Mechanism of Adenosine-Lopinavir Interaction (Severity Level: Moderate)
Increased risk of ventricular arrhythmias Click to Show/Hide Mechanism Graph
Drug Name		Adenosine				Lopinavir
Mechanism 1		Bradycardia				Prolong QT interval
Key Mechanism Factor 1
		Factor Name		Ventricular arrhythmias
		Factor Description		Ventricular arrhythmias are abnormal heart rhythms that cause your heart's lower chambers to pump blood instead of pumping it. This can limit or stop your heart from supplying blood to your body. While some of these arrhythmias are harmless and do not cause symptoms, others can have serious, even fatal, effects on your body.
Mechanism Description		Increased risk of ventricular arrhythmias by the combination of Adenosine and Lopinavir
Mechanism 2		Delay atrioventricular conduction				Prolong QT interval
Key Mechanism Factor 2
		Factor Name		Ventricular arrhythmias

This can limit or stop your heart from supplying blood to your body. While some of these arrhythmias are harmless and do not cause symptoms, others can have serious, even fatal, effects on your body.
Mechanism Description		Increased risk of ventricular arrhythmias by the combination of Adenosine and Lopinavir

Recommended Action
Management		Adenosine should be used with caution in patients receiving drugs that may prolong the QT interval. Adenosine should be discontinued immediately if severe bradycardia occurs.
