    Notes: Summary We have studied the kinetics of a single oral dose of mefloquine (750 mg) in 12 Thai patients with falciparum malaria and have compared the results with those of a previous study in 12 healthy Thai volunteers [6]. All the patients responded to treatment with a mean parasite clearance time of 66.6 h and a mean fever clearance time of 54.1 h. There was no significant difference in peak plasma concentration, time to peak, area under the curve or apparent volume of distribution between patients and controls. However, the terminal half-life (t1/2) and mean residence time (MRT) were shorter in the patients (12.2 vs 16.7 days for t1/2 and 15.5 vs 21.4 days for MRT). We conclude that there are changes in the disposition of mefloquine related to malaria, although the exact basis of the changes is not clear.

    Notes: Summary The kinetics of a single oral dose of mefloquine given either alone or with ampicillin has been studied in 8 healthy Thai male volunteers. There was a significantly higher maximum whole blood mefloquine concentration after coadministration with ampicillin (1648 vs 1228 ng·ml−1), as well as a significantly reduced terminal half life (15.3 vs 17.7 days), mean residence time (20.1 vs 23.4 days) and volume of distribution at steady state (14.1 vs 19.4 l·kg−1). Although there was no significant change in the AUC from zero time to infinity, the AUC from zero time to 5 days was significantly increased by ampicillin (4.86 vs 3.27 μg·ml−1 day). These changes in mefloquine disposition after antibiotic treatment may be due both to an increase in fractional bioavailability and a reduction in the enterohepatic recycling of mefloquine.

    The pharmacokinetics of mefloquine when given alone or in combination with sulphadoxine and pyrimethamine in Thai male and female subjects (1987)

    Notes: Summary The kinetics of mefloquine were studied in 12 healthy Thai male and 12 healthy Thai female volunteers. Mefloquine (MQ) was administered either alone (750 mg orally) or in combination (MSP) with sulphadoxine (1.5 g) and pyrimethamine (75 mg) to each of 6 male and 6 female subjects. Plasma concentrations of MQ were measured by HPLC at intervals for 42 days. There was considerable interindividual variability in the pharmacokinetic parameters; for example in the male subjects receiving MQ alone peak concentrations ranged between 638 and 2494 ng·ml−1 with a mean concentration of 1442 ng·ml−1. Compared to previously published data on MQ concentrations in Caucasian male subjects, the present study indicates that higher concentrations are achieved in Thai subjects. The only significant difference in kinetic parameters between male and female subjects receiving MQ alone was in the mean residence time (MRT) which was greater in females. However, an analysis of pharmacokinetic parameters following administration of the combination preparation showed that the time to peak (tmax) was significantly reduced in females receiving MSP compared to the corresponding females given MQ alone and males given MSP. When data obtained from all subjects (male and female) receiving either MQ alone or MSP were combined, both MRT and half-life were significantly greater in subjects given MSP. There is therefore some evidence that therapeutic concentrations of MQ are maintained for a longer period of time following MSP administration.

    Notes: Summary The kinetics of a single oral dose of mefloquine given either alone or with tetracycline has been studied in 20 healthy Thai male volunteers. There was a significantly higher maximum whole blood mefloquine concentration after coadministration with tetracycline (1600 vs 1160 ng · ml−1), as well as a significantly reduced terminal half-life (14.4 vs 19.3 days), mean residence time (11.9 vs 16.0 days) and volume of distribution at steady state (13.3 vs 19.91 · kg−1). Although there was no significant change in the AUC from zero time to infinity, the AUC from zero time to 7 days was significantly increased by tetracycline (6.18 vs 4.76 μg · ml−1 · day). The changes in mefloquine disposition after tetracycline treatment are probably due to a reduction in enterohepatic recycling. The initial increase in mefloquine AUC without an apparent increase in side-effects suggests that this combination may have a place in the treatment of multi-drug resistant falciparum malaria.
