ISOPRENALINE Meaning and
Definition
-
Isoprenaline, also known as isoproterenol, is a synthetic medication classified as a non-selective β-adrenergic agonist, meaning it activates receptors in the body's sympathetic nervous system that are responsible for the fight-or-flight response. It works by mimicking the effects of natural substances called catecholamines, such as adrenaline, on the β-adrenergic receptors.
Isoprenaline is primarily used for its bronchodilator properties in the treatment of asthma, bronchitis, and other respiratory conditions. By activating the β2-adrenergic receptors in the airway, it relaxes the smooth muscles in the bronchioles, widening the air passages and resulting in easier breathing for patients experiencing bronchospasms.
In addition to its respiratory effects, isoprenaline also acts on the heart by stimulating β1-adrenergic receptors, leading to an increase in heart rate, force of contraction, and cardiac output. Therefore, it can be utilized to treat certain cardiac conditions, such as bradycardia (slow heart rate), heart block, and cardiac arrest.
Furthermore, isoprenaline may be employed during certain medical procedures to produce controlled increases in heart rate, aiding in the diagnosis of cardiac disorders.
Isoprenaline is typically administered via inhalation or injection, depending on the indication and desired effect. Although it has proven to be effective in various medical settings, it should be used with caution due to potential side effects, such as palpitations, tremors, headache, and increased blood pressure.

Etymology of ISOPRENALINE
The word "Isoprenaline" is derived from a combination of two components: "iso-" and "adrenaline".
1. "Iso-" is a prefix derived from the Greek word "isos", meaning "equal" or "same". In scientific terminology, it is used to signify that the compound is an isomer or isoform of a particular substance.
2. "Adrenaline" is a hormone and neurotransmitter present in the body, known as epinephrine. It is secreted by the adrenal glands and plays a vital role in the body's "fight or flight" response to stress, increasing heart rate, dilating air passages, and mobilizing energy.
Therefore, "isoprenaline" indicates that the compound is an isomer of adrenaline, with a similar structure and pharmacological activity. It is also known as isoproterenol.
