Side Effects: CNS: INTRACRANIAL HEMORRHAGE, EENT: epistaxis, gingival bleeding
Resp: bronchospasm, hemoptysis, CV: reperfusion arrhythmias, hypotension, RECURRENT ISCHEMIA/THROMBOEMBOLISM, GI: GI BLEEDING, nausea, RETROPERITONEAL BLEEDING, vomiting, GU: GU TRACT BLEEDING Derm: ecchymoses, flushing, urticarial, Hemat: BLEEDING Misc: ALLERGIC REACTIONS INCLUDING ANAPHYLAXIS, fever

Generic Name: Amiodarone Trade Name: Cordarone, Nexterone, Pacerone Classification: antiarrhythmics (class III)
MOA: Prolongs action potential and refractory period. Inhibits adrenergic stimulation. Slows the sinus rate, increases PR and QT intervals, and decreases peripheral vascular resistance (vasodilation).
Uses of Medication: PO: Management of supraventricular tachyarrhythmias. IV: management of ventricular fibrillation (VF)/pulseless ventricular tachycardia (VT) after cardiopulmonary resuscitation and defibrillation have failed; also for other life-threatening tachyarrhythmias.

Resp: ADULT RESPIRATORY DISTRESS SYNDROME (ARDS), PULMONARY FIBROSIS, PULMONARY TOXICITY CV: CHF, WORSENING OF ARRHYTHMIAS, bradycardia, hypotension GI: ↑ liver enzymes
Contraindications/Precautions: Bradycardia episodes whis cause syncope, Cardiogenic shock, Hypersensitivity to med or iodine, 2nd/3rd AV block, sinus bradycardia, sinus node dysfunction
Usual Dosage(s): PO: (Adults) 800–1600 mg/day in 1–2 doses for 1–3 wk, then 600–800 mg/day in 1–2 doses for 1 mo, then 400 mg/day maintenance dose.IV: (Adults) 150 mg over 10 min, followed by 360 mg over the next 6 hr and then 540 mg over the next 18 hr.

Patient Teaching Instruct patient to take amiodarone as directed, Advise patient to avoid drinking grapefruit juice during therapy. Teach patients to monitor pulse daily and report abnormalities. Instruct male patients to notify health care professional if signs of epididymitis, • Emphasize the importance of follow-up exams, including chest x-ray and pulmonary function tests every 3–6 mo and ophthalmic exams after 6 mo of therapy, and then annually
