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. In humans, it is a non-selective β adrenoreceptor agonist and TAAR1 agonist that is structurally similar to epinephrine (adrenaline).
