Overview

Adenosine is an adenosine receptor agonist and antiarrhythmic that is FDA approved for the {{{indicationType}}} of paroxysmal supraventricular tachycardia (PSVT), including that associated with accessory bypass tracts (Wolff-Parkinson-White syndrome).. Common adverse reactions include chest discomfort, flushing, abdominal discomfort, pain of head and neck region, dizziness, headache, and dyspnea.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Paroxysmal Supraventricular Tachycardia

• Adenocard (adenosine injection) should be given as a rapid bolus by the peripheral intravenous route. To be certain the solution reaches the systemic circulation, it should be administered either directly into a vein or, if given into an IV line, it should be given as close to the patient as possible and followed by a rapid saline flush.

Adult Patients

• The dose recommendation is based on clinical studies with peripheral venous bolus dosing. Central venous (CVP or other) administration of Adenocard has not been systematically studied.

• Dosing Information

• Initial dose: 6 mg given as a rapid intravenous bolus (administered over a 1-2 second period).
• Repeat administration: If the first dose does not result in elimination of the supraventricular tachycardia within 1-2 minutes, 12 mg should be given as a rapid intravenous bolus. This 12 mg dose may be repeated a second time if required.

Pediatric Patients with a Body Weight < 50 kg

• Dosing Information

• Give 0.05 to 0.1 mg/kg as a rapid IV bolus given either centrally or peripherally. A saline flush should follow.
• Repeat administration: If conversion of PSVT does not occur within 1-2 minutes, additional bolus injections of adenosine can be administered at incrementally higher doses, increasing the amount given by 0.05 to 0.1 mg/kg. Follow each bolus with a saline flush. This process should continue until sinus rhythm is established or a maximum single dose of 0.3 mg/kg is used.

Pediatric Patients with a Body Weight ≥ 50 kg

• Administer the adult dose.

Off-Label Use and Dosage (Adult)

Guideline-Supported Use

Supraventricular Tachycardia

• Developed by: ACCF/AHA

• Class of Recommendation: Class I

• Strength of Evidence: Category B

• Dosing Information

• 6 mg, followed by 12 mg as needed

Non–Guideline-Supported Use

Preventing Graft Occlusion Following Aortocoronary Bypass Surgery

• Dosing Information

• Intraoperative administration of blood cardioplegia containing containing 0.5–2 mM adenosine. Patients receiving adenosine cardioplegia were also given an infusion of adenosine (200 microg/kg/min) 10 minutes before and 15 minutes after removal of the aortic crossclamp.

Percutaneous Transluminal Angioplasty

• Dosing Information

• 20 mg in 50 milliliters (mL) saline infused at a rate of 2 mg/minute

Pediatric Indications and Dosage

FDA-Labeled Indications and Dosage (Pediatric)

There is limited information regarding FDA-Labeled Use of Adenosine in pediatric patients.

Off-Label Use and Dosage (Pediatric)

Guideline-Supported Use

Supraventricular Tachycardia

• Developed by: ACCF/AHA

• Class of Recommendation: Class IIa

• Strength of Evidence: Category B

• Dosing Information

• 0.05–0.3 mg/kg

Non–Guideline-Supported Use

There is limited information regarding Off-Label Non–Guideline-Supported Use of Adenosine in pediatric patients.

Contraindications

• Second- or third-degree A-V block (except in patients with a functioning artificial pacemaker)
• Sinus node disease, such as sick sinus syndrome or symptomatic bradycardia (except in patients with a functioning artificial pacemaker)
• Hypersensitivity to adenosine

Warnings

• Heart Block

• Adenocard (adenosine injection) exerts its effect by decreasing conduction through the A-V node and may produce a short lasting first-, second- or third-degree heart block. Appropriate therapy should be instituted as needed. Patients who develop high-level block on one dose of Adenocard should not be given additional doses. Because of the very short half-life of adenosine, these effects are generally self-limiting. Appropriate resuscitative measures should be available.

• Transient or prolonged episodes of asystole have been reported with fatal outcomes in some cases. Rarely, ventricular fibrillation has been reported following Adenocard administration, including both resuscitated and fatal events. In most instances, these cases were associated with the concomitant use of digoxin and, less frequently with digoxin and verapamil. Although no causal relationship or drug-drug interaction has been established, Adenocard should be used with caution in patients receiving digoxin or digoxin and verapamil in combination.

• Arrhythmias at Time of Conversion

• At the time of conversion to normal sinus rhythm, a variety of new rhythms may appear on the electrocardiogram. They generally last only a few seconds without intervention, and may take the form of premature ventricular contractions, atrial premature contractions, atrial fibrillation, sinus bradycardia, sinus tachycardia, skipped beats, and varying degrees of A-V nodal block. Such findings were seen in 55% of patients.

• Bronchoconstriction

• Adenocard (adenosine injection) is a respiratory stimulant (probably through activation of carotid body chemoreceptors) and intravenous administration in man has been shown to increase minute ventilation (Ve) and reduce arterial PCO2 causing respiratory alkalosis.

• Adenosine administered by inhalation has been reported to cause bronchoconstriction in asthmatic patients, presumably due to mast cell degranulation and histamine release. These effects have not been observed in normal subjects. Adenocard has been administered to a limited number of patients with asthma and mild to moderate exacerbation of their symptoms has been reported. Respiratory compromise has occurred during adenosine infusion in patients with obstructive pulmonary disease. Adenocard should be used with caution in patients with obstructive lung disease not associated with bronchoconstriction (e.g., emphysema, bronchitis, etc.) and should be avoided in patients with bronchoconstriction or bronchospasm (e.g., asthma). Adenocard should be discontinued in any patient who develops severe respiratory difficulties.
