It activates G protein–coupled inward rectifying K+ channels and IKAdo. Adenosine hyperpolarizes the sinoatrial node and shortens the action potential durations in atrial and AV node tissue. In: Post TW, ed. Group of drugs that are used to restore sinus rhythm in patients presenting with cardiac … Adenosine can precipitate bronchospasm in asthmatics. Adenosine is an adenosine A1 receptor activator, activating A1 receptors in supraventricular tissue (sinoatrial node, atrial tissue and atrioventricular node). UpToDate. Giardina EG, Zimetbaum PJ.

Adenosine is a class IIe antiarrhythmic agent as per the Modernized Classification of Cardiac Antiarrhythmic Drugs [1]. Several classes of antiarrhythmics, including beta blockers, calcium channel blockers, amiodarone, cardiac glycosides, and lidocaine, also have other medical uses, which are discussed in their respective articles.
