Generic: Amiodarone Hydrochloride

Form: Tablet 200mg

Indication

$4b

Administration

Potentiation of antiarrhythmic drugs. Possible increased risk of adverse effects when used with anaesthetic agents. Monitor plasma levels of amiodarone when used with HIV protease inhibitors. Cimetidine may increase serum levels of amiodarone. Concurrent use may increase serum levels of ciclosporin. May increase risk of myopathy or rhabdomyolysis when used with HMG-CoA reductase inhibitors. Rifampin may reduce the serum levels of amiodarone. Potentially Fatal: Potentiates the effect of warfarin and other anticoagulants hence dose of warfarin generally needs to be reduced approx half. Raised plasma concentrations of digoxin, phenytoin and quinidine. Additive effect with beta-blockers and calcium-channel blockers (e.g. verapamil and diltiazem).

Adult Dose

Close monitoring is recommended as amiodarone may worsen arrhythmia especially when used concurrently with other anti-arrhythmic drugs or drugs that prolong QT interval. May cause hypotension and bradycardia. May increase risk of liver toxicity. May cause visual disturbance/impairment; corneal refractive laser surgery is not recommended in patients on amiodarone treatment. May cause lung damage; monitor for pulmonary toxicity e.g. acute respiratory distress syndrome. Monitor liver functions regularly. May affect defibrillation or pacing thresholds of cardiac devices. Correct electrolyte imbalance before starting treatment. Caution when used in patients undergoing surgery. Avoid excessive sunlight exposure due to increased risk of photosensitivity. Hepatic impairment, thyroid disease, elderly. Lactation. Lactation: Excreted into breast milk; not recommended

Renal Dose

Amiodarone is a class III antiarrhythmic agent which inhibits stimulation, prolongs action potential and refractory period in myocardial tissues. It also decreases AV conduction and sinus node function. Sinus rate is reduced by 15-20%, PR and QT intervals are increased. Amiodarone can cause marked sinus bradycardia or sinus arrest and heart block. In acute IV doses, amiodarone may exert a mild negative inotropic effect.

Mode of Action

May be taken with or without food. Take consistently w/ or w/o meals. Take w/ meals if high dose or to reduce GI discomfort. Reconstitution: To make solution for 1st rapid loading infusion or supplemental infusion: Add 3 ml of amiodarone HCl concentrate (50 mg/ml) to 100 ml of dextrose 5% to give a final conc of 1.5 g/ml; for slow infusion: Add 18 ml of amiodarone HCl concentrate (50 mg/ml) to 500 ml of dextrose 5% to give a final conc of 1.8 mg/ml; for subsequent maintenance infusions, diluted solutions with conc ranging from 1-6 mg/ml may be used. Solutions with conc ?2 mg/ml should be administered via a central venous catheter.

Precaution
