What is a common administration route for adenosine?

Adenosine is commonly administered via the intravenous route due to its pharmacokinetic properties. When given IV, adenosine acts very quickly, making it particularly useful in acute situations, such as the treatment of certain types of supraventricular tachycardia. The intravenous route allows for rapid distribution and immediate effect, which is critical in emergency settings. Adenosine has a very short half-life, roughly 10 seconds, which further supports its effectiveness when administered directly into the bloodstream.

Other routes, such as oral or subcutaneous, would not provide the rapid onset required for conditions treated with adenosine. Inhalation is also not a viable route for administering adenosine as there are no formulations or mechanisms for effective delivery through this method for the specific therapeutic goals sought with adenosine. This is why, in the context of acute management, intravenous administration is the preferred and common route for adenosine.
