What is the classification of Adenosine (Adenocard)?

Adenosine (Adenocard) is classified as an antidysrhythmic agent primarily due to its ability to rapidly restore normal sinus rhythm in patients experiencing certain types of supraventricular tachycardia (SVT). It works by temporarily slowing conduction through the AV node, which can interrupt reentry pathways that are responsible for the tachycardic rhythm. Its fast onset and short duration of action make it particularly effective in acute situations such as a tachyarrhythmia.

Other classifications that may seem relevant, such as those involving endogenous nucleosides or bronchodilators, do not accurately describe the primary therapeutic role of adenosine in the context of emergency medicine or its use as a medication. While adenine and other endogenous nucleosides are biologically significant in various physiological processes, adenosine's clinical application and importance in the context of dysrhythmias firmly establishes it as an antidysrhythmic drug.
