 Adverse Reactions

CV: Anginal symptoms. CNS: Vertigo; dizziness; headache; fever; apprehension; restlessness; confusion; syncope; excitement; delirium; hypothermia; seizures.

GI: Nausea; vomiting; diarrhea; epigastric pain. GU: Renal tubular damage; anuria. HEPA: Hepatitis. HEMA: Acute hemolysis; hemolytic anemia; thrombocytopenic purpura; agranulocytosis; hypoprothrombinemia. OTHER: Cinchonism (headache, tinnitus, nausea, diarrhea, disturbed vision, skin, CV and CNS symptoms at very high doses); hypersensitivity (rash, pruritus, flushing, sweating, facial edema, asthmatic symptoms).

Drug Mode of Action ::  

 Action Causes pH elevation in intracellular organelles of parasites; also has skeletal muscle relaxant effects and cardiovascular effects similar to those of quinidine.

Drug Interactions ::


Aluminum-containing antacids: Causes delayed or decreased quinine absorption. Anticoagulants, oral: May cause depression of hepatic enzyme system that synthesizes vitamin K-dependent clotting factors and may enhance action of oral anticoagulants. Cimetidine: May reduce quinine’s clearance and prolong its half-life in body. Digoxin: May cause increased digoxin serum concentration. Mefloquine: May cause ECG abnormalities or cardiac arrest and may increase risk of convulsions. Do not use concurrently. Delay administration 12 hr after last dose of quinine. Neuromuscular blocking agents: May potentiate neuromuscular blockade and may result in respiratory difficulties. Urinary alkalinizers: May increase quinine serum concentrations and potentiate toxicity.
