5.1Cardiac Arrest, Ventricular Arrhythmias, and Myocardial Infarction Fatal and nonfatal cardiac arrest, sustained ventricular tachycardia (requiring resuscitation), and myocardial infarction have occurred following adenosine infusion. Avoid use in patients with symptoms or signs of acute myocardial ischemia, for example, unstable angina or cardiovascular instability; these patients may be at greater risk of serious cardiovascular reactions to adenosine injection. Appropriate resuscitative measures should be available [see Overdosage (10) ] .
5.2Sinoatrial and Atrioventricular Nodal Block Adenosine injection exerts a direct depressant effect on the SA and AV nodes and may cause first-, second- or third-degree AV block, or sinus bradycardia. In clinical trials, approximately 6% of patients developed AV block following adenosine injection administration (first-degree heart block developed in 3%, second-degree in 3%, and third-degree in 0.8% of patients) [see Clinical Trials Experience (6.1) ] . Use adenosine injection with caution in patients with pre-existing first-degree AV block or bundle branch block.
Do not use in patients with high-grade AV block or sinus node dysfunction (except in patients with a functioning artificial pacemaker). Discontinue adenosine injection in any patient who develops persistent or symptomatic high-grade AV block.
5.3Bronchoconstriction Adenosine injection administration can cause dyspnea, bronchoconstriction, and respiratory compromise. Adenosine injection should be used with caution in patients with obstructive lung disease not associated with bronchoconstriction (e.g., emphysema, bronchitis). Do not use in patients with bronchoconstriction or bronchospasm (e.g., asthma).
Discontinue adenosine injection in any patient who develops severe respiratory difficulties. Resuscitative measures should be available prior to adenosine injection administration [see Clinical Trials Experience (6.1) , Overdosage (10) , and Clinical Pharmacology (12.2) ].
5.4Hypotension Adenosine injection is a potent peripheral vasodilator and can induce significant hypotension. The risk of serious hypotension may be higher in patients with autonomic dysfunction, hypovolemia, stenotic valvular heart disease, pericarditis or pericardial effusions, or stenotic carotid artery disease with cerebrovascular insufficiency.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The following adverse reactions, with an incidence of at least 1%, were reported with adenosine injection among 1,421 patients in clinical trials. 11% of the adverse reactions occurred several hours after adenosine injection administration.
8% of the adverse reactions began with adenosine infusion and persisted for up to 24 hours. The most common (incidence ≥ 10%) adverse reactions to adenosine injection are flushing, chest discomfort, shortness of breath, headache, throat, neck or jaw discomfort, gastrointestinal discomfort, and dizziness (Table 2). Table 2 Adverse Reactions in Clinical Trials (Frequency ≥ 1%) Adverse Reactions Adenosine Injection N = 1,421 Flushing 44% Chest discomfort 40% Dyspnea 28% Headache 18% Throat, neck or jaw discomfort 15% Gastrointestinal discomfort 13% Lightheadedness/dizziness 12% Upper extremity discomfort 4% ST segment depression 3% First-degree AV block 3% Second-degree AV block 3% Paresthesia 2% Hypotension 2% Nervousness 2% Arrhythmias 1% Adverse reactions to adenosine injection of any severity reported in less than 1% of patients include: Body as a Whole : back discomfort, lower extremity discomfort, weakness Cardiovascular System : myocardial infarction, ventricular arrhythmia, third-degree AV block, bradycardia, palpitation, sinus exit block, sinus pause, T-wave changes, hypertension (systolic blood pressure > 200 mm Hg) Respiratory System : cough Central nervous System : drowsiness, emotional instability, tremors Genital/Urinary System : Vaginal pressure, urgency Special Senses : blurred vision, dry mouth, ear discomfort, metallic taste, nasal congestion, scotomas, tongue discomfort
6.2Post-Marketing Experience The following adverse reactions have been reported from marketing experience with adenosine injection. Because these reactions are reported voluntarily from a population of uncertain size, are associated with concomitant diseases and multiple drug therapies and surgical procedures, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Cardiac Disorders: cardiac arrest, atrial fibrillation, cardiac failure, myocardial infarction, tachycardia, ventricular arrhythmia Gastrointestinal Disorders: nausea and vomiting General Disorders and Administration Site Conditions: chest pain, injection site reaction, infusion site pain Immune System Disorders: hypersensitivity Nervous System Disorders: cerebrovascular accident including intracranial hemorrhage, seizure activity including tonic-clonic (grand mal) seizures, loss of consciousness Respiratory, Thoracic and Mediastinal Disorders: bronchospasm, respiratory arrest, throat tightne…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Methylxanthines interfere with the activity of adenosine injection ( 7.1 , 10 ) Nucleoside transport inhibitors such as dipyridamole can increase the activity of adenosine injection ( 7.1 )
7.1Effects of Other Drugs on Adenosine Injection The vasoactive effects of adenosine are inhibited by adenosine receptor antagonists, (such as methylxanthines (e.g., caffeine, aminophylline, and theophylline). The safety and efficacy of adenosine injection in the presence of these agents has not been systematically evaluated [see Overdosage (10) ] . The vasoactive effects of adenosine injection are potentiated by nucleoside transport inhibitors such as dipyridamole.
The safety and efficacy of adenosine in the presence of dipyridamole has not been systematically evaluated. Whenever possible, drugs that might inhibit or augment the effects of adenosine should be withheld for at least five half-lives prior to the use of adenosine injection.
7.2Effects of Adenosine Injection on Other Drugs Adenosine injection has been given with other cardioactive drugs (such as beta adrenergic blocking agents, cardiac glycosides, and calcium channel blockers) without apparent adverse interactions, but its effectiveness with these agents has not been systematically evaluated. Because of the potential for additive or synergistic depressant effects on the SA and AV nodes, however, adenosine injection should be used with caution in the presence of these agents [see Warnings and Precautions (5.2) ] .
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Pregnancy Category C . Animal reproduction studies have not been conducted with adenosine; nor have studies been performed in pregnant women. Because it is not known whether adenosine injection can cause fetal harm when administered to pregnant women, adenosine injection should be used during pregnancy only if clearly needed.
8.3Nursing Mothers It is not known whether adenosine injection is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions from adenosine injection in nursing infants, the decision to interrupt nursing after administration of adenosine injection or not to administer adenosine injection, should take into account the importance of the drug to the mother.
8.4Pediatric Use The safety and effectiveness of adenosine injection in patients less than 18 years of age have not been established.
8.5Geriatric Use Clinical studies with adenosine injection did not include sufficient numbers of subjects aged younger than 65 years to determine whether they respond differently. Other reported experience has not revealed clinically relevant differences of the response of elderly in comparison to younger patients.

🆘 Overdosage ▾
10 OVERDOSAGE The half-life of adenosine is less than 10 seconds and adverse reactions of adenosine injection usually resolve quickly when the infusion is discontinued, although delayed or persistent reactions have been observed. Methylxanthines, such as caffeine, aminophylline, and theophylline, are competitive adenosine receptor antagonists and theophylline has been used to terminate persistent adverse reactions. In clinical trials, theophylline (50 mg to 125 mg slow intravenous injection) was used to attenuate adenosine injection adverse reactions in approximately 2% of patients.
Methylxanthine use is not recommended in patients who experience seizures in association with adenosine injection [see Drug Interactions (7.1) ] .
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Adenosine causes cardiac vasodilation which increases cardiac blood flow. Adenosine is thought to exert its pharmacological effects through activation of purine receptors (cell-surface A 1 and A 2 adenosine receptors). Although the exact mechanism by which adenosine receptor activation relaxes vascular smooth muscle is not known, there is evidence to support both inhibition of the slow inward calcium current reducing calcium uptake, and activation of adenylate cyclase through A 2 receptors in smooth muscle cells.
Adenosine may also lessen vascular tone by modulating sympathetic neurotransmission. The intracellular uptake of adenosine is mediated by a specific transmembrane nucleoside transport system. Once inside the cell, adenosine is rapidly phosphorylated by adenosine kinase to adenosine monophosphate, or deaminated by adenosine deaminase to inosine.
These intracellular metabolites of adenosine are not vasoactive. Myocardial uptake of thallium-201 is directly proportional to coronary blood flow. Since adenosine injection significantly increases blood flow in normal coronary arteries with little or no increase in stenotic arteries, adenosine injection causes relatively less thallium-201 uptake in vascular territories supplied by stenotic coronary arteries i.e., a greater difference is seen after adenosine injection between areas served by normal and areas served by stenotic vessels than is seen prior to adenosine injection.
12.2Pharmacodynamics Hemodynamic Effects Adenosine produces a direct negative chronotropic, dromotropic and inotropic effect on the heart, presumably due to A 1 -receptor agonism, and produces peripheral vasodilation, presumably due to A 2 -receptor agonism. The net effect of adenosine injection in humans is typically a mild to moderate reduction in systolic, diastolic and mean arterial blood pressure associated with a reflex increase in heart rate. Rarely, significant hypotension and tachycardia have been observed [see Warnings and Precautions (5.4) ] .
12.3Pharmacokinetics Distribution Intravenously administered adenosine distributes from the circulation via cellular uptake, primarily by erythrocytes and vascular endothelial cells. This process involves a specific transmembrane nucleoside carrier system that is reversible, nonconcentrative, and bidirectionally symmetrical. Metabolism Intracellular adenosine is metabolized either via phosphorylation to adenosine monophosphate by adenosine kinase, or via deamination to inosine by adenosine deaminase in the cytosol.
Since adenosine kinase has a lower K m and V max than adenosine deaminase, deamination plays a significant role only when cytosolic adenosine saturates the phosphorylation pathway. Inosine formed by deamination of adenosine can leave the cell intact or can be degraded to hypoxanthine, xanthine, and ultimately uric acid. Adenosine monophosphate formed by phosphorylation of adenosine is incorporated into the high-energy phosphate pool.
Elimination While extracellular adenosine is primarily cleared from plasma by cellular uptake with a half-life of less than 10 seconds in whole blood, excessive amounts may be deaminated by an ecto-form of adenosine deaminase. Specific Populations Renal Impairment As adenosine does not require renal function for its activation or inactivation, renal impairment would not be expected to alter its effectiveness or tolerability. Hepatic Impairment As adenosine does not require hepatic function for its activation or inactivation, hepatic impairment would not be expected to alter its effectiveness or tolerability.
