the dextrorotatory isomer of quinine, administered orally as the gluconate, polygalacturonate, or sulfate salts, or intravenously as the gluconate salt in treatment of cardiac arrhythmias. It is also administered intravenously as the gluconate salt in the treatment of life-threatening malaria caused by Plasmodium falciparum.
One of the alkaloids of cinchona, a stereoisomer of quinine (the C-9 epimer); used as an antimalarial; also used in the treatment of atrial fibrillation and flutter, and paroxysmal ventricular tachycardia.
quinidine/quin·i·dine/ (kwin´ĭ-dēn) the dextrorotatory isomer of quinine, used in the form of the gluconate, polygalacturonate, and sulfate salts in the treatment of cardiac arrhythmias; also used in the treatment of severe falciparum malaria.
A bitter alkaloid, C20H24N2O2, that is a stereoisomer of quinine, used in the form of its salts to treat malaria and certain cardiac arrhythmias.
an antiarrhythmic agent administered as a bisulfate, gluconate, or polygalacturonate or as sulfate salts.
indications It is prescribed in the treatment of atrial flutter, atrial fibrillation, premature ventricular contractions, and tachycardias.
contraindications Known hypersensitivity to this drug prohibits its use. It is contraindicated in thrombocytopenia, myasthenia gravis, and some arrhythmias, particularly those associated with heart block.
adverse effects Among the most serious adverse effects are cardiac arrhythmia, hypertension, and cinchonism. Rare but potentially fatal hypersensitivity reactions such as anaphylaxis and thrombocytopenia may occur. Diarrhea, nausea, and vomiting are common.

A cinchona alkaloid; used as an antimalarial and to treat atrial fibrillation and flutter.
quinidineA drug derived from QUININE and used to control irregularity or excessive rapidity of the heart beat by depressing the excitability of the muscle. The drug is on the WHO official list. A brand name is Kinidin Durules.
the dextrorotatory isomer of quinine, used in treatment of cardiac arrhythmias. Several salts are used, including the gluconate, sulfate and bisulfate.
