BACKGROUND Malaria control is difficult where there is intense year-round transmission of multiple plasmodium species, such as in Papua New Guinea. METHODS Between April 2005 and July 2007, we conducted an open-label, randomized, parallel-group study of conventional chloroquine-sulfadoxine-pyrimethamine and artesunate-sulfadoxine-pyrimethamine,(More)
AIMS To obtain comprehensive pharmacokinetic and pharmacodynamic data for artesunate (ARTS) and its active metabolite dihydroartemisinin (DHA) following i.v. and oral administration of ARTS to patients with acute, uncomplicated falciparum malaria. METHODS Twenty-six Vietnamese patients with falciparum malaria were randomized to receive either i.v. ARTS(More)
Exposures to carcinogens present in the diet, in cigarette smoke, or in the environment have been associated with increased risk of bladder and colorectal cancer. The aromatic amines and their metabolites, a class of carcinogen implicated in these exposures, can be N- or O-acetylated by the NAT1 and NAT2 enzymes. Acetylation may result in activation to(More)
Piperaquine is a bisquinoline antimalarial drug that was first synthesised in the 1960s, and used extensively in China and Indochina as prophylaxis and treatment during the next 20 years. A number of Chinese research groups documented that it was at least as effective as, and better tolerated than, chloroquine against falciparum and vivax malaria, but no(More)
INTRODUCTION We investigated placental transfer and neurobehavioural effects in neonates exposed to citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine or sertraline (SSRI's), or to venlafaxine (an SNRI). METHODS Women receiving antidepressants during pregnancy and their neonates were studied. Cord and maternal drug concentrations were measured(More)
To provide novel data relating to the dispositions, effects, and toxicities of the artemisinin derivatives in severe malaria, we studied 30 Vietnamese adults with slide-positive falciparum malaria treated with intravenous artesunate. Twelve patients with complications (severe; group 1) and 8 patients without complications but requiring parenteral therapy(More)
OBJECTIVE This study characterized infant drug doses and breast-milk-to-plasma area-under-the-curve ratios for olanzapine and determined plasma concentrations and effects of this drug on breast-feeding infants. METHOD Seven mother-infant nursing pairs were studied. Olanzapine was measured in plasma and milk with high-performance liquid chromatography over(More)
The aim of this study was to elucidate the metabolic pathways for dihydroartemisinin (DHA), the active metabolite of the artemisinin derivative artesunate (ARTS). Urine was collected from 17 Vietnamese adults with falciparum malaria who had received 120 mg of ARTS i.v., and metabolites were analyzed by high-performance liquid chromatography-mass(More)
AIMS To characterize milk/plasma (M/P) ratio and infant dose, for fluoxetine and norfluoxetine, in breast-feeding women taking fluoxetine for the treatment of depression, and to determine the plasma concentration of these drugs in their infants. METHODS Fourteen women (mean age 32.2 years) taking fluoxetine (mean dose 0.51 mg kg-1 day-1 ) and their(More)
AIMS To study the population pharmacokinetics of piperaquine after co-administration with dihydroartemisinin in uncomplicated malaria. METHODS The disposition of piperaquine was studied in 85 Cambodian patients with uncomplicated falciparum or vivax malaria treated with the piperaquine-dihydroartemisinin coformulation Artekin. All patients were given(More)
