Cordarone-X

Aratac

USE: Anti-arrhythmia

This medicine is used for the treatment of heart arrhythmias (irregularities), in particular when other medicines have been unsuccessful. It is known as a Class III agent, where it has broad anti-arrhythmic activity and works through prolonging the duration of electrical activity in the heart. This effect basically slows down the heart providing normal rhythm back to your heartbeat.

Amiodarone has a long half life, therefore it is usually given once daily. It is also often initiated in hospital or under specialist supervision partly due to its complexity.

Cautions:

• Thyroid disease
• Liver and kidney impairment
• Pregnancy and breastfeeding
• Severe heart failure
• Elderly

Side effects:

Metallic taste, liver and lung problems (needs monitoring), hyper/hypothyroidism, neuropathy, corneal (eye) deposits, skin discolouration (bluish), photosensitivity have been reported. Other cases reported include nausea, skin rash, vomiting and fatigue.

Interactions:

Digoxin, warfarin, beta-blockers and calcium-channel blockers should be used with caution in combination with amiodarone.
