The most common side effect of adenosine is flushing of the skin which is a sudden feeling of warmth and redness in your face.
The flushing of the face and skin is often also accompanied by discomfort in the chest and shortness of breath along with possible throat and neck discomfort.
The side effects of adenosine are often mild and short lived because the body breaks down adenosine rapidly.
Adenosine causes your blood vessels to dilate which leads to the sensation of flushing.
Most side effects of adenosine subside within a few seconds to a few minutes after the adenosine infusion is stopped and over.
Adenosine is made of adenine attached to a ribose sugar molecule "ribofuranose" moiety.
The bond which attaches the adenine and the ribose sugar is called a β-N9-glycosidic bond.
And the usual plasma adenosine level is between 0.4 and 0.2 micromoles.
The drug adenosine blocks electrical signals in your heart which cause irregular heart rhythms.
Adenosine can also prevent changes in energy metabolism which cause weight loss in people that have advanced cancer.
