Intravenous Adenocard (adenosine injection) is indicated for the following.
Conversion to sinus rhythm of paroxysmal supraventricular tachycardia (PSVT), including that associated with accessory bypass tracts (Wolff-Parkinson-White Syndrome). When clinically advisable, appropriate vagal maneuvers (e.g., Valsalva maneuver), should be attempted prior to Adenocard administration.
It is important to be sure the Adenocard solution actually reaches the systemic circulation (see Dosage and Administration).
Adenocard does not convert atrial flutter, atrial fibrillation, or ventricular tachycardia to normal sinus rhythm. In the presence of atrial flutter or atrial fibrillation, a transient modest slowing of ventricular response may occur immediately following Adenocard administration.
For rapid bolus intravenous use only.
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.
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.
The recommended intravenous doses for adults are as follows:
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.
The dosages used in neonates, infants, children and adolescents were equivalent to those administered to adults on a weight basis.
Initial dose: 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.
Administer the adult dose.
Doses greater than 12 mg are not recommended for adult and pediatric patients.
NOTE: Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration.
The half-life of Adenocard (adenosine injection) is less than 10 seconds. Thus, adverse effects are generally rapidly self-limiting. Treatment of any prolonged adverse effects should be individualized and be directed toward the specific effect. Methylxanthines, such as caffeine and theophylline, are competitive antagonists of adenosine.
Store at controlled room temperature 15º-30ºC (59º-86ºF).
DO NOT REFRIGERATE as crystallization may occur. If crystallization has occurred, dissolve crystals by warming to room temperature. The solution must be clear at the time of use.
Contains no preservatives. Discard unused portion.
May require needle or blunt. To prevent needle-stick injuries, needles should not be recapped, purposely bent or broken by hand.
