Adrenergic Agonists

Drug Drug Description
Methoxamine An alpha adrenergic agonist used to treat hypotension.
Orciprenaline A beta-2 adrenergic agonist used to treat bronchospasm, asthma, and COPD.
Dobutamine A beta-1 agonist used to treat cardiac decompensation in patients with organic heart disease or from cardiac surgery.

What are Beta-2 agonists examples?

Examples of these short-acting medications include: albuterol (AccuNeb, Proventil HFA, ProAir HFA, Ventolin HFA) and levalbuterol (Xopenex, Xopenex HFA). Long-acting beta-agonists (LABAs) are taken on a daily basis to relax the muscles lining the airways that carry air to the lungs.

Is epinephrine Alpha or Beta?

Epinephrine is a mixed beta1 and beta2 agonist at low doses and an alpha agonist at higher doses. Thus it functions as combined inotrope and chronotrope, and at higher doses as a vasoconstrictor.

What do beta-1 agonists do?

Targeted activation of the beta-1 receptor in the heart increases sinoatrial (SA) nodal, atrioventricular (AV) nodal, and ventricular muscular firing, thus increasing heart rate and contractility. With these two increased values, the stroke volume and cardiac output will also increase.

What do beta-2 adrenergic agonists do?

Beta-2 agonists are drugs that selectively mimic the actions of the endogenous catecholamines epinephrine and norepinephrine. As pharmaceuticals, their major role is to reduce signs and symptoms of asthma and chronic obstructive pulmonary disease by bronchodilation, allowing the patient to breathe more easily.

What are Beta 2 agonists?

Beta2-agonists (bronchodilators) are a group of drugs prescribed to treat asthma. Short-acting beta-agonists (SABAs) provide quick relief of asthma symptoms. They can also be prescribed to be taken before exercising in order to prevent exercise-induced bronchoconstriction.

Is adrenaline a beta agonist?

Epinephrine (adrenaline) is an endogenous catecholamine with potent α- and β-adrenergic stimulating properties. The α-adrenergic action increases systemic and pulmonary vascular resistance, increasing both systolic and diastolic blood pressure.
