Many trials of antiarrhythmic therapy for non-life threatening arrhythmias, has resulted in increased mortality; the risk of active therapy is probably greatest in patients with structural heart disease. In the case of quinidine used to prevent or defer recurrence of atrial flutter/fibrillation, meta-analysis data has shown that the mortality associated with the use of quinidine was more than three times greater than placebo. Another meta-analysis showed that in patients with various non-life-threatening ventricular arrhythmias, the mortality associated with the use of quinidine was consistently greater than that associated with the use of any of a variety of alternative antiarrhythmics.
Oral route (Tablet)
Active antiarrhythmic therapy has resulted in increased mortality; the risk of active therapy is probably greatest in patients with structural heart disease. In a meta-analysis, the mortality associated with the use of quinidine was more than 3 times as great as the mortality associated with the use of placebo. Another meta-analysis showed that in patients with various non-life-threatening ventricular arrhythmias, the mortality associated with the use of quinidine was consistently greater than that associated with the use of alternative antiarrhythmics.
Oral route (Tablet, Extended Release)
Active antiarrhythmic therapy has resulted in increased mortality; the risk is probably greatest in patients with structural heart disease.
Serious side effects
Along with its needed effects, quinidine (the active ingredient contained in Quinaglute Dura-Tabs) may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Check with your doctor immediately if any of the following side effects occur while taking quinidine:
- Abdominal pain and/or yellow eyes or skin
- blurred and/or double vision, confusion, delirium, disturbed color perception, headache, noises or ringing in the ear, and/or visual intolerance of light
- dizziness or lightheadedness
- Chest pain, fever, general discomfort, joint pain, joint swelling, muscle pain, and/or skin rash
- nosebleeds or bleeding gums
- unusual tiredness or weakness and/or pale skin
Other side effects
Some side effects of quinidine may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects.
Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:
For Healthcare Professionals
Applies to quinidine: compounding powder, injectable solution, oral tablet, oral tablet extended release.
Quinidine side effects have varied from vague neurological and gastrointestinal complaints to myocardial toxicity. The most frequently reported symptoms have been diarrhea, nausea, and vomiting. The risk of toxicity is greater when plasma quinidine (the active ingredient contained in Quinaglute Dura-Tabs) concentrations exceed 4 mg/L.
Dose-related cinchonism may be the first sign of quinidine toxicity. Cinchonism refers to a syndrome caused by any of the cinchona alkaloids, including quinidine. It most often is a sign of chronic toxicity, but may occur after a single moderate dose in sensitive patients.[Ref]
Cinchonism may be classified as mild, moderate, or severe depending on symptoms. Mild cinchonism includes symptoms of blurred vision, transient deafness, anorexia, nausea, weakness, vertigo, tinnitus, diarrhea, and headache. Mild cinchonism does not always occur with higher dosages, nor does it preclude further quinidine therapy. Moderate cinchonism includes vomiting, hypotension, a 25% to 50% increase in QRS duration, and rare premature ventricular contractions. Severe cinchonism is characterized by myocardial toxicity such as malignant arrhythmias, QRS duration greater than 50%, high degree AV heart block, or cardiac arrest.[Ref]
Cardiovascular side effects have included hypotension, syncope, increased QRS duration (500 to 600 msec), and myocardial toxicity. Tachyarrhythmia has occurred in approximately 2% of patients. Quinidine-induced long QT syndrome has resulted in rare cases of torsades de pointes.
Myocardial toxicity may present as malignant arrhythmias, increased QRS duration of greater than 50%, high degree AV heart block, or cardiac arrest. Quinidine (the active ingredient contained in Quinaglute Dura-Tabs) may significantly decrease stroke volume and cardiac output.
The use of quinidine to prevent atrial fibrillation in patients with chronic atrial fibrillation is somewhat controversial. A large, randomized, controlled study comparing quinidine to placebo has shown no difference in efficacy and no demonstrable reduction in overall mortality in treated patients. The crude mortality rate was greater in patients treated with quinidine relative to patients treated with placebo.[Ref]
A 76-year-old man developed progressive dysphagia to solids during quinidine (the active ingredient contained in Quinaglute Dura-Tabs) therapy. Upper endoscopy revealed a proximal narrowing, but no findings of cancer or infection. Quinidine pill esophagitis was suspected and the drug was discontinued. The lesion resolved one month later and did not recur.[Ref]
Gastrointestinal side effects have been the most frequently reported adverse effects. Anorexia, nausea, vomiting, and diarrhea occurred in up to 30% of patients. Quinidine pill esophagitis has been reported. Nausea, vomiting, and diarrhea may be part of the cinchonism syndrome resulting from dose-related quinidine toxicity.[Ref]
Nervous system side effects have included dizziness, headache, tremor, nervousness and coordination difficulties. Such symptoms may be part of the cinchonism syndrome and signs of quinidine (the active ingredient contained in Quinaglute Dura-Tabs) toxicity. The anticholinergic activity of quinidine may exacerbate myasthenia gravis. Convulsions have been reported, but the association with quinidine has not been clearly defined.[Ref]
An 85-year-old man with atrial flutter developed drowsiness, emesis, and icterus associated with elevated liver function tests and marked centrilobular cholestasis with mild bile duct inflammation per liver biopsy within ten days after beginning quinidine (the active ingredient contained in Quinaglute Dura-Tabs) therapy. There was no evidence of biliary obstruction per ultrasound. The signs and symptoms of hepatitis resolved after discontinuation of quinidine.
A 58-year-old man with paroxysmal atrial fibrillation developed fever, lethargy, nausea, and abdominal pain associated with elevated liver function tests and no serological evidence of a viral etiology within ten days after beginning quinidine therapy. No liver biopsy was performed. The signs and symptoms of hepatitis began to resolve within three days after discontinuation of quinidine.
Rare cases of reversible granulomatous hepatitis, presenting as fever, urticarial rash, elevated liver function tests, and mild thrombocytopenia have been associated with quinidine. In a long-term study of 15 patients with a history of quinidine-associated hepatitis, no persistent liver function abnormalities were observed.[Ref]
Hepatic toxicity associated with quinidine is believed primarily due to hypersensitivity to quinidine. Hypersensitivity-induced hepatitis has occurred in approximately 2% of patients, usually within the first two weeks of therapy. Jaundice occurred rarely. Resolution was complete in most cases within 4 to 8 weeks following discontinuation. Not all cases have resolved. Granulomatous hepatitis has been reported.[Ref]
Ocular side effects have included mydriasis, color perception changes, night blindness, scotomata, optic neuritis, and visual field loss. Blurred vision, diplopia, and photophobia may be part of the dose-related cinchonism syndrome. Quinidine (the active ingredient contained in Quinaglute Dura-Tabs) keratopathy, an extremely rare ocular side effect, has been reported.[Ref]
A 66-year-old man with coronary artery disease developed photophobia and blurred vision while taking quinidine, metoprolol, furosemide, isosorbide, and digoxin. Slit-lamp examination revealed superficial granular deposits within the corneal epithelium; the epithelial surface was smooth and did not contain fluorescein upon staining. The corneal deposits disappeared within two months after discontinuing quinidine.[Ref]
Cases of an IgG antibody requiring the presence of quinidine, with activity against leukocytes and platelets have been reported. In some cases, significant infection or hemorrhage resulted.
A 60-year-old man developed malaise, weakness, chills, and oral ulcerations within three days of beginning quinidine and digoxin for atrial fibrillation. Laboratory examination revealed a profoundly low leukocyte count and bone marrow aspiration revealed a hypocellular myeloid line. The neutrophil count returned to baseline within three days after discontinuation of quinidine and continuation of digoxin. The authors found eight other such cases in a review of medical literature.[Ref]
Hypersensitivity-induced hepatitis has occurred in approximately 2% of patients, usually within the first two weeks of therapy. Hypersensitivity reactions including of uveitis, allergic vasculitis, lymphadenopathy, hemolytic anemia, thrombocytopenia, agranulocytosis, bronchospasm, pneumonitis and photosensitive dermatitis psoriaform rash, angioedema, sicca syndrome, arthralgia, myalgia, and elevated levels of skeletal muscle enzymes have been reported.[Ref]
A 52-year-old man developed malaise, an extensive maculopapular rash, palpable purpura, mental status changes, rigors, nausea, and night sweats during therapy with quinidine and digoxin. Laboratory findings included proteinuria, elevated liver function tests, eosinophilia, an elevated antinuclear antibody titer, and renal biopsy findings consistent with allergic granulomatous angiitis. The syndrome worsened following quinidine discontinuation, but resolved gradually with steroid therapy. Because allergic reactions to digoxin are rare, the authors implicated quinidine. Rechallenge was not performed.
A 54-year-old man with a history of atrial fibrillation, treated with digoxin and quinidine sulfate, developed fever and malaise associated with nodular infiltrates on chest X-ray. His condition worsened despite treatment with an oral cephalosporin. A diagnostic evaluation ruled out heart failure; tests for typical and atypical infections were negative. Pulmonary function testing revealed mild restriction. Two days after stopping quinidine the signs and symptoms of pneumonitis resolved. Bronchoalveolar lavage and transbronchial biopsy revealed changes consistent with allergic pneumonitis. Rechallenge with quinidine resulted in recurrent signs and symptoms of allergic pneumonitis.[Ref]
A 57-year-old man with premature ventricular depolarizations developed a papular rash on his back and chest. Resolution was complete within four weeks of discontinuation of therapy. The patient was on no other oral medications.
An 83-year-old man developed a bluish-grey discoloration involving his skin, oral mucosa, and nailbeds which resolved over four months following discontinuation of quinidine (the active ingredient contained in Quinaglute Dura-Tabs) Other medications were continued.
A 64-year-old man with a history of convalescent psoriasis vulgaris experienced an exacerbation of psoriasis within 72 hours after initiating quinidine therapy. The psoriasis was refractory to aggressive PUVA therapy and resolved only when quinidine was discontinued.[Ref]
Dermatologic side effects including photosensitive rashes, psoriasis, abnormal pigmentation, and actinic dermatitis have been reported. Quinidine has been identified as a possible cause of lichen planus in susceptible patients.[Ref]
Immunologic side effects including systemic lupus erythematosus have been rarely associated with quinidine (the active ingredient contained in Quinaglute Dura-Tabs) therapy. Rare cases of quinidine-induced polyarthropathy without development of antinuclear antibodies have been reported.[Ref]
Approximately 30 cases of quinidine-induced systemic lupus erythematosus have been reported. The majority of patients were Caucasian and elderly, without gender difference. The most frequent complaint was polyarthralgias (87%).[Ref]
Renal side effects have been limited to rare reports of quinidine-induced nephrotic syndromes.[Ref]
A 64-year-old woman developed edema, proteinuria (3 grams per 24 hours), hypercholesterolemia, elevated complement levels, and elevated antinuclear antibody titers within three months after beginning digoxin and quinidine. Signs of the nephrotic syndrome resolved within seven days after discontinuation of quinidine, but continuation of digoxin. Rechallenge with quinidine resulted in fatigue, myalgias, arthralgias, anorexia, and weakness. The author believed this case represented quinidine-induced nephrotic syndrome or a quinidine-induced lupus erythematosus-like illness complicated by renal disease.
A 63-year-old man receiving allopurinol for gout developed progressive uremia, proteinuria, edema, and purpura after beginning quinidine therapy. The patient required hemodialysis secondary to biopsy-proven, rapidly progressive glomerulonephritis. A macrophage migration-inhibition test was negative in the presence of both quinidine and allopurinol. Such tests may be falsely negative in the presence of uremia. The authors believed quinidine caused Henoch-Schonlein purpura in this patient based on a chronologic association and lack of allopurinol-associated problems following chronic therapy.[Ref]
Psychiatric side effects of depression have been associated with quinidine (the active ingredient contained in Quinaglute Dura-Tabs) Rare cases of acute psychosis and psychomotor agitation have been reported with subtherapeutic quinidine levels in elderly patients.[Ref]
A 73-year-old man with supraventricular tachycardia developed visual hallucinations, delusions, and psychomotor agitation within 90 minutes of the initial dose of quinidine. A serum quinidine level at the time was 0.8 mg/L (therapeutic 3 to 6 mg/L). The patient's mental status returned to baseline after discontinuation of quinidine.
A 67-year-old man with a supraventricular arrhythmia and hypertension developed psychosis and psychomotor hyperactivity within two hours after starting quinidine. A serum quinidine level at the time was 1 mg/L (therapeutic 3 to 6 mg/L). The patient's mental status returned to baseline after discontinuation of quinidine.[Ref]
Musculoskeletal effects including a case of profound musculoskeletal weakness has been reported.[Ref]
A 68-year-old woman with paroxysmal atrial fibrillation developed progressive proximal limb muscle weakness within two weeks after starting quinidine. Symptoms resolved upon discontinuation of therapy. Rechallenge was associated with recurrent weakness and a diffuse, pruritic rash. A diagnostic evaluation failed to reveal evidence of myasthenia gravis.[Ref]
