Quinine disposition was studied in 5 subjects before and during an experimentally induced infection with a chloroquine-resistant strain of Plasmodium falciparum and in 2 individuals before and during artificially induced fever. Plasma quinine levels were determined by both a benzene extraction
The effects of quinine and paracetamol on fever were studied in 21 adult patients with acute uncomplicated falciparum malaria. Quinine alone (n = 7) had no significant effect on fever, whereas paracetamol given 2 h after quinine (n = 7) or 2 h before quinine (n = 7) reduced temperature by a mean of
The pharmacokinetics of quinine and its diastereoisomer quinidine has been investigated in normal and febrile rats. Endotoxin-induced fever in rats resulted in an increased quinine clearance (CL) (4.49 +/- 1.45 vs 1.38 +/- 0.65 L h-1 kg-1, P less than 0.001) and volume of distribution (Vd) (42.6 +/-
BACKGROUND
The naturally occurring alkaloid drug, quinine is commonly used for the treatment of severe malaria. Despite centuries of use, its metabolism is still not fully understood, and may play a role in the haemolytic disorders associated with the drug.
METHODS
Incubations of quinine with CYPs
Blackwater fever (BWF) is a rare but serious complication of malaria that is a consequence of antimalarial treatment. Its prevalence seems to have increased. Its diagnosis is based on clinical symptoms and urine color. We report on 4 BWF cases admitted to the infectious diseases The effect of quinine on fever induced by lipopolysaccharide and brewer's yeast has been investigated in rats. Oral administration of 50 or 100 mg kg(-1) quinine, doses which had no effect on normothermic rats, significantly reduced lipopolysaccharide- (50 microg kg(-1), i.m.) and yeast- (2 g
