These drugs are often used to treat high blood pressure when other medications haven't worked. Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline.
Hi! I thought beta blockers working on B1 increased HR and cardiac contraction, also I thought that beta blocker means antagonist not agonist so a B2 blocker would give an inhibitory action therefore a Lung contraction. I just want to make sure that I'm informed right.
