In the U.S., the most common type of dam is the embankment dam. These are large dams made out of soil and rock which use their weight to hold back water. To prevent water from moving through them, embankment dams also have a thick waterproof core. The Tarbela Dam in Pakistan is the worldâs largest embankment dam.
A: Amiodarone (Cordarone) is an antiarrhythmic drug used to keep the heart beating normally in patients with life-threatening heart rhythm disorders of the ventricles (lower chambers of the heart).
The drug prevents the recurrence of life-threatening ventricular arrhythmias and produces a modest reduction of sudden deaths in high-risk patients. Amiodarone is more effective than sotalol or propafenone in preventing recurrent atrial fibrillation in patients for whom a rhythm-control strategy is chosen.he major metabolite of amiodarone is desethylamiodarone (DEA), which is known to have antiarrhythmic properties. Grapefruit juice can inhibit amiodarone metabolism and lead to elevated drug levels, 3 but the impact of this interaction on the long-term efficacy and toxicity of amiodarone is not known.
