Welcome back in this video we’ll talk about the most common beer blockers their uses and side effects these are the medications ending with the sufflix lol like propranolol achinalol labitolol and esmolol in our bodies we have beta-1 receptors beta2 and br3 receptors these medications antagonize br1 receptor more than beta2 receptors and as we know beta1
Receptor is found in the heart so they antagonize the adrenergic system in the heart slowing it down and decreasing the heart rate so it makes sense that we use these medications in cases of angina and supraventricular tachycardia and these medications have equal effect on beta 1 and beta2 beta2 receptors are found in our lungs and they maintain an open
Airway so beta2 agonists cause bronchoconstriction that’s why these medications are contraindicated in asthmatic patients remember beta1 works in the heart because we have one heart and beara two works in the lungs because we have two lungs carvidaol and labitalol antagonize both alpha and beta receptors which means we can use these medications in cases of fear
