Adenosine is used in medicine particularly in the treatment of certain heart rhythm disorders such as supraventricular tachycardia (SVT). It is administered to help restore a normal heart rhythm. It is also used in diagnostic procedures such as cardiac stress tests to evaluate heart function.

The main purpose of adenosine in the body is to regulate energy and cellular activity. It helps in the formation of ATP which provides energy for various cellular functions.

Adenosine is a naturally occurring compound found in all living cells. It is a nucleoside composed of adenine (a nitrogenous base) and ribose (a sugar). It plays an essential role in biochemical processes especially in energy transfer as part of molecules like ATP (adenosine triphosphate).
