Beta1-adrenergic agonist

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.

Examples
Examples include:


 * denopamine  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
