Adrenaline vs. Adrenalin — What's the Difference?
By Tayyaba Rehman & Maham Liaqat — Updated on March 25, 2024
Adrenaline, a hormone and medication, is crucial for the fight-or-flight response, enhancing heart rate and energy. Adrenalin, its alternative spelling, highlights the same biochemical role.

Key Differences
Adrenaline is a hormone and neurotransmitter secreted by the adrenal glands, playing a vital role in the body's fight-or-flight response by increasing heart rate, muscle strength, and blood pressure. On the other hand, Adrenalin refers to the same chemical substance, with the difference lying primarily in the spelling, which is used less commonly in scientific and medical communities today.
The term "Adrenaline" is widely used in medical and scientific literature to describe the hormone that prepares the body to respond to physical or psychological stress. Whereas "Adrenalin" is often seen in historical contexts or in certain brand names, suggesting a variation in usage based on region or tradition rather than any difference in chemical composition.
Adrenaline's effects on the body are immediate and powerful, including rapid heartbeat, increased force of heart contractions, and dilated air passages, which collectively enhance the body’s ability to perform under stress. Adrenalin, while chemically identical, is a term that may appear in less technical discussions or in the naming of pharmaceutical products, emphasizing its role in emergency medicine and treatments.
In therapeutic uses, adrenaline is administered for conditions such as anaphylaxis, cardiac arrest, and asthma attacks, showcasing its critical role in emergency medical interventions. Adrenalin, under this name, may also be found in medications and products intended for similar purposes, although the preference for "adrenaline" in clinical settings underscores standardization in medical terminology.
The distinction between adrenaline and adrenalin becomes most apparent in the context of their application and the preference for terminology among professionals. While adrenaline is the preferred term in most scientific and medical discussions, adrenalin serves as a reminder of the historical and variational nature of language in the field of biochemistry and medicine.

Adrenaline
Produced by the adrenal glands during stress.
His body flooded with adrenaline at the sound of the alarm.
Adrenalin
A catecholamine secreted by the adrenal medulla in response to stress (trade name Adrenalin); stimulates autonomic nerve action
Adrenaline
Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration). Adrenaline is normally produced both by the adrenal glands and by a small number of neurons in the medulla oblongata.
Adrenaline
See epinephrine.
Adrenaline
(hormone) epinephrine, the hormone and neurotransmitter.
Adrenaline
Excitement; thrills.
Adrenaline
A hormone secreted by the adrenal medulla that acts as a powerful stimulant in reponse to fear or stress; it stimulates autonomic nerve action. It can be obtained as a crystalline substance, C9H13NO3. It is used in medicine as a vasoconstrictor (hemostatic) and cardiac stimulant, also to reduce allergic reactions and to stimulate the heart in cases of cardiac arrest.
