BACKGROUND
Dextromethorphan (DM) / quinidine (Q) was approved for pseudobulbar affect (PBA) treatment based on efficacy and safety trials in patients with PBA caused by amyotrophic lateral sclerosis or multiple sclerosis. The PRISM II trial evaluated DM/Q as PBA treatment in patients with stroke,
BACKGROUND
Phase 3 trials supporting dextromethorphan/quinidine (DM/Q) use as a treatment for pseudobulbar affect (PBA) were conducted in patients with amyotrophic lateral sclerosis (ALS) or multiple sclerosis (MS). The PRISM II study provides additional DM/Q experience with PBA secondary to
Disopyramide resembles quinidine electrophysiologically, but its effect on left ventricular function has not been clarified. Twelve awake dogs were instrumented for measurement of cardiac output, left ventricular pressure and its maximal first derivative (dP/dt max), and left atrial and aortic
Cryptotanshinone (CTS), a major constituent from the roots of Salvia miltiorrhiza (Danshen), is widely used in the treatment of coronary heart disease, stroke and less commonly Alzheimer's disease. Our recent study indicates that CTS is a substrate for P-glycoprotein (PgP/MDR1/ABCB1). This study has
OBJECTIVE
To compare the relative risks and benefits of several clinical strategies for managing patients with chronic atrial fibrillation.
METHODS
Five recent randomized controlled trials of warfarin in atrial fibrillation, 6 randomized controlled trials of quinidine, and 13 longitudinal studies of
A case of quinidine-induced syncope with prevailing neurological symptoms is reported in which the transient right-sided hemiparesis and fluctuating soporific state was induced by recurrent torsades de pointes ventricular tachycardias. In connection with this case, attention is paid to the
The pharmacokinetics and haemodynamics (phono- and impedance cardiography) of single oral doses of 200 mg ibopamine (SK&F 100168), 400 mg quinidine sulphate, and their combination, have been assessed in 6 healthy male volunteers. No significant differences in the mean pharmacokinetic parameters of
Pseudobulbar affect (PBA) is a common manifestation of brain pathology associated with many neurological diseases, including amyotrophic lateral sclerosis, Alzheimer's disease, stroke, multiple sclerosis, Parkinson's disease, and traumatic brain injury. PBA is defined by involuntary and
This placebo-controlled, double-blind trial compared the hemodynamic effects of sotalol and quinidine with the use of rest and exercise gated radionuclide angiography. Patients had frequent ventricular premature depolarizations (greater than or equal to 30 VPDs/hour) and depressed cardiac function
BACKGROUND
Dextromethorphan 20 mg / quinidine 10 mg (DM/Q) was approved to treat pseudobulbar affect (PBA) based on phase 3 trials conducted in participants with amyotrophic lateral sclerosis or multiple sclerosis. PRISM II evaluated DM/Q effectiveness, safety, and tolerability for PBA following
The study was undertaken to examine 84 patients mainly with coronary heart disease and various cardiac arrhythmias. Quinidine monotherapy was found to normalize heart rate depending on its baseline values: it reduced heart rate in tachycardias and increased it in bradycardia. In patients with severe
Anticoagulation for stroke prevention in atrial fibrillation (AF) is effective. Pivotal trials RE-LY, ROCKET AF, ARISTOTLE, and ENGAGE-AF TIMI 48 tested novel agents against warfarin (W). In RE-LY, an open-label trial, dabigatran 150 mg BID (D150) was superior (35%) and 110 mg BID (D110) was
Quinidine is commonly used in the treatment of atrial and ventricular arrhythmias. Such patients are at increased risk for embolic strokes and may require concurrent anticoagulation therapy. We report here the occurrence of intracranial hemorrhage as a complication of thrombocytopenia in two
The acute hemodynamic effects of intravenously administered quinidine were studied in five heart transplant recipients with an anatomically denervated heart. Quinidine, 10 mg/kg body weight, was infused over a 20 minute period, and mild wall left ventricular dynamics were measured with a new
