Non-vitamin K antagonist oral anticoagulants with amiodarone, P-glycoprotein inhibitors, or polypharmacy in patients with atrial fibrillation: Systematic review and meta-analysis. Amiodarone, which inhibits CYP2C9 and P-glycoprotein, is commonly prescribed with non-vitamin K antagonist oral anticoagulants (NOACs) and polypharmacy in high-risk atrial fibrillation (AF) patients. We studied efficacy and safety of NOACs in AF patients receiving amiodarone, P-glycoprotein inhibitor (...) , or polypharmacy.After a systematic database search (Medline, EMBASE, CENTRAL, SCOPUS, and Web of Science), four phase-III randomized trials comparing NOACs and warfarin in "with/without amiodarone," "with/without P-glycoprotein inhibitors," or "with/without multiple (≥5, polypharmacy) concomitant drugs" subgroups were included. The outcomes were pooled using a random-effects model to determine the relative risks (RRs) for stroke/systemic thromboembolism (SSTE), major bleeding (MB), intracranial hemorrhage (ICH
Meta-Analysis Comparing the Relative Risk of Adverse Events for Amiodarone Versus Placebo Amiodarone has been associated with adverse events that may restrict its use. We performed a meta-analysis of placebo-controlled trials to assess the relative risk of adverse events of amiodarone compared with placebo. In total, 43 randomized trials were included. A total of 11,395 patients were included (5,792 patients randomized to amiodarone and 5,603 patients randomized to placebo). The incident rate (...) of adverse events per 10,000 person-years was higher in the amiodarone group compared with placebo for pulmonary (129 vs 74; relative risk (RR) 1.77, p = 0.002), thyroid (201 vs 42; RR 4.44, p <0.001), hepatic (54 vs 25; RR 2.27, p = 0.01), cardiac (771 vs 450; RR 1.94, p <0.001), neurological (140 vs 76; RR 1.93, p <0.001), and skin (81 vs 23; RR 1.99, p = 0.04) adverse events. Low-dose amiodarone was not associated with statistically significant increase in pulmonary adverse events but was still
Pre- and post-treatment with amiodarone for elective electrical cardioversion of atrial fibrillation: a systematic review and meta-analysis. Clinicians frequently pre-treat patients with amiodarone to increase the efficacy of electrical cardioversion for atrial fibrillation (AF). Our objective was to determine the precise effects of amiodarone pre- and post-treatment on conversion efficacy and sinus rhythm maintenance.We conducted a systematic review and meta-analysis of trials comparing pre (...) - and post-treatment for electrical cardioversion with amiodarone vs. no therapy on (i) acute restoration and (ii) maintenance of sinus rhythm after 1 year. We searched MEDLINE and EMBASE from inception to July 2018 for randomized controlled trials. We evaluated the risk of bias for individual studies with the Cochrane tool and overall quality of evidence with the GRADE framework. We identified eight eligible studies (n = 1012). Five studies were deemed to have unclear or high risk of selection bias. We

Phlebitis in Intravenous Amiodarone Administration: Incidence and Contributing Factors. Intravenous amiodarone is the gold-standard treatment for arrhythmias, but phlebitis is a common adverse effect.To determine the incidence and contributing factors of amiodarone-induced phlebitis and examine phlebitis severity.A systematic review was conducted of articles published before February 2016 in the Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, MEDLINE, Embase, Web (...) of Science, and gray databases (Bielefeld, Lenus, EUGrey, RIAN, and DART). All studies in which amiodarone-induced phlebitis was a primary or secondary outcome were included. Meta-analysis was not appropriate because of study heterogeneity. Studies of the same contributing factors were analyzed together.In the 20 included studies, phlebitis incidence ranged from 0% to 85%. Increasing the infusion concentration from 1.2 mg/mL to 1.8 mg/mL increased the phlebitis rate (P < .001). Total amiodarone doses

Clinical Safety and Efficacy of Wenxin Keli-Amiodarone Combination on Heart Failure Complicated by Ventricular Arrhythmia: A Systematic Review and Meta-analysis Objectives: To evaluate possible adverse effects and efficacy of Wenxin keli (WXKL)-amiodarone combination on heart failure complicated by ventricular arrhythmia. Methods: Nine electronic literature databases (the Cochrane Library, PubMed, EMBASE, IPA, AMED, CBM, CNKI, VIP, and WanFang) were searched up to February 2018. Two authors (...) extracted data and assessed risk of bias of the included studies independently. Randomized controlled trials (RCTs) and quasi-RCTs about WXKL-amiodarone combination and amiodarone alone were eligible for comparison. Results: Thirteen trials involving 1,126 patients were included. Risk of bias was assessed as high in three studies and unclear in the remaining 10 studies. Six trials reported adverse events (AE). There was no obvious difference between WXKL-amiodarone combination group and amiodarone group
Amiodarone: Wonder Drug or Wonder Why? Emergency Medicine > Journal Club > Archive > January 2018 Toggle navigation January 2018 Amiodarone: Wonder Drug or Wonder Why? Vignette Working in TCC can be draining, and on one particularly busy afternoon, you begin to suspect your own sanity. After back-to-back cardiac arrest patients, you wonder if perhaps you should have done something less stressful with your life, like maybe become a lobster boat captain or an ice road trucker. Your first code (...) is a middle-aged female who suffered cardiac arrest while watching Alabama beat Clemson during the Sugar Bowl (yeah...that's right!!!). She was initially noted to be in ventricular fibrillation (VF), and remained so after three rounds of defibrillation. As she arrives in the trauma room, you immediately continue CPR and set up to shock her again. Your attending orders amiodarone, and even though you remember hearing that this may not be very effective, you realize it's not the time to argue. The patient
Efficacy of amiodarone and lidocaine for preventing ventricular fibrillation after aortic cross-clamp release in open heart surgery: a meta-analysis of randomized controlled trials. The relative preventative efficacy of amiodarone and lidocaine for ventricular fibrillation (VF) after release of an aortic cross-clamp (ACC) during open heart surgery has not been determined. This meta-analysis was designed to systematically evaluate the influence of amiodarone, lidocaine, or placebo (...) on the incidence of VF after ACC.Prospective randomized controlled trials (RCTs) that compared the VF-preventative effects of amiodarone with lidocaine, or amiodarone or lidocaine with placebo were included. PubMed, EMBASE, and the Cochrane Library were searched for relevant RCTs. Fixed or randomized effect models were applied according to the heterogeneity of the data from the selected studies.We included eight RCTs in the analysis. Pooled results suggested that the preventative effects of amiodarone
Efficacy and Safety Outcomes of Direct Oral Anticoagulants and Amiodarone in Patients with Atrial Fibrillation. Direct oral anticoagulants (DOACs) and amiodarone are widely used in the treatment of nonvalvular atrial fibrillation. The DOACs are P-glycoprotein (P-gp) and cytochrome p-450 (CYP3A4) substrates. Direct oral anticoagulant levels may be increased by the concomitant use of potent dual P-gp/CYP3A4 inhibitors, such as amiodarone, which can potentially translate into adverse clinical (...) risk in patients with concomitant use of amiodarone. Risk ratio (RR) 95% confidence intervals were measured using the Mantel-Haenszel method. The fixed effects model was used owing to heterogeneity (I2) < 25%.Four trials with a total of 71,683 patients were analyzed, from which 5% of patients (n = 3212) were concomitantly taking DOAC and amiodarone. We found no statistically significant difference for any of the clinical outcomes (stroke or systemic embolism [RR 0.85; 95% CI, 0.67-1.06], major
Meta-analysis of the efficacies of amiodarone and nifekalant in shock-resistant ventricular fibrillation and pulseless ventricular tachycardia. Amiodarone (AMD) and nifekalant (NIF) are used in the treatment of ventricular fibrillation or tachycardia; however, only few studies have been conducted on their efficacies. Therefore, a meta-analysis was conducted. Relevant sources were identified from PubMed, Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi. The outcomes were
Amiodarone, lidocaine, magnesium or placebo in shock refractory ventricular arrhythmia: A Bayesian network meta-analysis. Recent evidence challenges, the superiority of amiodarone, compared to other anti-arrhythmic medications, as the agent of choice in pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF). We conducted Bayesian network and traditional meta-analyses to investigate the relative efficacies of amiodarone, lidocaine, magnesium (MgSO4) and placebo as treatments (...) ranking curve (SUCRA). Bayesian analysis demonstrated that lidocaine had superior effects on survival to hospital discharge, compared to amiodarone (OR, 2.18, 95% Cr.I 1.26-3.13), MgSO4 (OR, 2.03, 95% Cr.I 0.74-4.82) and placebo (OR, 2.42, 95% Cr.I 1.39-3.54). There were no statistical differences among treatment groups regarding survival to hospital admission/24 h (hrs) and return of spontaneous circulation (ROSC). Probability analysis revealed that lidocaine was the most effective therapy
Acute liver failure with amiodarone infusion: A case report and systematic review. Amiodarone, a commonly used class III antiarrhythmic agent notable for a relatively long half-life of up to 6 months and its pronounced adverse effect profile, is used for both acute and chronic management of cardiac arrhythmias. Chronic use of amiodarone has been associated with asymptomatic hepatotoxicity; however, acute toxicity is thought to be uncommon. There are only six reported cases of acute liver (...) failure (ALF) secondary to amiodarone. In all these cases the outcome of death during the same hospitalization resulted. We aimed to report the only case of acute liver failure secondary to amiodarone infusion in the existing literature where the patient survived.A 79-year-old woman admitted with atrial flutter was being treated with intravenous (IV) amiodarone when she abruptly developed coagulopathy, altered mental status and liver enzyme derangement. She was diagnosed with acute liver failure (ALF
Antiarrhythmic effects of ranolazine used both alone for prevention of atrial fibrillation and as an add-on to intravenous amiodarone for its pharmacological cardioversion: a meta-analysis. Recent evidence from relatively small randomized controlled trials would seem to support a useful role of ranolazine for the prevention and treatment of atrial fibrillation (AF). The present study is aimed at providing information about the possible beneficial anti-arrhythmic properties of ranolazine (...) analysis showed a more pronounced preventive effect of ranolazine against AF in the postoperative setting of coronary artery bypass grafting (CABG) surgery (RR=0.39; 95% CI: 0.18-0.83; P=0.02) when compared to non-postoperative AF (RR=0.76; 95% CI: 0.63-0.92; P=0.04). Ranolazine enhanced the chances of successful cardioversion when added to intravenous amiodarone compared to amiodarone alone (RR 1.18; 95% CI: 1.05-1.33; P=0.004) and significantly decreased the time to cardioversion (SMD= -10.35 h; 95
In Patients With Cardiac Arrest, Does Amiodarone or Lidocaine Increase Meaningful Survival? TAKE-HOME MESSAGE Among out-of-hospital cardiac arrest patients with shock-refractory ventricular tachycardia or ventricular ?brillation, neither amiodarone nor lidocaine increases survival to hospital discharge or good neurologic outcome.

Pre-cardiac transplant amiodarone use is not associated with postoperative mortality: An updated meta-analysis. Amiodarone remains the preferred agent for the treatment and prevention of life-threatening ventricular arrhythmias in patients with end-stage heart failure. While several reports suggest that pre-operative amiodarone exposure worsens outcomes in heart transplant recipients, other studies have failed to validate this relationship. We sought to clarify this issue by performing a meta (...) -analysis of the available literature surrounding this topic.We searched Medline, SCOPUS and the Cochrane Central Register of Controlled Trials through December 15th 2016, as well as proceedings from related conferences over the prior 3years. Included studies evaluated patients undergoing cardiac transplantation who had received pre-transplant amiodarone and reported postoperative mortality. Outcomes were pooled using a Hartung-Knapp random-effects model producing odds ratios (OR) and 95% confidence
Amiodarone: A potential risk factor for retinal phototoxicity To report the only known case, to our knowledge, of amiodarone induced retinal phototoxicity following vitrectomy surgery.A 66-year-old male presented with visual acuity of 20/150 OS secondary to an epiretinal membrane (ERM). Patient was on oral amiodarone for atrial fibrillation. Baseline spectral domain optical coherence tomography (SD-OCT) revealed an ERM with retinal thickening and schisis. The patient underwent an uncomplicated (...) showed resolution of macular edema, retinal pigment epithelium hyperplasia and an indistinct ellipsoid layer. Fluorescein angiography did not show any neovascularization. At three month follow-up, patient's vision, exam and OCT findings remained unchanged.Many pharmacologic agents have the ability to alter a patient's sensitivity to solar or artificial radiation. Drugs act as photosensitizers that lead to photochemical damage. Amiodarone has been reported to have such photosensitizing properties
