Adenosine is a naturally occurring nucleoside that plays a crucial role in various physiological processes within the body. It is composed of adenine, a purine base, and ribose, a sugar molecule.
What does adenosine do in the body?
Adenosine functions as a neuromodulator in the brain, influencing sleep and wakefulness by inhibiting neural activity. It also plays a role in cardiovascular regulation, acting as a vasodilator which widens blood vessels to improve blood flow. Additionally, adenosine is involved in energy metabolism, as it is a component of adenosine triphosphate (ATP), the primary energy currency of cells. Its presence can also affect platelet aggregation and inflammation [1].
How is adenosine used in medicine?
Medically, adenosine is administered intravenously to treat certain heart rhythm disorders, specifically paroxysmal supraventricular tachycardia (PSVT). When given rapidly, it can interrupt abnormal electrical pathways in the heart, restoring a normal heart rhythm [1].
What are the potential side effects of adenosine?
The administration of adenosine can cause transient side effects due to its rapid metabolism. These commonly include flushing, shortness of breath, chest discomfort, and a brief feeling of impending doom. Cardiac side effects such as bradycardia (slow heart rate) and transient asystole (cessation of heart beat) can also occur, though they are typically self-limiting [1].
Are there any alternatives to adenosine for heart rhythm issues?
Other medications, such as beta-blockers and calcium channel blockers, are also used to manage supraventricular tachycardia. Vagal maneuvers, which involve stimulating the vagus nerve, can also be effective in terminating episodes of PSVT [1].
