Orciprenaline: Presentations, Administration, Side Effects, Dosage and Precautions

It belongs to a class of medications known as bronchodilators.

It is used to relieve symptoms associated with asthma , chronic bronchitis , emphysema, and other lung conditions. It works by opening the airways, making breathing easier.

Controlling these symptoms can decrease time lost from work or school. Metaproterenol is a bronchodilator (beta-2 receptor agonist) that works by opening the airways to make breathing easier. This medicine is also known as orciprenaline in other countries.
