Orciprenaline, also known as metaproterenol, is medication used to treat asthma and COPD. It is taken by mouth or inhaled. The medications salbutamol or terbutaline are preferred as they are more effective with less side effects.

Common side effects include anxiety, tremor, headache, palpitations, trouble sleeping, diarrhea, and itchiness. Other side effects may include low potassium and bronchospasm. It is a β2 adrenergic receptor agonist that relaxes smooth muscle in the airways.

Orciprenaline was approved for medical use in the United States in 1973. In the United States 90 tablets of 20 mg costs about 54 USD as of 2021. It was withdrawn from the market in the United Kingdom in 2010.
