WebJul 24, 2016 · Variability in receptor specificity among the adrenergic agonists can be illustrated with three drugs: albuterol, isoproterenol, and epinephrine. Albuterol is highly selective, acting at beta 2 receptors only. Isoproterenol is less selective, acting at beta 1 receptors and beta 2 receptors. WebSome alpha-blockers will target only certain alpha-receptors. This characteristic is “selectivity,” and it is a part of the decision process when choosing an alpha-blocker to …
WebApr 12, 2024 · Our results show that two non-selective adrenergic agonists, E and NE, and a selective β-AR agonist, ISO, commonly increased the migration of MDA-MB-231 cells and Hep3B cells. However, such an increase was significantly abrogated by EPF treatment (Figure 5A–F). As Hep3B cells were treated with relatively higher concentrations (25–100 … WebThe medicines used as cardiovascular agents are alpha1-selective antagonists. Alpha1-selective antagonists block the alpha adrenoreceptors on the vascular smooth muscle and widen the arteries, causing vasodilatation and a drop in blood pressure. These agents are used to treat hypertension.
