==Overview==
|lookAlike=
'''Isoproterenol hydrochloride''' or '''isoprenaline''' (Medihaler-Iso®) is a [[sympathomimetic]] beta [[adrenergic receptor]] [[agonist]] [[medication]].
It is structurally similar to [[epinephrine]] but acts for the most part on [[beta receptor]]s.
* A® — B®<ref name="www.ismp.org">{{Cite web | last = | first = | title = http://www.ismp.org | url = http://www.ismp.org | publisher = | date = }}</ref>
==Uses==
<!--Drug Shortage Status-->
It is used as an inhaled aerosol to treat [[asthma]]. Although it activates all beta [[adrenergic receptor]]s, it works in a similar fashion to the more selective [[beta2-adrenergic receptor agonist]]s e.g. [[salbutamol]], by relaxing the airways to increase airflow.
It is also supplied in ampules under the brand name Isuprel® for injection and in [[sublingual]] pill form for treatment of [[asthma]], chronic [[bronchitis]] and [[emphysema]].
|drugShortage=
}}
Used with caution, it can also be used to treat [[torsades de pointes]], in conjunction with overdrive pacing and magnesium.
<!--Pill Image-->
==Pharmacology==
{{PillImage
Isoproterenol is a β<sub>1</sub>- and β<sub>2</sub>-[[adrenoceptor]] agonist which was commonly used to treat asthma before the more widespread use of [[salbutamol]], which has more selective effects on the airways. Its [[route of administration]] is either intravenous, oral, intranasal, subcutaneous, or intramuscular, depending on use. The plasma half-life for isoproterenol is approximately two hours.

Isoproterenol's effects on the [[cardiovascular system]] relate to its actions on cardiac β<sub>1</sub> receptors and β<sub>2</sub> receptors on skeletal muscle [[arteriole]]s. Isoproterenol has positive [[inotropy|inotropic]] and [[chronotropy|chronotropic]] effects on the heart. In skeletal muscle arterioles it produces vasodilatation. Its inotropic and chronotropic effects elevate [[systolic blood pressure]], while its vasodilatory effects tend to lower [[diastolic blood pressure]].
<!--Label Display Image-->
The adverse effects of isoproterenol are also related to the drug's cardiovascular effects. Isoproterenol can produce an elevated [[heart rate]] ([[tachycardia]]), which predisposes patients to [[cardiac dysrhythmia]]s.
