A drug that relieves asthma by widening the bronchial tubes in the lungs.
A sympathomimetic drug used to dilate the air passages in asthma and other bronchial conditions. It also stimulates the heart and is used to treat some heart conditions involving reduced heart activity. It is administered by inhalation, by mouth, by injection, or in suppositories. Side-effects such as increased heart rate, palpitations, chest pain, dizziness, and fainting may occur.
Isoprenaline is occasionally used as an emergency remedy for heart block or extreme bradycardia (exceptionally slow heart rate). While it was once prescribed for asthma, it has been supplanted by medications with fewer adverse reactions.
