Effect of amiodarone, an antiarrhythmic drug, on serum and liver lipids and serum marker enzymes in rats.

Administration of amiodarone (AD) to rats leads to marked damage to liver, as evidenced by pathological changes and significant increases in activities of serum marker enzymes and levels of lipids like cholesterol and phospholipids with no alteration in the triglyceride levels. The risk factor, that is the total cholesterol/HDL cholesterol ratio, exhibited increase in the experimental animals, indicating that amiodarone treatment may lead to the development of coronary heart disease.
