FOR PRACTICAL PURPOSES, QUINIDINE IS ONLY GIVEN ORALLY, ALTHOUGH IT CAN BE ADMINEITHER IM OR IV UNDER SPECIAL CIRCUMSTANCES. THE USUAL ORAL DOSE OF QUINIDINE SULFATE IS 200 TO 300 MG THREE TO FOUR TIMES A DAY. ... FOR PATIENTS WITH PREMATURE ATRIAL OR VENTRICULAR CONTRACTIONS OR MAINTENANCE THERAPY. HIGHER AND/OR MORE FREQUENT DOSES CAN BE USED FOR LIMITED PERIODS FOR TREATMENT OF PAROXYSMAL VENTRICULAR TACHYCARDIA.

Quinidine is used primarily as prophylactic therapy to maintain normal sinus rhythm after conversion of atrial fibrillation and/or flutter by other methods. The drug is also used to prevent the recurrence of paroxysmal atrial fibrillation, paroxysmal atrial tachycardia, paroxysmal atrioventricular junctional rhythm, paroxysmal ventricular tachycardia, and atrial or ventricular premature contractions.

INDIVIDUALS WITH THE LONG Q-T SYNDROME OR THOSE WHO RESPOND TO LOW CONCENTRATIONS OF QUINIDINE WITH MARKED LENGTHENING OF THE Q-T INTERVAL APPEAR TO BE PARTICULARLY AT RISK /OF SYNCOPE OR SUDDEN DEATH/ AND SHOULD NOT BE TREATED WITH THIS DRUG. /QUINIDINE/
Gilman, A.G., T.W. Rall, A.S. Nies and P. Taylor (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 8th ed. New York, NY. Pergamon Press, 1990., p. 853
EXCESSIVE CONCENTRATION OF DRUG IN PLASMA WILL CAUSE ADVERSE EFFECTS IN ANY PATIENT. BECAUSE QUINIDINE HAS LOW THERAPEUTIC RATIO, CONSTANT VIGILANCE IS THUS REQUIRED IN EVERY PATIENT TAKING THIS DRUG. /QUINIDINE/
Gilman, A.G., T.W. Rall, A.S. Nies and P. Taylor (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 8th ed. New York, NY. Pergamon Press, 1990., p. 853
Quinidine should be used with extreme caution, if at all, in patients with incomplete atrioventricular nodal block, since complete heart block and asystole may result. Im or iv administration of quinidine is especially hazardous in the presence of atrioventricular block, in the absence of atrial activity, and the patients with extensive myocardial injury. Hypokalemia, hypoxia, and disorders of acid base balance must be eliminated as potentiating factors in patients who require large doses of antiarrhythmic agents to control ventricular arrhythmias.

Adrenergic alpha-Antagonists
Drugs that bind to but do not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous adrenergic agonists. Adrenergic alpha-antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma. (See all compounds classified as Adrenergic alpha-Antagonists.)
Enzyme Inhibitors
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)
Anti-Arrhythmia Agents
Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade. (See all compounds classified as Anti-Arrhythmia Agents.)
Muscarinic Antagonists
Drugs that bind to but do not activate MUSCARINIC RECEPTORS, thereby blocking the actions of endogenous ACETYLCHOLINE or exogenous agonists. Muscarinic antagonists have widespread effects including actions on the iris and ciliary muscle of the eye, the heart and blood vessels, secretions of the respiratory tract, GI system, and salivary glands, GI motility, urinary bladder tone, and the central nervous system. (See all compounds classified as Muscarinic Antagonists.)
Antimalarials
Agents used in the treatment of malaria. They are usually classified on the basis of their action against plasmodia at different stages in their life cycle in the human. (From AMA, Drug Evaluations Annual, 1992, p1585) (See all compounds classified as Antimalarials.)
Voltage-Gated Sodium Channel Blockers
A class of drugs that inhibit the activation of VOLTAGE-GATED SODIUM CHANNELS. (See all compounds classified as Voltage-Gated Sodium Channel Blockers.)
Cytochrome P-450 CYP2D6 Inhibitors
Drugs and compounds which inhibit or antagonize the biosynthesis or actions of CYTOCHROME P-450 CYP2D6. (See all compounds classified as Cytochrome P-450 CYP2D6 Inhibitors.)

LIVER METABOLISM & RENAL EXCRETION ARE THE MAIN ROUTES OF ELIMINATION. ENTEROHEPATIC CIRCULATION WOULD NOT SIGNIFICANTLY ALTER ABSORPTION KINETICS AS REFLECTED BY BLOOD CONCENTRATION.
PMID:7264866 KOSKAS J ET AL; J PHARM BELG 36 (3): 193 (1981)
PEAK PLASMA CONCN OF 0.29 UG/ML OF QUINIDINE WERE MEASURED @ 4 HR AFTER ADMIN OF SUSTAINED RELEASE CAPSULE (250 MG QUINIDINE BISULFATE) AND DECLINED STEADILY DURING THE NEXT 8 HR, WHILE AFTER ADMIN OF SUSTAINED RELEASE TABLET (300 MG QUINIDINE SULFATE) THEY WERE FAIRLY EVEN DURING 2-10 HR AFTER DOSING. PLASMA CONCENTRATIONS WERE HIGHER AT LATER TIMES FOR THE CAPSULE THAN FOR THE TABLET. THE BIOAVAILABILITY OF QUINIDINE FROM THE CAPSULES DURING 12 HR WAS 184% COMPARED TO THE TABLET. MEAN QUINIDINE PLASMA CONCN WERE SIGNIFICANTLY GREATER @ 3, 4, 6, 8, & 10 HR AFTER ADMIN OF THE CAPSULE THAN AFTER THE TABLET.

QUINIDINE YIELDS 2'-HYDROXYQUINIDINE AS METABOLITE IN MAN. /QUINIDINE; FROM TABLE/
Goodwin, B.L. Handbook of Intermediary Metabolism of Aromatic Compounds. New York: Wiley, 1976., p. Q-3
MOST URINARY METABOLITES ARE HYDROXYLATED AT ONLY ONE SITE, EITHER ON THE QUINOLINE RING OR ON THE QUINUCLIDINE RING; SMALL AMOUNTS OF DIHYDROXY COMPOUNDS ARE ALSO FOUND. THE FRACTION OF A DOSE OF QUINIDINE THAT IS METABOLIZED & THE METABOLIC PATHWAY APPEAR TO VARY CONSIDERABLY FROM PATIENT TO PATIENT.
Gilman, A.G., T.W. Rall, A.S. Nies and P. Taylor (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 8th ed. New York, NY. Pergamon Press, 1990., p. 852
Quinidine is metabolized in the liver, principally via hydroxylation to 3-hydroxyquinidine and 2-quinidinone. The metabolites may be pharmacologically active. Approximately 10-50% of a dose is excreted in urine (probably by glomerular filtration) as unchanged drug within 24 hr. /Quinidine/
McEvoy, G.K. (ed.). American Hospital Formulary Service - Drug Information 93. Bethesda, MD: American Society of Hospital Pharmacists, Inc., 1993 (Plus Supplements, 1993)., p. 993
THE ELIMINATION HALF-LIFE OF QUINIDINE RANGES FROM 4 TO 10 HR IN HEALTHY PERSONS, WITH USUAL MEAN VALUE OF 6 TO 7 HR. HALF-LIFE IS SIGNIFICANTLY PROLONGED IN ELDERLY PERSONS, EVEN WHEN THEY ARE APPARENTLY HEALTHY. /QUINIDINE/

Quinidine generally has a plasma half-life of 6-8 hr in healthy individuals, but half-life may range from 3-16 hr or longer. In one study in patients with Plasmodium falciparum malaria, the elimination half-life of the drug averaged 12.8 hr (range: 6.6-24.8 hr). /Quinidine/
