Vasoconstriction Pseudoephedrine is an example of an: A. Beta 2 receptor agonist B. Beta 1 receptor agonist C. Alpha 1 receptor agonist D. Alpha 2 receptor agonist️️C. Alpha 1 receptor agonist Alpha 2 receptor agonists, like Clonidine, are commonly used as stimulants. A. True B. False️️B. False Stimulation of B1 receptors primarily affects the heart by-------------------- heart rate and contractility.️️Increasing heart rate and contractility Stimulation of Beta 2 receptors causes -------------------------- in smooth muscle in the lungs, GI, uterus and liver.️️Relaxation Tamsulosin is an example of a _________________________antagonist and is primarily used to relax smooth muscle in the bladder. A. Beta 1 B. Alpha 2 C. Beta 2 D. Alpha 1️️D. Alpha 1 a. ---------beta blockers inhibit Beta 1 receptors and affect the heart only. b. -----------beta blockers block both Beta 1 and Beta 2 receptors thus affecting both the heart and lungs.️️a. selective b. non-selective Metoprolol is an example of a️️selective beta blocker Propranolol is an example of a️️nonselective beta blocker.
