I read with interest the recent analysis by Eick-Cost and others, which examined associations among U.S. military personnel between various neurologic and psychiatric diagnoses and earlier use of mefloquine. Although not accounting formultiple hypothesis testing, the authors’ finding in subgroup analysis of a significantly increased risk of posttraumatic stress disorder (PTSD) with use of meflo...

BACKGROUND For all medications, there is a trade-off between benefits and potential for harm. It is important for patient safety to detect drug-event combinations and analyze by appropriate statistical methods. Mefloquine is used as chemoprophylaxis for travelers going to regions with known chloroquine-resistant Plasmodium falciparum malaria. As such, there is a concern about serious adverse ev...

Abstract 
 Background: the most prevalent and pathogenic malaria parasite associated with severe illness death is Plasmodium falciparum. In non-endemic countries like Russian federation, P. falciparum a relatively rare but potentially fatal disease found in travelers returning from high burden.
 Aims: this review aims to analyze recommendations for managing different World Health Orga...

Mefloquine sensitivity of Plasmodium falciparum along the Thai-Myanmar border, both in vitro and in vivo, following different first-line treatments for uncomplicated falciparum malaria patients in these areas during the period 1997--2003 were studied. Standard in vitro micro tests and in vivo efficacy according to World Health Organization methodologies were performed. P. falciparum isolates al...

BACKGROUND Artemisinin-based combinations are judged the best treatments for multidrug-resistant Plasmodium falciparum malaria. Artesunate-mefloquine is widely recommended in southeast Asia, but its high cost and tolerability profile remain obstacles to widespread deployment. To assess whether dihydroartemisinin-piperaquine is a suitable alternative to artesunate-mefloquine, we compared the saf...

Three thermally and hydrolytically stable silylamide trioxanes have been prepared from the natural trioxane artemisinin in only five simple chemical steps and in at least 56% overall yield. Two of these new chemical entities completely cured malariainfected mice at a single oral dose of only 8 mg/kg combined with 24 mg/kg of mefloquine hydrochloride. The high efficacy of this ACT chemotherapy i...

We report for the first time a patient with malaria due to Plasmodium vivax who showed R2 resistance to chloroquine and R3 resistance to mefloquine in the Brazilian Amazon region based on WHO clinical criteria for diagnosis of malaria resistance. Failure was observed with unsupervised oral chloroquine, chloroquine under rigorous supervision and mefloquine in the same scheme. Finally, the patien...

mefloquine (mfq), as a racemic mixture is used for the prophylaxis and treatment of malaria. stereoselective pharmacodynamic and pharmacokinetic differences have been observed for mfq. in the present study, the human blood was spiked with racemic mfq. the concentration of mfq enantiomers in various blood fractions including packed erythrocyte layer, platelet rich plasma and platelet poor plasma...

From March 1996 to August 1997, a study was carried out in a malaria endemic area of the Brazilian Amazon region. In vivo sensitivity evaluation to antimalarial drugs was performed in 129 patients. Blood samples (0.5 ml) were drawn from each patient and cryopreserved to proceed to in vitro studies. In vitro sensitivity evaluation performed using a radioisotope method was carried out with the cr...
