antiarrhythmic/vomiting

Dronedarone is an antiarrhythmic agent recently approved by the United States Food and Drug Administration for the reduction of cardiovascular-related hospitalizations in patients with paroxysmal or persistent atrial fibrillation or atrial flutter. The drug is a derivative of amiodarone and has been

Two groups of unanesthetized dogs, each consisting of six animals with ventricular tachycardia caused by two-stage ligation of the anterior descending branch of the left coronary artery on the day before treatment, were given continuous intravenous infusions of 0.5 mg/kg/min of either droxicainide

Cardiovascular effects of antiarrhythmic drugs and their effects on the respiratory rate were examined in conscious beagles. Disopyramide, 1.5 mg/kg i.v., increased the blood pressure and decreased the heart rate, but higher dose of 5 mg/kg i.v. increased both. Disopyramide showed no central nervous

The chemical and pharmacologic properties, pharmacokinetics, drug interactions, clinical efficacy, adverse effects, and dosage of propafenone are reviewed. Propafenone is a class IC antiarrhythmic agent that is structurally similar to the beta blockers but that has only weak beta-blocking and

Five cardiology centers conducted open-label prospective trials of meobentine sulfate, an intravenously and orally available analog of bethanidine, to assess its potential for treatment of recurrent, drug refractory ventricular tachycardia (VT) or fibrillation (VF), and complex ventricular

Encainide (MJ 9067) was given intravenously at 1, 2, or 5 mg/kg and orally at 1, 2.5, 5, or 10 mg/kg to conscious dogs 18--23 h after two-stage ligation of the left anterior descending coronary artery. Heart rate and ventricular ectopic rate were lowered in a dose-related manner by 40--70 and

Lorcainide hydrochloride or N-(4-chlorophenyl)-N-[1-(1-methyl-ethyl)-4-piperidinyl]benzeneacetamide mono-hydrochloride (R 15889) is a new anti-arrhythmic drug. Studies in dogs show that lorcainide is effective against post-infarction and ouabain-induced ventricular arrhythmias, and abolishes

We compared the effects of quinidine and three alternate antiarrhythmic drugs on serum digoxin concentration in 63 patients before and during administration of quinidine, procainamide, disopyramide, or mexiletine. Quinidine increased digoxin concentration by at least 0.5 nmol/L in 21 of 22 patients:

Ipazilide fumarate (Win 54, 177-4) is a chemically novel antiarrhythmic agent that prolongs ventricular refractoriness and possesses antiectopic activity. Subchronic (29 days) nonclinical safety evaluation of ipazilide was conducted following oral and iv administration in Sprague-Dawley rats (20-320

Using two-stage coronary ligation-, digitalis- and adrenaline-induced canine ventricular arrhythmias, antiarrhythmic effects of nicainoprol were examined in dogs, and the minimum effective plasma concentration for each arrhythmia model was determined. Nicainoprol suppressed the arrhythmias, and the

120 cases of class IC antiarrhythmic overdose, including propafenone, flecainide, ajmaline and prajmaline overdose, were evaluated with respect to clinical course, therapy and outcome. Whereas drug overdose in general has an overall mortality of less than 1%, intoxication with antiarrhythmic drugs

BACKGROUND Intravenous (IV) amiodarone has proven efficacy in adults. However, its use in children is based on limited retrospective data. RESULTS A double-blind, randomized, multicenter, dose-response study of the safety and efficacy of IV amiodarone was conducted in 61 children (30 days to 14.9

The efficacy, pharmacokinetics, safety, and tolerability of E 047/1, an amiodarone derivative, were evaluated in patients with acute supraventricular or ventricular arrhythmia. In an open, nonrandomized prospective multicenter trial, 20 patients were treated with three different i.v. dosage regimens

In the armamentarium for rhythm control, amiodarone has been a mainstay of therapy for the management of atrial fibrillation (AF). Although amiodarone has shown to be effective in maintaining sinus rhythm, it has many extracardiac adverse effects. Dronedarone, a benzofuran amiodarone derivative, is

In a blind cross-over study, 12 patients with ventricular arrhythmias (VPC's; Lown Grades II-IVB) resistant to a daily dose of quinidine 1.2 g, disopyramide 0.8 g, N-propyl-ajmaline 0.1 g were randomly given, each dose for one week, placebo (PL), mexiletine (MEX; 400, 600, 800 mg daily) and
