Q; 52 year old female went into supraventricular tachycardia. While you call for Adenosine at bedside, clinical pharmacist inform you that patient is on chronic Aggrenox for her stroke?

Answer: Aggrenox is the combination of Aspirin and extended release Dipyridamole. Dipyridamole potentiates the action of adenosine so the lower doses (usually half) should be given. Give only half of recommended dose of Adenosine.
