Number of vials needed =[(steady state serum digoxin level (ng/ml) x weight (kg)] / 100. amiodarone: Dosing, contraindications, side effects, and pill The highly variable systemic availability of oral amiodarone may be attributed potentially to large interindividual variability in CYP3A4 activity. Amiodarone is more effective than sotalol or propafenone in preventing recurrent atrial fibrillation in patients for whom a rhythm-control strategy is chosen. Amiodarone therapy is contraindicated in patients with second- or third-degree heart block who do not have a pacemaker. (Doses <0.5 mg have been associated with paradoxical bradycardia.). Even in patients at high risk of arrhythmic death, in whom the toxicity of this drug is an acceptable risk, this drug poses major management problems that could be life-threatening in a population at risk of sudden death, so that every effort should be made to utilize alternative agents first. Although the exact mechanism by which adenosine receptor activation relaxes vascular smooth muscle is not known, there is evidence to support both inhibition of the slow inward calcium current reducing calcium uptake, and activation of adenylate cyclase through A2 receptors in smooth muscle cells.
