Adenosine - definition from

[(Science: biochemistry) a ribonucleotide which consists of the nitrogenous base adenine linked to the sugar ribose. (Science: drug) a cardiac drug used in terminating PSVT involving reentry pathways that include the av node or wolff-parkinson-white syndrome. For atrial flutter, atrial fibrillation, atrial or ventricular tachycardias, adenosine may produce transient av block that may help identify the rhythm. pharmacologic action: endogenous purine nucleoside that depresses av node and sinus node activity. brief duration of action (1-2 min). Dose: Rapid 6 mg iv bolus over 1-3 sec. May repeat at 12 mg iv bolus within 1-2 min patients taking theophylline may require larger doses. use a smaller dose with cardiac transplant patients. potential complications: Common but transient - flushing, dyspnea, chest pain, bradycardia, and ventricular ectopy.
