Adenosin Life Medical (Adenosine)
Adenosin Life Medical (Adenosine) Uses, Dosage, Side Effects, Food Interaction and all others data.
This preparation is a sterile, nonpyrogenic solution for rapid bolus intravenous injection. Adenosin Life Medical (Adenosine) injection slows conduction time through the A-V node, can interrupt the reentry pathways through the A-V node, and can restore normal sinus rhythm in patients with paroxysmal supraventricular tachycardia.
Adenosin Life Medical (Adenosine) is indicated as an adjunct to thallium-201 in myocardial perfusion scintigraphy and also indicated for conversion of sinus rhythm of paroxysmal supraventricular tachycardia. Adenosin Life Medical (Adenosine) has a short duration of action as the half life is 12,13 Patients should be counselled regarding the risk of cardiovascular side effects, bronchoconstriction, seizures, and hypersensitivity.

Uses
Intravenous Adenosin Life Medical (Adenosine) is used for the following: Conversion to sinus rhythm of paroxysmal supraventricular tachycardia (PSVT), including that associated with accessory bypass tracts (Wolff-Parkinson-White Syndrome).
Adenosin Life Medical (Adenosine) is also used to associated treatment for these conditions: Paroxysmal Supraventricular Tachycardia, SVT, Tachycardia, Supraventricular, Symptomatic pulmonary arterial hypertension (PAH)
How Adenosin Life Medical (Adenosine) works
Agonism of adenosine receptors A1 and A2 reduces conduction time in the atrioventricular node of the heart. Conduction time is decreased by inducing potassium efflux and inhibiting calcium influx through channels in nerve cells, leading to hyperpolarization and and increased threshold for calcium dependent action potentials. Decreased conduction time leads to an antiarrhythmic effect. Inhibition of calcium influx, reduces the activity of adenylate cyclase, relaxing vascular smooth muscle. Relaxed vascular smooth muscle leads to increased blood flow through normal coronary arteries but not stenotic arteries, allowing thallium-201 to be more readily uptaken in normal coronary arteries.
Dosage
Adenosin Life Medical (Adenosine) dosage
Adult:
Initial dose: 6 mg given as rapid IV bolus (administered over 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 rapid intravenous bolus. This 12 mg dose may be repeated for second time if required.
Pediatric:
The dosages used in neonates, infants, children and adolescents were equivalent to those administered to adults on a weight basis.
- Body weight < 50 kg: Initial dose - 0.05 to 0.1 mg/kg as a rapid IV bolus given either centrally or peripherally. A saline flush should follow.
- Body weight > 50 kg: The adult dose is recommended. Doses greater than 12 mg are not recommended for adult and pediatric patients
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. A saline flush should follow. This process should continue until sinus rhythm is established or a maximum single dose of 0.3 mg/kg is used.
Side Effects
Cardiovascular: Facial flushing, headache, sweating, palpitations, chest pain, hypotension. Respiratory: Shortness of breath/dyspnea, chest pressure, hyperventilation, head pressure.
Central Nervous System: Lightheadedness, dizziness, tingling in arms, numbness, apprehension, blurred vision, burning sensation, heaviness in arms, neck and back pain.
Gastrointestinal: Nausea, metallic taste, tightness in throat, pressure in groin. In post-market clinical experience with Adenosin Life Medical (Adenosine), cases of prolonged asystole, ventricular tachycardia, ventricular fibrillation, transient increase in blood pressure, bradycardia, hypotension, atrial fibrillation and bronchospasm, in association with Adenosin Life Medical (Adenosine) use, have been reported.
Toxicity
Patients experiencing an overdose of adenosine may present with asystole, heart block, or cardiac ischemia; though the effects are generally short lived. Patients experiencing an overdose should be treated with symptomatic and supportive care, which may include a slow intravenous injection of theophylline.
The LD50 in mice is >20 g/kg subcutaneously, 500mg/kg intraperitoneally, and 39.6 µg/kg subcutaneously.[L32048]
Interaction
Intravenous Adenosin Life Medical (Adenosine) injection has been effectively administered in the presence of other cardioactive drugs, such as Quinidine, beta- adrenergic blocking agents, Calcium channel blocking agents and angiotensin converting enzyme inhibitors without any change in the adverse reaction profile. Digoxin and Verapamil use may be rarely associated with ventricular fibrillation when combined with Adenosin Life Medical (Adenosine). Because of the potential for additive or synergistic depressant effects on the SA and AV nodes, however, Adenosin Life Medical (Adenosine) should be used with caution in the presence of these agents. The use of Adenosin Life Medical (Adenosine) in patients receiving Digitalis may be rarely associated with ventricular fibrillation. The effects of Adenosin Life Medical (Adenosine) are antagonized by Methylxanthines, such as, Caffeine and Theophylline.
Food Interaction
- Avoid caffeine. Caffeine may antagonise the activity of adenosine.
[Moderate] ADJUST DOSING INTERVAL: Caffeine and other xanthine derivatives (e.g., theophylline) are nonspecific, competitive antagonists of adenosine receptors and may interfere with the hemodynamic effects of adenosine.
There have been case reports of patients receiving theophylline who required higher than normal dosages of adenosine for the treatment of paroxysmal supraventricular tachycardia.
In studies of healthy volunteers, caffeine and theophylline have been shown to reduce the cardiovascular response to adenosine infusions (i.e., heart rate increases, vasodilation, blood pressure changes), and theophylline has also been shown to attenuate adenosine-induced respiratory effects and chest pain
MANAGEMENT: Clinicians should be aware that adenosine may be less effective in the presence of xanthine derivatives including caffeine.
Patients should avoid consumption of caffeine-containing products for at least 12 hours, preferably 24 hours, prior to administration of adenosine for myocardial perfusion imaging.

Contraindication
Intravenous Adenosin Life Medical (Adenosine) is contraindicated in:
- 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).
- Known hypersensitivity to Adenosin Life Medical (Adenosine).
Acute Overdose
The half-life of Adenosin Life Medical (Adenosine) 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 Adenosin Life Medical (Adenosine).
Storage Condition
Store in cool dry place protected from light. Keep out of reach of children. 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.
