Adenoscan

Adenoscan is an intravenous drug containing adenosine, an endogenous nucleoside that acts as a potent vasodilator in most vascular beds. It helps dilate the coronary arteries, simulating the physiological effects of exercise to assist in detecting coronary artery disease during cardiac imaging.
