Adenocard

Definition

Adenocard is a brand name for adenosine, a medication used to treat certain types of supraventricular tachycardia by slowing down the heart rate. It works by blocking faulty electrical signals in the heart that cause irregular rhythms.

5 Must Know Facts For Your Next Test

1. Adenocard is commonly used in emergency settings for rapid conversion of paroxysmal supraventricular tachycardia (PSVT) to normal sinus rhythm.
2. The usual initial dose of Adenocard is 6 mg administered as a rapid intravenous push, followed by saline flush.
3. Adenosine has an extremely short half-life of less than 10 seconds, which necessitates rapid administration and immediate follow-up with saline flush.
4. Common side effects include flushing, chest discomfort, and transient arrhythmias; however, these are typically short-lived due to its rapid clearance.
5. Contraindications for Adenocard include second- or third-degree AV block, sick sinus syndrome without a pacemaker, and known hypersensitivity to adenosine.
