Терапеутске индикације:

Amiodarone hydrochloride tablets are indicated for the treatment of documented, life-threatening recurrent ventricular fibrillation and life-threatening recurrent hemodynamically unstable tachycardia in adults who have not responded to adequate doses of other available antiarrhythmics or when alternative agents cannot be tolerated. - Cardiogenic shock. - Sick sinus syndrome, second- or third-degree atrioventricular block, bradycardia leading to syncope without a functioning pacemaker. - Known hypersensitivity to the drug or to any of its components, including iodine. Risk Summary Available data from postmarketing reports and published case series indicate that amiodarone use in pregnant women may increase the risk for fetal adverse effects including neonatal hypo- and hyperthyroidism, neonatal bradycardia, neurodevelopmental abnormalities, preterm birth and fetal growth restriction. Amiodarone and its metabolite, desethylamiodarone (DEA), cross the placenta. Untreated underlying arrhythmias, including ventricular arrhythmias, during pregnancy pose a risk to the mother and fetus ( see Clinical Considerations). In animal studies, administration of amiodarone to rabbits, rats, and mice during organogenesis resulted in embryo- fetal toxicity at doses less than the maximum recommended human maintenance dose (see Data) . Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%-4% and 15%-20%, respectively. Clinical Considerations Disease-associated maternal and or embryo/fetal Risk The incidence of ventricular tachycardia is increased and may be more symptomatic during pregnancy. Ventricular arrhythmias most often occur in pregnant women with underlying cardiomyopathy, congenital heart disease, valvular heart disease, or mitral valve prolapse. Most tachycardia episodes are initiated by ectopic beats and the occurrence of arrhythmia episodes may therefore, increase during pregnancy due to the increased propensity to ectopic activity. Breakthrough arrhythmias may also occur during pregnancy, as therapeutic treatment levels may be difficult to maintain due to the increased volume of distribution and increased drug metabolism inherent in the pregnant state. Fetal/Neonatal adverse reactions Amiodarone and its metabolite have been shown to cross the placenta. Adverse fetal effects associated with maternal amiodarone use during pregnancy may include neonatal bradycardia, QT prolongation, and periodic ventricular extrasystoles, neonatal hypothyroidism (with or without goiter) detected antenatally or in the newborn and reported even after a few days of exposure, neonatal hyperthyroxinemia, neurodevelopmental abnormalities independent of thyroid function, including speech delay and difficulties with written language and arithmetic, delayed motor development, and ataxia, jerk nystagmus with synchronous head titubation, fetal growth restriction, and premature birth. Monitor the newborn for signs and symptoms of thyroid disorder and cardiac arrhythmias. Labor and Delivery Risk of arrhythmias may increase during labor and delivery. Patients treated with amiodarone hydrochloride tablets should be monitored continuously during labor and delivery [see Warnings and Precautions ( 5.4)]. Data Animal Data In pregnant rats and rabbits during the period of organogenesis, amiodarone HCl in doses of 25 mg/kg/day (approximately 0.4 and 0.9 times, respectively, the maximum recommended human maintenance dose*) had no adverse effects on the fetus. In the rabbit, 75 mg/kg/day (approximately 2.7 times the maximum recommended human maintenance dose*) caused abortions in greater than 90% of the animals. In the rat, doses of 50 mg/kg/day or more were associated with slight displacement of the testes and an increased incidence of incomplete ossification of some skull and digital bones; at 100 mg/kg/day or more, fetal body weights were reduced; at 200 mg/kg/day, there was an increased incidence of fetal resorption. (These doses in the rat are approximately 0.8, 1.6 and 3.2 times the maximum recommended human maintenance dose*) Adverse effects on fetal growth and survival also were noted in one of two strains of mice at a dose of 5 mg/kg/day (approximately 0.04 times the maximum recommended human maintenance dose*). *600 mg in a 60 kg patient (doses compared on a body surface area basis) Risk Summary Amiodarone and one of its major metabolites, DEA, are present in breastmilk at between 3.5% and 45% of the maternal weight- adjusted dosage of amiodarone. There are cases of hypothyroidism and bradycardia in breastfed infants, although it is unclear if these effects are due to amiodarone exposure in breastmilk. Breastfeeding is not recommended during treatment with amiodarone hydrochloride tablets [see Warnings and Precautions ( 5.6, 5.7)] . Infertility Based on animal fertility studies, amiodarone hydrochloride tablets may reduce female and male fertility. It is not known if this effect is reversible. [see Nonclinical Toxicology ( 13.1)] . The safety and effectiveness of amiodarone hydrochloride tablets in pediatric patients have not been established. Normal subjects over 65 years of age show lower clearances and increased drug half-life than younger subjects [see Clinical Pharmacology ( 12.3)]. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

(A-mi-OH-da-rone HYE-droe-KLOR-ide) Tablets
What is the most important information I should know about amiodarone
hydrochloride tablets?
Amiodarone hydrochloride tablets can cause serious side effects that
can lead to death, including:
•
lung problems
•
liver problems
•
worsening of heartbeat problems
Call your healthcare provider or get medical help right away if you
have any of the following symptoms
during treatment with amiodarone hydrochloride tablets:
•
trouble breathing, wheezing, shortness of breath, coughing chest pain,
spitting up of blood, or
fever
•
nausea or vomiting, brown or dark-colored urine, feel more tired than

skin or the whites of your eyes (jaundice), or right upper
stomach-area pain
•
heart pounding, skipping a beat, beating fast or slowly, feel
light-headed, or if you faint
•
vision problems, including blurred vision, see halos, or your eyes
become sensitive to light. You
should have regular eye exams before and during treatment with
amiodarone hydrochloride
tablets.
Amiodarone hydrochloride tablets should be started in a hospital so
that your medical condition can be
carefully monitored.
Amiodarone hydrochloride tablets should only be used to treat people
who have been diagnosed with life-
threatening heartbeat problems called ventricular arrhythmias, when
other treatments did not work or you
cannot tolerate them.
Amiodarone hydrochloride tablets can cause other serious side effects.
See "What are the possible side
effects of amiodarone hydrochloride tablets?" If you get serious side
effects during treatment you may
need to stop amiodarone hydrochloride tablets, have your dose changed,
or get medical treatment. Talk
with your healthcare provider before you stop taking amiodarone
hydrochloride tablets.
You may still have side effects after stopping amiodarone
hydrochloride tablets because the medicine
stays in your body for months after treatment is stopped.
