Beta1-adrenergic agonists, also known as Beta1-adrenergic receptor agonists, are a class of drugs that bind selectively to the beta-1 adrenergic receptor. As a result, they act more selectively upon the heart. Beta-adrenoceptors typically bind to norepinephrine release by sympathetic adrenergic nerves and to circulating epinephrine. The effect of B-adrenoceptors is cardiac stimulation, such as increased heart rate, heart contractility, heart conduction velocity and heart relaxation.[1]
Examples
Examples include:
- denopamine[2][3] β1 agonist
- dobutamine β1>β2 agonist
- xamoterol β1 partial agonist
- epinephrine
- Epinephrine is a non-selective beta agonist, this means it also stimulates the beta 2 adrenergic receptor. Therefore, epinephrine is a Beta2-adrenergic agonist.
- Isoprenaline
