Carbamazepine has been reported to increase the degree of heart block produced by other agents. As the primary effect of adenosine is to decrease conduction through the A-V node, higher degrees of heart block may be produced in the presence of carbamazepine.

Chronically high levels of adeonsine are associated with Adenosine Deaminase Deficiency.

Other drug-drug interactions to consider when administering adenosine is the simultaneous use of carbamazepine and dipyridamole. Both these drugs may enhance the adverse effects of adenosine; the clinician should use a decreased initial dose.

Adenosine slows conduction time through the AV node and can interrupt the reentry pathways through the AV node, resulting in the restoration of normal sinus rhythm in patients with paroxysmal supraventricular tachycardia (PSVT), including PSVT associated with Wolff-Parkinson-White Syndrome. This effect may be mediated through the drug's activation of cell-surface A₁ and A₂ adenosine receptors. Adenosine also inhibits the slow inward calcium current and activation of adenylate cyclase in smooth muscle cells, thereby causing relaxation of vascular smooth muscle. By increasing blood flow in normal coronary arteries with little or no increase in stenotic arteries (with little to no increase in stenotic arteries), adenosine produces a relative difference in thallous (th...

/OTHER TOXICITY INFORMATION/ Priapism is defined as abnormal prolonged penile erection lasting at least for 4 hours occurring without sexual interest. Forty percent of sickle cell disease (SCD) patients display priapism. The disorder is dangerous and urgent given its association with ischemia-mediated erectile tissue damage and subsequent erectile dysfunction. Current strategies to manage the disorder are poor due to lack of fundamental understanding of the molecular mechanisms of priapism. Adenosine is a signaling nucleoside that elicits many pathophysiological effects by engaging membrane receptors. Recent evidence shows that adenosine may play an important role in priapism via adenosine receptor. ...To summarize the recent findings on the importance of adenosine signaling in the path...

In general, Adenocard in geriatric patients should be used with caution since this population may have a diminished cardiac function, nodal dysfunction, concomitant diseases or drug therapy that may alter hemodynamic function and produce severe bradycardia or AV block.
