cardiac contractility, and cardiac output.
