What is Adenosine

Science Facts


Adenosine is the chemical compound found in mammalian cells.They are mainly exit in 3 major forms:

  1. Adenosine
  2. Adenosine monophosphate
  3. Adenosine triphosphate

Adenosine prevents the electrical impulses which cause irregular heartbeat.


History of adenosine

It was first used in SVT in 1976 it displaced the verapamil (first line drug) for SVT. Two most talented scientists Cyrus H.fiske Yellapragada Subbarow determined the adenosine in mammalian cells and liver.

Adenosine Chemical Compound

It is a ribonucleoside compound formed by adenine adhere to ribofuranose via a beta-N(9)-glycosidic bond.It can be used as an antiarrhythmic drug, , a painkiller,or a vasodilator agent.

What is Adenosine

Adenosine Uses

  1. SVT
  2. Arrhythmia
  3. its help in vasodilation in the condition of arteriosclerosis

Adenosine Administrative Route

It can be given as intravenous or in the form of adenosine injection.

Adenosine Side Effects

  • Dyspnea
  • Angina pectoris
  • Convulsions
  • Nausea
  • Dizziness

Adenosine Deaminase

Enzyme of purine group which helps in acceleration of irreversible deamination of adenosine.

Adenosine Deaminase Deficiency

It is a genital disorder that affects the immune system. Patients suffering from ADA are prone to bacterial, viral, and fungal infection.

  1. Indications
  2. Pneumonia
  3. Chronic diarrhea
  4. Rashes


It is caused due to alteration in ADA gene.Adenosine deaminase found in all over the body but mostly in wbcs( lymphocytes).


  1. Gene therapy
  2. Chemotherapy

Why does adenosine stop the heart?

Adenosine is given intravenously. it will adhere to av nodes and stop irregularity of heartbeat
