Isoproterenol (Isuprel) is a non-selective beta-adrenergic agonist, meaning it stimulates both beta1 and beta2 receptors. Beta1 receptors are primarily found in the heart, leading to increased heart rate and contractility. Beta2 receptors are located in the smooth muscles of the lungs, vasculature, and skeletal muscle, leading to bronchodilation, vasodilation, and increased muscle and liver glycogenolysis. Isoproterenol does not significantly stimulate alpha1, alpha2, or beta3 receptors.
