Summary. Drug interactions are reported only by a few people who take Cardizem cd and Amiodarone hydrochloride together. This review analyzes the effectiveness and drug interactions between Cardizem cd and Amiodarone hydrochloride. I had an elderly patient a few nights ago that was in sustained SVT with a heart rate in the 160's. It wouldn't respond to two diltiazem boluses or a metoprolol bolus. Compare Amiodarone vs. Cardizem, which is better for uses like: A Fib, Arrythmia and PSVT. Compare head-to-head ratings, side effects, warnings, dosages, interactions and patient reviews. Patients rated Cardizem 3/5 over Amiodarone 2.4/5 in overall satisfaction. WebMD provides information about interactions between Amiodarone Oral and amiodarone-diltiazem-verapamil. 94 Crit Care & Shock 2008. Vol 11, No. 3 Diltiazem versus Amiodarone for New-Onset Atrial Arrhythmias in Non-Cardiac Post Surgical Patients: A Cohort Study After taking this medication, for over ten yrs, my A/F is no longer controlled ,so having ablation soon, but the side effects, are really awful, besides the light sensitivity, my Doctor thinks it has damaged my lungs, as I'm having frequent bouts of breath less. without any exertion. I'm confused about your question. While cardizem has some anitarrhythmic properties, it is primarily a anti-hypertensive due to its vasodilation properties and reduction of afterload. Amiodarone may interact with beta-blockers such as atenolol , propranolol , metoprolol , or certain calcium channel blockers, such as verapamil (Calan, Isoptin, Verelan, Covera-HS) or diltiazem (Cardizem, Dilacor, Tiazac), resulting in an excessively slow heart rate or a block in the conduction of the electrical impulse through the heart. I have a question about the relationship between calcium channel blockers, specifically cartia and heart failure symptoms. I take cartia, along with amiodarone for arrythmia.
