Isoproterenol hydrochloride (Medihaler-Iso®) is a beta adrenergic receptor agonist medication, used as an inhaled aerosol to treat asthma. Although it activates all beta adrenergic receptors, it works in a similar fashion to the more selective beta2-adrenergic receptor agonists 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.

It is structurally similar to epinephrine but acts for the most part on beta receptors.
