Safety and Efficacy of Ibutilide in Cardioversion of Atrial Flutter And
J Am Board Fam Med: first published as 10.3122/jabfm.2011.01.080096 on 5 January 2011. Downloaded from CLINICAL REVIEW Safety and Efficacy of Ibutilide in Cardioversion of Atrial Flutter and Fibrillation Madhuri Nair, MD, Lekha K. George, MD, and Santhosh K. G. Koshy, MD This article reviews the safety and efficacy of ibutilide for use in patients with atrial fibrillation and flut- ter. Ibutilide, a class III antiarrhythmic agent, is primarily used for conversion of atrial flutter and fi- brillation and is a good alternative to electrical cardioversion. Ibutilide has a conversion rate of up to 75% to 80% in recent-onset atrial fibrillation and flutter; the conversion rate is higher for atrial flutter than for atrial fibrillation. It is also safe in the conversion of chronic atrial fibrillation/flutter among patients receiving oral amiodarone therapy. Ibutilide pretreatment facilitates transthoracic defibrilla- tion and decreases the energy requirement of electrical cardioversion by both monophasic and biphasic shocks. Pretreatment with ibutilide before electrical defibrillation has a conversion rate of 100% com- pared with 72% with no pretreatment. Ibutilide is also safe and efficient in the treatment of atrial fibril- lation in patients who have had cardiac surgery, and in accessory pathway–mediated atrial fibrillation where the conversion rate of ibutilide is as high as 95%. There is up to a 4% risk of torsade de pointes and a 4.9% risk of monomorphic ventricular tachycardia. Hence, close monitoring in an intensive care unit setting is warranted during and at least for 4 hours after drug infusion. The anticoagulation strat- egy is the same as for any other mode of cardioversion.(J Am Board Fam Med 2011;24:86–92.)

Ibutilide fumarate prolongs action potential duration in isolated adult cardiac myocytes and increases both atrial and ventricular refractoriness in vivo, i.e. class III electrophysiologic effects. Voltage clamp studies indicate that ibutilide at nanomolar concentrations, delays repolarisation by activation of a slow, inward current (predominantly sodium), rather than by blocking outward potassium currents, which is the mechanism by which most other class III antiarrhythmics act. These effects lead to prolongation of atrial and ventricular action potential duration and refractoriness, the predominant electrophysiologic properties of ibutilide in humans that are thought to be the basis for its antiarrhythmic effect. 2 PHARMACODYNAMICS Electrophysiologic Effects: Ibutilide produces mild slowing of the sinus rate and atrioventricular conduction. Ibutilide produces no clinically significant effect on QRS duration at the recommended dosage. Ibutilide produces dose-related prolongation of the QT interval, which is thought to be associated with its antiarrhythmic activity. However, there is no established relationship between plasma concentration and antiarrhythmic activity. In studies in healthy volunteers, intravenous infusions of ibutilide resulted in prolongation of the QT interval that was directly correlated with ibutilide plasma concentration during and after 10-minute and 8-hour infusions. -

The FDA background package often contains assessments and/or conclusions and recommendations written by individual FDA reviewers. Such conclusions and recommendations do not necessarily represent the final position of the individual reviewers, nor do they necessarily represent the final position of the Review Division or Office. We have brought New Drug Application 22034, atrial fibrillation for the treatment of recent onset atrial fibrillation, to this Advisory Committee in order to gain the Committee’s insights and opinions on key issues identified by the Agency. The background package may not include all issues relevant to the final regulatory recommendation, and the final determination may be affected by issues not discussed at the advisory committee meeting. The FDA will not issue a final determination on the issues at hand until input from the advisory committee process has been considered and all reviews have been finalized. 2 Table of Contents Glossary .......................................................................................................................................... 8 1.

PHARMACY TIMES by IEHP PHARMACEUTICAL SERVICES DEPARTMENT February 11, 2013
PHARMACY TIMES BY IEHP PHARMACEUTICAL SERVICES DEPARTMENT February 11, 2013 The Centers for Medicare and Medicaid Services (CMS) developed performance and quality measures to help Medicare beneficiaries make informed decisions regarding health and prescription drug plans. As part of this effort, CMS adopted measures for High Risk Medication (HRM) endorsed by the Pharmacy Quality Alliance (PQA) and the National Quality Forum (NQF). The HRM was developed using existing HEDIS measurement “Drugs to be avoided in the elderly”. The HRM rate analyzes the percentage of Medicare Part D beneficiaries 65 years or older who have received prescriptions for drugs with a high risk of serious side effects in the elderly. In order to advance patient safety, IEHP will be identifying members over 65 and currently on one of the medications identified in Table 1. Providers will be receiving a list of these members from IEHP on an ongoing basis. IEHP asks providers to review their member’s current drug regimen and safety risk and make any appropriate changes when applicable.

Methods: Human ether-à-go-go related gene (hERG), KCNQ and Kv1.2 channels were expressed in CHO cells. The delayed rectifier potassium current (IK) was recorded from dissociated hippocampal pyramidal neurons of neonatal rats. Whole-cell voltage patch clamp was used to record the voltage-activated potassium currents. Drug-containing solution was delivered using a RSC-100 Rapid Solution Changer. Results: Both DC031050 and dofetilide potently inhibited hERG currents with IC50 values of 2.3±1.0 and 17.9±1.2 nmol/L, respectively. DC031050 inhibited the IK current with an IC50 value of 2.7±1.5 μmol/L, which was >1000 times the concentration required to inhibit hERG current. DC031050 at 3 μmol/L did not significantly affect the voltage-dependence of the steady activation, steady inactivation of IK, or the rate of IK from inactivation. Intracellular application of DC031050 (5 μmol/L) was insufficient to inhibit IK. -

These patients often develop malignant arrhythmias in need of exceptional therapeutic measures in the ICU. We report a 47-year-old patient admitted to the ED 5 h after the ingestion of a large dose of amiodarone and flecainide in a suicide attempt. During their ED stay, the patient developed signs of cardiotoxicity evidenced by electrocardiogram and ventricular arrhythmias. The toxicological results showed a level of 4.8 mg/L amiodarone and 2.98 mg/L flecainide. He was successfully treated in the Citation: Bologa, C.; Lionte, C.; ED using a large dose of sodium bicarbonate and lipid emulsion therapy. After hospital admission, Popescu, A.; Sorodoc, V.; Sorodoc, L. First Case of Acute Poisoning with he remained stable, with no need for exceptional therapeutic measures such as mechanical circulatory Amiodarone and Flecainide in support, cardiac pacing or ECMO.
