BACKGROUND
Pseudobulbar affect (PBA) is associated with neurological disorders or injury affecting the brain, and characterized by frequent, uncontrollable episodes of crying and/or laughing that are exaggerated or unrelated to the patient's emotional state. Clinical trials establishing
The serum digoxin concentration increased in 25 of 27 study patients (93%), and the mean serum digoxin concentration rose from 1.4 ng/ml to 3.2 ng/ml during quinidine therapy. Anorexia, nausea, or vomiting developed in 16 patients (59%) but disappeared in all ten patients for whom the digoxin dose
Although quinidine has been widely used since the beginning of the century, quinidine-induced hepatotoxicity has been recently reported in the literature. We describe a reversible case of quinidine-induced hepatotoxicity. A 62-y-old male with a past medical history of atrial flutter and adult onset
Acute iridocyclitis is a rare hypersensitive reaction to quinidine treatment. The third case in the literature is reported here. A woman aged 80 years developed pyrexia, anorexia, nausea, skin rash and hepatic dysfunction after treatment with quinidine for two weeks. Four weeks later, while still
Quinidine gluconate (total dose 4-4 to 9-1 mg/kg) was infused intravenously over 22 minutes in 20 patients with either frequent premature ventricular contractions or supraventricular arrhythmias, 16 of whom had bundle-branch block. Therapeutic plasma quinidine levels (3 to 7 mg/l) were achieved in
Thirty-one patients were entered into a pilot study combining oral quinidine with epirubicin 100 mg m-2 as first line chemotherapy in advanced breast cancer. Three patients were treated with quinidine 1 g b.d., and developed symptoms of toxicity. Of eight subsequent patients treated with quinidine
BACKGROUND
Pain associated with diabetic peripheral neuropathy (DPN) has a substantial negative impact on patients' quality of life.
OBJECTIVE
The primary objective of this study was to evaluate the tolerability of capsules containing dextromethorphan (DM) and quinidine (Q) in patients with painful
The authors report the case of a 63 year-old woman who developed high-grade fever with chills, nausea, diarrhea, severe pain in the right hypochondrium, and jaundice after one month's treatment with 300 mg of hydroquinidine hydrochloride daily. Serum bilirubin and aminotransferases were slightly
Following the development of digoxin radioimmunoassay, we noted that serum digoxin concentrations appeared to rise in patients given quinidine. To further evaluate this important possible interaction between digoxin and quinidine, charts from 863 cardiology patients were reviewed. Ninety two
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:
Quinidine is known to inhibit p-glycoprotein and enhance the activity of vinblastine against cultured renal carcinoma cells. We have combined quinidine and vinblastine in a Phase I trial in patients with metastatic renal cell carcinoma. Twenty-three patients were entered. Prior treatment included
The antiarrhythmic efficacy and safety of oral flecainide acetate and quinidine sulfate were compared in a double-blind, 16-center parallel trial involving 280 patients with chronic premature ventricular complexes (PVCs). Eighty-five percent of the flecainide patients had at least 80% suppression of
Indecainide, a new type Ic antiarrhythmic agent, and quinidine sulfate were compared in a randomized double-blind parallel study. Cardiac patients with greater than or equal to 30 ventricular premature complexes per hour hour received indecainide, 50 mg, or quinidine, 200 mg every 6 hours, and the
BACKGROUND
Dextromethorphan is an over-the-counter antitussive agent that may be a rapidly acting treatment for bipolar depression. Like ketamine, it is an NMDA receptor antagonist.
METHODS
We conducted a retrospective chart review of depressed patients with treatment resistant bipolar II or bipolar
BACKGROUND
Postoperative nausea and vomiting (PONV) is a common complication after anesthesia and surgery. Ondansetron is one of the most widely used drugs in the prophylaxis of PONV and is extensively metabolized in humans. In vitro metabolism studies have shown that ondansetron is a substrate for
