Isoprenaline (INN) or isoproterenol (USAN, trade names Medihaler-Iso and Isuprel) is a medication used for the treatment of bradycardia (slow heart rate), heart block, and rarely for asthma. Produces bronchodilation by relaxing bronchial smooth muscle through beta-2 receptor stimulation; increases heart rate and myocardial contractility by stimulating cardiac beta-1 receptors, which increases cardiac output. |
