Adenosine is a nucleoside composed of adenine and ribose [1]. It plays a crucial role in cellular energy metabolism and is a component of DNA and RNA [2]. Adenosine also functions as a neurotransmitter in the brain [3].
How is Adenosine Used Medically?
In medical settings, adenosine is administered intravenously as an antiarrhythmic medication to treat certain types of supraventricular tachycardia (SVT) [4]. It works by slowing conduction through the atrioventricular (AV) node, which can help restore a normal heart rhythm [4]. Adenosine is also used during cardiac catheterization procedures to induce vasodilation and assess coronary artery disease [5].
What are the Side Effects of Adenosine?
When administered intravenously, adenosine can cause transient side effects such as flushing, shortness of breath, chest discomfort, and dizziness [4]. These effects are typically short-lived due to the drug's rapid metabolism [4].
What Happens if You Get Too Much Adenosine?
An overdose of adenosine could lead to significant slowing of the heart rate (bradycardia) or even transient heart block. Medical professionals monitor patients closely during adenosine administration to manage these potential effects [4].
How Does Adenosine Work in the Body?
Adenosine exerts its effects by binding to specific adenosine receptors on cell surfaces [3]. In the heart, it binds to A1 receptors, which decreases the heart's electrical conduction speed [4]. In the brain, it acts as an inhibitory neurotransmitter, contributing to feelings of tiredness and promoting sleep [3].
Are There Different Types of Adenosine Receptors?
Yes, there are four known types of adenosine receptors: A1, A2A, A2B, and A3 [3]. These receptors are found in various tissues throughout the body and mediate different physiological responses when activated by adenosine [3].
