Isoproterenol: Chemical Structure, Mechanism of Action, Uses & Side Effects

Chemical Structure/Formula:

• C11H17NO3

Structure of Isoproterenol

Mechanism of Action:

• Isoproterenol is a synthetic non-selective beta-adrenergic agonist.

• it stimulates both beta-1 and beta-2 receptors, leading to increased heart rate, improved myocardial contractility, and bronchodilation.

• It can also cause peripheral vasodilation due to beta-2 effects.

Uses:

• Its primary uses include treating bradycardia (especially in heart block), bronchospasm during anesthesia, and asthma.

• It's often used when other more selective medications are ineffective or contraindicated.

Side Effects:

• Due to its non-selective action, side effects can include palpitations, tachycardia, chest pain, tremor, headache, and anxiety.
