Isoprenaline
Isoprenaline
Isoprenaline (pronounced: ahy-soh-prehn-uh-leen), also known as isoproterenol, is a medication and hormone that is primarily used in the treatment of heart block and asthma. It is a non-selective beta adrenergic agonist that stimulates the beta receptors of the heart, leading to increased heart rate and contractility.
Etymology
The term "Isoprenaline" is derived from the Greek words "iso" meaning "equal" and "prenaline" which is a synthetic form of adrenaline. The term "isoproterenol" is a combination of "iso", "proter" meaning "before" and "nol" referring to the chemical structure of the compound.
Usage
Isoprenaline is used in the treatment of bradycardia (slow heart rate), heart block, and asthma. It works by stimulating the beta receptors in the heart, causing an increase in heart rate and contractility. In asthma, it helps to relax the muscles in the airways, making it easier to breathe.
