Adenosine is a naturally occurring nucleoside that plays a vital role in many bodily functions, including cardiovascular regulation and cellular energy transfer [1]. It is also utilized as an active pharmaceutical ingredient (API) in certain medical treatments.
What medical conditions does Adenosine API treat?
Adenosine API is primarily used to treat supraventricular tachycardia (SVT), a type of rapid heart rhythm originating above the ventricles [2]. It can also be used during cardiac catheterization procedures to help identify coronary artery disease [3].
How does Adenosine API work?
As a medication, adenosine acts as a vasodilator, meaning it widens blood vessels. It also slows down electrical conduction through the atrioventricular (AV) node of the heart [2]. This temporary slowing of the AV node can interrupt abnormal electrical pathways that cause SVT, allowing normal heart rhythm to resume [2][4].
What are the common side effects of Adenosine API?
Patients receiving adenosine may experience transient side effects such as flushing, shortness of breath, chest discomfort, and headache [2]. These effects are typically short-lived due to the drug's rapid metabolism in the body [4].
How is Adenosine API administered?
Adenosine is administered intravenously, typically as a rapid bolus injection [2]. Its extremely short half-life, measured in seconds, means it is quickly broken down by enzymes in the blood and tissues [4].
When does patent exclusivity expire for Adenosine?
As adenosine is a naturally occurring compound, it has long been off-patent as a standalone drug. Its use as a generic medication means there is no patent-protected exclusivity for the API itself [5].
Are there any alternative treatments for Supraventricular Tachycardia?
Other treatments for SVT include vagal maneuvers, which stimulate the vagus nerve to slow heart rate, and certain antiarrhythmic medications [6]. In some cases, catheter ablation, a procedure that uses heat or cold to destroy small areas of heart tissue causing the arrhythmia, may be considered [6].
