  1、 Adenosine  is  a vasodilator  and also can be used as antiarrhythmic drug.The main indications include:

  （1）Paroxysmal supraventricular tachycardia. For the treatment of paroxysmal supraventricular tachycardia  participation in the atrioventricular node reentry ,Adenosine is very effective as a drug of choice for treatment. Because of its short half-life and insignificant side effects, it can also be used when verapamil is ineffective or contraindicated.

  （2）Differential diagnosis of ventricular tachycardia.

  （3）Adjuvant of  thallium-201 myocardial perfusion imaging. 

  2、Adenosine is used for the synthesis of adenosine triphosphate (ATP), Adenosine 5'-monophosphate(AMP), Vidarabine, coenzyme A and other important intermediates.

  3、Adenosine can stimulate hair growth to reduce hair loss.
