Isoprenaline (Isoproterenol) (Isoprenaline (also known as Isoproterenol)) — Uses, Dosage, Side Effects & Safety

Drug class: Sympathomimetic (Non-selective beta-adrenergic agonist)

Overview

Isoprenaline (Isoproterenol) is a medication used to treat certain heart problems, such as bradycardia (slow heart rate), heart block, and sometimes for asthma or bronchospasm when other treatments are not effective. It works by stimulating beta-adrenergic receptors in the heart and lungs, which increases heart rate, improves heart muscle contractions, and relaxes airway muscles. This medicine is usually given in a hospital setting under close supervision, especially when used for heart rhythm problems. Patients should know that Isoprenaline acts quickly and its effects wear off rapidly once stopped. It is not a first-line treatment for asthma or chronic obstructive pulmonary disease (COPD), but may be used in emergencies. Key points: Isoprenaline can cause side effects like palpitations, headache, and flushing. It should only be used as directed by a healthcare professional, and patients should report any chest pain, severe dizziness, or difficulty breathing immediately.
