MECHANISM OF ACTION — Active metabolite, albendazole, causes selective degeneration of cytoplasmic microtubules in intestinal and tegmental cells of intestinal helminths and larvae; glycogen is depleted, glucose uptake and cholinesterase secretion are impaired, and desecratory substances accumulate intracellulary. ATP production decreases causing energy depletion, immobilization, and worm death.
PHARMACODYNAMICS / KINETICS Absorption: <5%; may increase up to 4-5 times when administered with a fatty meal
Distribution: Well inside hydatid cysts and CSF
Protein binding: 70%
Metabolism: Hepatic; extensive first-pass effect; pathways include rapid sulfoxidation (major), hydrolysis, and oxidation
Half-life elimination: 8-12 hours
Time to peak, serum: 2-2.4 hours
Excretion: Urine (<1% as active metabolite); feces

CANADIAN BRAND NAMES — Fabrazyme®
INTERNATIONAL BRAND NAMES — Fabrazyme (AT, BE, BG, CA, CH, CZ, DE, DK, ES, FI, FR, GB, GR, HU, IE, IL, IT, NL, NO, PL, PT, RU, SE, TR)
MECHANISM OF ACTION — Agalsidase beta is a recombinant form of the enzyme alpha-galactosidase-A, which is required for the hydrolysis of GL-3 and other glycosphingolipids. The compounds may accumulate (over many years) within the tissues of patients with Fabry disease, leading to renal and cardiovascular complications. In clinical trials of limited duration, agalsidase been noted to reduce tissue inclusions of a key sphingolipid (GL-3). It is believed that long-term enzyme replacement may reduce clinical manifestations of renal failure, cardiomyopathy, and stroke. However, the relationship to a reduction in clinical manifestations has not been established.

ADMINISTRATION — For rapid bolus I.V. use only; administer I.V. push over 1-2 seconds at a peripheral I.V. site as proximal as possible to trunk (not in lower arm, hand, lower leg, or foot); follow each bolus with normal saline flush. Note: Preliminary results in adults suggest adenosine may be administered via central line at lower doses (eg, adults initial dose: 3 mg)
COMPATIBILITY — Stable in D5LR, D5W, LR, NS.
USE Adenocard®: Treatment of paroxysmal supraventricular tachycardia (PSVT) including that associated with accessory bypass tracts (Wolff-Parkinson-White syndrome); when clinically advisable, appropriate vagal maneuvers should be attempted prior to adenosine administration; not effective in atrial flutter, atrial fibrillation, or ventricular tachycardia
Adenoscan®: Pharmacologic stress agent used in myocardial perfusion thallium-201 scintigraphy
USE - UNLABELED / INVESTIGATIONAL — Adenoscan®: Acute vasodilator testing in pulmonary artery hypertension
ADVERSE REACTIONS SIGNIFICANT — Note: Frequency varies based on use; higher frequency of infusion-related effects, such as flushing and lightheadedness, were reported with continuous infusion (Adenoscan®).
>10%: Cardiovascular: Facial flushing (18% to 44%) Central nervous system: Headache (2% to 18%), lightheadedness (2% to 12%) Neuromuscular & skeletal: Discomfort of neck, throat, jaw (<1% to 15%) Respiratory: Dyspnea (12% to 28%), chest pressure/discomfort (7% to 40%)
1% to 10%: Cardiovascular: Hypotension (<1% to 2%), AV block (infusion 6%; third degree <1%), ST segment depression (3%), palpitation, chest pain Central nervous system: Dizziness, nervousness (2%), apprehension Gastrointestinal: Nausea (3%) Neuromuscular & skeletal: Upper extremity discomfort (up to 4%), numbness (up to 2%), paresthesia (up to 2%) Respiratory: Hyperventilation Miscellaneous: Diaphoresis
<1% (Limited to important or life-threatening): Asystole (prolonged), atrial fibrillation, back discomfort, bradycardia, bronchospasm, blurred vision, burning sensation, hypertension (transient), injection site reaction, intracranial pressure increased, metallic taste, pressure in groin, respiratory arrest, seizure, torsade de pointes, ventricular fibrillation, ventricular tachycardia
CONTRAINDICATIONS — Hypersensitivity to adenosine or any component of the formulation; second- or third-degree AV block or sick sinus syndrome (except in patients with a functioning artificial pacemaker), atrial flutter, atrial fibrillation, and ventricular tachycardia (this drug is not effective in converting these arrhythmias to sinus rhythm). The manufacturer states that Adenoscan® should be avoided in patients with known or suspected bronchoconstrictive or bronchospastic lung disease.
WARNINGS / PRECAUTIONS Concerns related to adverse effects: Atrial fibrillation/flutter: There have been reports of atrial fibrillation/flutter in patients with paroxysmal supraventricular tachycardia (PSVT) associated with accessory conduction pathways after adenosine. Does not convert afib/flutter to normal sinus rhythm; risk of serious arrhythmias/hypotension. Not for use in patients with afib/flutter associated with Wolff-Parkinson-White Syndrome. Conduction disturbances: Adenosine decreases conduction through the AV node and may produce first-, second-, or third-degree heart block. Patients with pre-existing S-A nodal dysfunction may experience prolonged sinus pauses after adenosine; use caution in patients with first-degree AV block or bundle branch block; avoid use of adenosine for pharmacologic stress testing in patients with high-grade AV block or sinus node dysfunction (unless a functional pacemaker is in place). Rare, prolonged episodes of asystole have been reported, with fatal outcomes in some cases. Hypotension: May produce profound vasodilation with subsequent hypotension. When used as a bolus dose (PSVT), effects are generally self-limiting (due to the short half-life of adenosine). However, when used as a continuous infusion (pharmacologic stress testing), effects may be more pronounced and persistent, corresponding to continued exposure. Use infusions with caution in patients with autonomic dysfunction, carotid stenosis (with cerebrovascular insufficiency), uncorrected hypovolemia, pericarditis, pleural effusion and/or stenotic valvular heart disease. Proarrhythmic effects: Watch for proarrhythmic effects; monitor and adjust dose to prevent QTc prolongation.
Disease-related concerns: Asthma: A limited number of patients with asthma have received adenosine and have not experienced exacerbation of their asthma. Adenosine may cause bronchoconstriction in patients with asthma; should be used cautiously in patients with obstructive lung disease not associated with bronchoconstriction (eg, emphysema, bronchitis). Electrolyte imbalance: Correct electrolyte disturbances, especially hypokalemia or hypomagnesemia, prior to use and throughout therapy.
Concurrent drug therapy issues: Caffeine: Pharmacologic stress testing: Withhold for five half-lives prior to adenosine use; avoid dietary caffeine for 12-24 hours prior to pharmacologic stress testing. Drugs which slow AV conduction: Use with caution in patients receiving other drugs which slow AV conduction (eg, digoxin, verapamil). Theophylline: Withhold for five half-lives prior to adenosine use whenever possible (eg, pharmacological stress testing).
Special populations: Elderly: Use with caution in the elderly; may be at increased risk of hemodynamic effects, bradycardia, and/or AV block.
Dosage form specific issues: Adenocard®: Transient AV block is expected. When used in PSVT, at the time of conversion to normal sinus rhythm, a variety of new rhythms may appear on the ECG. Administer as a rapid bolus, either directly into a vein or (if administered into an I.V. line), as close to the patient as possible (followed by saline flush).
Other warnings/precautions: CAST trial: In the Cardiac Arrhythmia Suppression Trial (CAST), recent (>6 days but <2 years ago) myocardial infarction patients with asymptomatic, nonlife-threatening ventricular arrhythmias did not benefit and may have been harmed by attempts to suppress the arrhythmia with flecainide or encainide. An increased mortality or nonfatal cardiac arrest rate (7.7%) was seen in the active treatment group compared with patients in the placebo group (3%). The applicability of the CAST results to other populations is unknown. Antiarrhythmic agents should be reserved for patients with life-threatening ventricular arrhythmias.
DRUG INTERACTIONS Carbamazepine may increase heart block.
Dipyridamole potentiates effects of adenosine; reduce dose of adenosine.
Theophylline and caffeine (methylxanthines) antagonize adenosine's effects; may require increased dose of adenosine.
ETHANOL / NUTRITION / HERB INTERACTIONS — Food: Avoid food or drugs with caffeine. Adenosine's therapeutic effect may be decreased if used concurrently with caffeine. Avoid dietary caffeine for 12-24 hours prior to pharmacologic stress testing.
PREGNANCY RISK FACTOR — C (show table)
PREGNANCY IMPLICATIONS — Reports of administration during pregnancy have indicated no adverse effects on fetus or newborn attributable to adenosine.
LACTATION — Excretion in breast milk unknown
DIETARY CONSIDERATIONS — Avoid dietary caffeine for 12-24 hours prior to pharmacologic stress testing.
MONITORING PARAMETERS — ECG monitoring, heart rate, blood pressure
TOXICOLOGY / OVERDOSE COMPREHENSIVE — Since the half-life of adenosine is <10 seconds, any adverse effects are rapidly self-limiting. Intoxication is usually short-lived since the half-life of the drug is very short. Treatment of prolonged effects requires individualization. Theophylline and other methylxanthines are competitive inhibitors of adenosine and may have a role in reversing its toxic effects. To reverse the effects of Adenoscan®, administer theophylline 50-125 mg slow I.V. push.
