Alternative oxidase inhibitors potentiate the activity of atovaquone against Plasmodium falciparum. (1/172)

Recent evidence suggests that the malaria parasite Plasmodium falciparum utilizes a branched respiratory pathway including both a cytochrome chain and an alternative oxidase. This branched respiratory pathway model has been used as a basis for examining the mechanism of action of two antimalarial agents, atovaquone and proguanil. In polarographic assays, atovaquone immediately reduced the parasite oxygen consumption rate in a concentration-dependent manner. This is consistent with its previously described role as an inhibitor of the cytochrome bc1 complex. Atovaquone maximally inhibited the rate of P. falciparum oxygen consumption by 73% +/- 10%. At all atovaquone concentrations tested, the addition of the alternative oxidase inhibitor, salicylhydroxamic acid, resulted in a further decrease in the rate of parasite oxygen consumption. At the highest concentrations of atovaquone tested, the activities of salicylhydroxamic acid and atovaquone appear to overlap, suggesting that at these concentrations, atovaquone partially inhibits the alternative oxidase as well as the cytochrome chain. Drug interaction studies with atovaquone and salicylhydroxamic acid indicate atovaquone's activity against P. falciparum in vitro is potentiated by this alternative oxidase inhibitor, with a sum fractional inhibitory concentration of 0.6. Propyl gallate, another alternative oxidase inhibitor, also potentiated atovaquone's activity, with a sum fractional inhibitory concentration of 0.7. Proguanil, which potentiates atovaquone activity in vitro and in vivo, had a small effect on parasite oxygen consumption in polarographic assays when used alone or in the presence of atovaquone or salicylhydroxamic acid. This suggests that proguanil does not potentiate atovaquone by direct inhibition of either branch of the parasite respiratory chain.  (+info)

Atovaquone-proguanil compared with chloroquine and chloroquine-sulfadoxine-pyrimethamine for treatment of acute Plasmodium falciparum malaria in the Philippines. (2/172)

This randomized, open-label clinical trial compared a fixed-dose combination of atovaquone and proguanil (n=55) with chloroquine (n=23) or a combination of chloroquine, sulfadoxine, and pyrimethamine (n=32) for treatment of acute falciparum malaria in the Philippines. Patients were hospitalized for 28 days to ensure medication compliance and prevent reinfection. Atovaquone-proguanil produced a significantly higher cure rate (100%) compared with that for chloroquine (30.4%; P<.0001) or chloroquine-sulfadoxine-pyrimethamine (87.5%; P<.05). Treatments did not differ significantly with respect to parasite clearance time (mean: 46.7 h for atovaquone-proguanil, 60.0 h for chloroquine, and 42.8 h for chloroquine-sulfadoxine-pyrimethamine) or fever clearance time (mean, 38.8, 46.8, and 34.5 h, respectively). Adverse events were typical of malaria symptoms; the most frequently reported events were vomiting (18% for atovaquone-proguanil, 17% for chloroquine, and 9% for chloroquine-sulfadoxine-pyrimethamine), abdominal pain (15%, 17%, and 3%, respectively), anorexia (11%, 13%, and 0%, respectively), and headache (6%, 17%, and 3%, respectively). Atovaquone-proguanil was well tolerated and more effective than chloroquine or chloroquine-sulfadoxine-pyrimethamine for treatment of multidrug-resistant falciparum malaria in the Philippines.  (+info)

Prophylactic activity of atovaquone against Plasmodium falciparum in humans. (3/172)

The prophylactic antimalarial activity of atovaquone was determined in a randomized, double-blind, placebo-controlled study of healthy volunteers who were challenged by the bite of Plasmodium falciparum-infected Anopheles stephensi. Subjects were randomly assigned to one of three groups: six received seven daily doses of 750 mg of atovaquone, starting the day before challenge; six received a single dose of 250 mg of atovaquone the day before challenge; and four received placebo. Polymerase chain reaction- and culture-confirmed parasitemia developed in all four placebo recipients, but in none of the drug recipients, indicating that either of the atovaquone regimens provides effective prophylaxis (P = 0.005). However, in low-dose recipients, the drug levels by day 6.5 were profoundly subtherapeutic, indicating that parasites were eliminated prior to the establishment of erythrocytic infection. Atovaquone thus protects non-immune subjects against mosquito-transmitted falciparum malaria, and has causal prophylactic activity.  (+info)

A randomized, double-blind, placebo-controlled field trial to determine the efficacy and safety of Malarone (atovaquone/proguanil) for the prophylaxis of malaria in Zambia. (4/172)

Malaria poses a major health risk to people who are exposed to infection in malaria-endemic areas. A randomized, double-blind, placebo-controlled study was conducted to determine the efficacy and safety of Malarone (250 mg of atovaquone/100 mg of proguanil hydrochloride per tablet) for the chemoprophylaxis of Plasmodium falciparum malaria in Zambia. Adult volunteers received a three-day treatment course of Malarone to eliminate pre-existing parasitemia and were then immediately randomized to treatment with either one Malarone tablet daily (n = 136), or one placebo tablet daily (n = 138) for at least 10 weeks. Malaria blood smears were prepared on a weekly basis and a failure of chemoprophylaxis was defined as any subject who had a positive blood smear, or who withdrew from the study due to a treatment-related adverse event. The prophylaxis success rates in the Malarone and placebo groups were 98% and 63%, respectively (P < 0.001). The most commonly reported adverse events with at least a possible causal relationship to study medication were headache and abdominal pain, which occurred with a higher incidence in the placebo group. No subjects were withdrawn from the study due to a treatment-related adverse event. Thus, Malarone appears to have an excellent safety and efficacy profile for the chemoprophylaxis of P. falciparum infection.  (+info)

Efficacy and safety of atovaquone/proguanil compared with mefloquine for treatment of acute Plasmodium falciparum malaria in Thailand. (5/172)

The increasing frequency of therapeutic failures in falciparum malaria underscores the need for novel, rapidly effective antimalarial drugs or drug combinations. Atovaquone and proguanil are blood schizonticides that demonstrate synergistic activity against multi-drug-resistant Plasmodium falciparum in vitro. In an open-label, randomized, controlled clinical trial conducted in Thailand, adult patients with acute P. falciparum malaria were randomly assigned to treatment with atovaquone and proguanil/hydrochloride (1,000 mg and 400 mg, respectively, administered orally at 24-hr intervals for three doses) or mefloquine (750 mg administered orally, followed 6 hr later by an additional 500-mg dose). Efficacy was assessed by cure rate (the percentage of patients in whom parasitemia was eliminated and did not recur during 28 days of follow-up), parasite clearance time (PCT), and fever clearance time (FCT). Safety was assessed by sequential clinical and laboratory assessments for 28 days. Atovaquone/proguanil was significantly more effective than mefloquine (cure rate 100% [79 of 79] vs. 86% [68 of 79]; P < 0.002). The atovaquone/proguanil and mefloquine treatments did not differ with respect to PCT (mean = 65 hr versus 74 hr) or FCT (mean = 59 hr versus 51 hr). Adverse events were generally typical of malaria symptoms and each occurred in < 10% of the patients in either group, with the exception of increased vomiting found in the atovaquone/proguanil group. Transient elevations of liver enzyme levels occurred more frequently in patients treated with atovaquone/proguanil than with mefloquine, but the differences were not significant and values returned to normal by day 28 in most patients. The combination of atovaquone and proguanil was well tolerated and more effective than mefloquine in the treatment of acute uncomplicated multidrug-resistant falciparum malaria in Thailand.  (+info)

Malarone (atovaquone and proguanil hydrochloride): a review of its clinical development for treatment of malaria. Malarone Clinical Trials Study Group. (6/172)

The continuing spread of drug-resistant malaria emphasizes the need for new antimalarial drugs. Atovaquone is a broad-spectrum antiprotozoal drug with a novel mechanism of action, via inhibition of parasite mitochondrial electron transport, and a favorable safety profile. Early studies with atovaquone alone for treatment of malaria demonstrated good initial control of parasitemia but an unacceptable rate of recrudescent parasitemia. Parasites isolated during recrudescence after treatment with atovaquone alone were resistant to atovaquone in vitro. The combination of atovaquone and proguanil is synergistic in vitro, and clinical studies demonstrated enhanced efficacy of the combination compared to either drug alone for treatment of malaria. Malarone, a fixed-dose combination of 250 mg of atovaquone and 100 mg of proguanil hydrochloride, is available in many countries for treatment of acute, uncomplicated malaria caused by Plasmodium falciparum. At the recommended dose (in adults, four tablets once a day for three days), the overall cure rate was > 98% in more than 500 patients with falciparum malaria. In four randomized, controlled clinical trials, treatment with atovaquone and proguanil hydrochloride was significantly more effective than mefloquine (Thailand), amodiaquine (Gabon), chloroquine (Peru and the Philippines) or chloroquine plus pyrimethamine/sulfadoxine (Philippines). In clinical trials where the comparator drug was highly effective, treatment with atovaquone and proguanil hydrochloride was equally effective. Parasites isolated during recrudescence after treatment with the combination of atovaquone and proguanil were not resistant to atovaquone in vitro. The most commonly reported adverse events in clinical trials (abdominal pain, anorexia, nausea, vomiting, diarrhea and coughing) occurred with similar frequency in patients treated with a comparator drug. Malarone is a safe and effective new agent for treatment of malaria.  (+info)

A mechanism for the synergistic antimalarial action of atovaquone and proguanil. (7/172)

A combination of atovaquone and proguanil has been found to be quite effective in treating malaria, with little evidence of the emergence of resistance when atovaquone was used as a single agent. We have examined possible mechanisms for the synergy between these two drugs. While proguanil by itself had no effect on electron transport or mitochondrial membrane potential (DeltaPsim), it significantly enhanced the ability of atovaquone to collapse DeltaPsim when used in combination. This enhancement was observed at pharmacologically achievable doses. Proguanil acted as a biguanide rather than as its metabolite cycloguanil (a parasite dihydrofolate reductase [DHFR] inhibitor) to enhance the atovaquone effect; another DHFR inhibitor, pyrimethamine, also had no enhancing effect. Proguanil-mediated enhancement was specific for atovaquone, since the effects of other mitochondrial electron transport inhibitors, such as myxothiazole and antimycin, were not altered by inclusion of proguanil. Surprisingly, proguanil did not enhance the ability of atovaquone to inhibit mitochondrial electron transport in malaria parasites. These results suggest that proguanil in its prodrug form acts in synergy with atovaquone by lowering the effective concentration at which atovaquone collapses DeltaPsim in malaria parasites. This could explain the paradoxical success of the atovaquone-proguanil combination even in regions where proguanil alone is ineffective due to resistance. The results also suggest that the atovaquone-proguanil combination may act as a site-specific uncoupler of parasite mitochondria in a selective manner.  (+info)

Pharmacokinetics of azithromycin administered alone and with atovaquone in human immunodeficiency virus-infected children. The ACTG 254 Team. (8/172)

To evaluate if atovaquone (ATQ) interacts pharmacokinetically with azithromycin (AZ) in human immunodeficiency virus-infected children, 10 subjects (ages, 4 to 13 years) were randomized in a crossover study to receive AZ (5 mg/kg/day) alone (ALONE) or AZ (5 mg/kg/day) and ATQ (30 mg/kg/day) simultaneously (SIM) prior to receiving AZ and ATQ staggered by 12 h. Despite a lack of significant difference in the mean AZ pharmacokinetic parameters, the steady-state values of AZ's area under the concentration-time curve from 0 to 24 h and maximum concentration in serum were consistently lower (n = 7 of 7) for the SIM regimen than they were for the ALONE regimen. A larger study will be required to determine if ATQ affects AZ pharmacokinetics and efficacy in a clinically significant manner.  (+info)

Malarone® (atovaquone/proguanil) is frequently used in malaria prophylaxis. Unfortunately, there are indications that certain anti-HIV agents may decrease atovaquone plasma levels by induction of atovaquone metabolism.. For travelling HIV patients, the clinical consequences of these possible drug drug interactions are serious, since a diminished exposure to the anti-malarial drug will result in suboptimal prophylaxis of malaria and potential development of drug resistant strains of Plasmodium falciparum.. The purpose of this study is to find out if HIV patients using HAART regimes with either lopinavir/ritonavir, atazanavir/ritonavir or efavirenz have lower atovaquone plasma levels than healthy volunteers after a single dose of atovaquone/proguanil. ...
Atovaquone is used as a fixed-dose combination with proguanil (Malarone) for treating children and adults with uncomplicated malaria or as chemoprophylaxis for preventing malaria in travellers. Indeed, in the USA, between 2009 and 2011, Malarone prescriptions accounted for 70% of all antimalarial pre-travel prescriptions. In 2013 the patent for Malarone will expire, potentially resulting in a wave of low-cost generics. Furthermore, the malaria scientific community has a number of antimalarial quinolones with a related pharmacophore to atovaquone at various stages of pre-clinical development. With this in mind, it is timely here to review the current knowledge of atovaquone, with the purpose of aiding the decision making of clinicians and drug developers involved in the future use of atovaquone generics or atovaquone derivatives.. ...
Tumour hypoxia renders cancer cells resistant to cancer therapy, resulting in markedly worse clinical outcomes. To find clinical candidate compounds that reduce hypoxia in tumours, we conduct a high-throughput screen for oxygen consumption rate (OCR) reduction and identify a number of drugs with this property. For this study we focus on the anti-malarial, atovaquone. Atovaquone rapidly decreases the OCR by more than 80% in a wide range of cancer cell lines at pharmacological concentrations. In addition, atovaquone eradicates hypoxia in FaDu, HCT116 and H1299 spheroids. Similarly, it reduces hypoxia in FaDu and HCT116 xenografts in nude mice, and causes a significant tumour growth delay when combined with radiation. Atovaquone is a ubiquinone analogue, and decreases the OCR by inhibiting mitochondrial complex III. We are now undertaking clinical studies to assess whether atovaquone reduces tumour hypoxia in patients, thereby increasing the efficacy of radiotherapy.

Background. Trimethoprim-sulfamethoxazole (TMP-SMZ) has been used extensively for the prevention of Pneumocystis carinii (also referred to as Pneumocystis jiroveci) pneumonia (PCP) and other opportunistic infections in human immunodeficiency virus (HIV)-infected children. Because the efficacy of TMP-SMZ for treatment of bacterial infections is limited, it is sometimes poorly tolerated, and there is risk of emergence of drug-resistant strains associated with widespread use, we evaluated a regimen that included atovaquone and azithromycin.. Methods. A randomized, double-blind, placebo-controlled trial was designed to determine whether atovaquone-azithromycin had equivalent efficacy to TMP-SMZ for the prevention of serious bacterial infections and to compare the long-term tolerance, PCP breakthrough rates, and nonserious bacterial infection rates among HIV-infected children aged 3 months to 19 years. Children qualified for PCP prophylaxis (on the basis of Centers for Disease Control and ...

Although SMX/TMP remains the drug of choice for PCP prophylaxis, drug sensitivity may limit its use. Atovaquone has demonstrated greater safety than SMX/TMP and thus is suitable as a candidate drug for treatment and prophylaxis of PCP. Azithromycin, with a broad anti-microbial spectrum (including mycoplasma and atypical mycoplasma), is an attractive prophylactic agent for use in children with HIV infection, due to its relative safety and once-daily dosing regimen. Therefore, the combination of atovaquone and azithromycin may offer broader antimicrobial coverage and greater safety than SMX/TMP.. Patients are randomized to receive either SMX/TMP or combination micronized atovaquone/azithromycin. Crossover to the alternative regimen may occur if serious toxicity is observed. Patients are monitored for occurrence of serious bacterial infections or PCP breakthrough, and when a serious bacterial infection occurs, patients are crossed over to the alternative regimen. Treatment continues until 2 years ...

In these studies, 48% of subjects were classified as other racial/ethnic groups, primarily Asian; 42% of subjects were black and the remaining subjects were white. Attributable adverse experiences that occurred in ≥ 5% of patients were abdominal pain (17%), nausea (12%), vomiting (12%), headache (10%), diarrhea (8%), asthenia (8%), anorexia (5%), and dizziness (5%). Treatment was discontinued prematurely due to an adverse experience in 4 of 436 (0.9%) adolescents and adults treated with atovaquone and proguanil hydrochloride.. In two controlled trials, 116 pediatric patients (weighing 11 kg to 40 kg) (mean age 7 years) received atovaquone and proguanil hydrochloride for the treatment of malaria.

Risk Summary Available data from published literature and postmarketing experience with use of atovaquone and proguanil hydrochloride in pregnant women are insufficient to identify a drug-associated risk for major birth defects, miscarriage, or adverse maternal or fetal outcomes. The proguanil component of atovaquone and proguanil hydrochloride tablets acts to inhibit parasitic dihydrofolate reductase; however, pregnant women and females of reproductive potential should continue folate supplementation to prevent neural tube defects [see Clinical Pharmacology (12.4)]. Pregnant women with malaria are at increased risk for adverse pregnancy outcomes (see Clinical Considerations). Atovaquone administered by oral gavage to pregnant rats and rabbits during the period of organogenesis was not associated with fetal malformations at plasma exposures approximately 7 times and equal to, respectively, the estimated human exposure for the treatment of malaria based on AUC. Proguanil administered to pregnant ...
Malarone belongs to a group of medicines called antimalarials. It contains two active ingredients, atovaquone and proguanil hydrochloride. Malaria is spread by the bite of an infected mosquito, which passes the malaria parasite (Plasmodium falciparum) into the bloodstream.

According to the guidelines for India[8] Chemoprophylaxis should be administered only in selective groups in high P.falciparum endemic areas. Use of personal protection measures is encouraged for pregnant women and other vulnerable population including travellers. However, for longer stay of Military and Para-military forces in high Pf endemic areas, the practice of chemoprophylaxis is to be followed wherever appropriate. For Short term chemoprophylaxis (up to 6 weeks) Doxycycline, is the drug of choice. Chemoprophylaxis for longer stay (more than 6 weeks) is with Mefloquine.. Regimens currently recommended for use in South Africa (2009), include Mefloquine, Doxycycline or Atovaquone - proguanil.[9]. Guidelines from the Health Protection Agency Advisory Committee on Malaria Prevention (ACMP) in UK travellers (2007) recommend Mefloquine, or Doxycycline or Atovaquone/Proguanil for travel to high risk areas of Bangladesh and India. Chloroquine plus proguanil is recommended as an alternative. For ...

A 50-year-old Nigerian man was admitted for generalized non febrile seizures. Two weeks before his GP prescribed antimalaric prophilaxis with clorochine for a planned trip in his home country. He suffered of a minor stroke 2 years before with no residual disability. He had also history of arterial hypertension treated with ace inhibitors and aspirin. At admission he was treated with lorazepam i.v. for a second generalized crisis at admission, and started carbamazepine 1000 per day. No other critical events were found during in hospital staying. A CT scan demonstrated the known subcortical right hemispheric hypodensity with no sulcal effacement or swelling features. Three months later carbamazepine was gradually intterrupted. After few months a new trip to Lagos was planned and chosen an antimalaric prophilaxis with Proguanil/Atovaquone (Malarone). The drug was well tolerated and no side effects were detected..

Joseph Bozorgmehr also notes that [i]n many instances...a loss of function and regulation in a harsh or unusual environment can have a beneficial outcome and thus be selected for-bacteria tend to evolve resistance to antibiotics in such a way through mutations that would otherwise adversely affect membrane permeability.20. Parasites. Humans have been battling malaria for thousands of years. The advent of modern medicine provided us with a weapon to finally beat this ravaging parasite once and for all. Or so we thought. Unfortunately for us, malaria has been able to develop immunity to every drug weve thrown at it. For example, malaria quickly developed resistance to Atovaquone. All that was required to circumvent the effectiveness of this drug was a single point mutation at position 268 in a single malarial gene. The odds of developing this particular mutation are one in a trillion (1012). While those odds would be difficult to overcome for most organisms (such as human beings or beetles), ...

In vitro studies have indicated that the antifolates pyrimethamine [4, 6] and cycloguanil (the active metabolite of proguanil) suppress the proliferation of stimulated human lymphocytes; proguanil has no effect [2]. During the early growth phase of the cells, 14C-thymidine (14C-TdR) incorporation is increased by pyrimethamine and cycloguanil, reflecting blockage of endogenous TdR synthesis [3]. Proguanil (Paludrine) is increasingly being used for malaria prophylaxis. It is considered the most innocuous of the antimalarials currently employed. Since nothing is known about the effect of oral proguanil on human lymphocytes, the present study was undertaken. Little information is available about the serum levels of proguanil and cycloguanil following ingestion of prophylactic doses [8]. Therefore, the serum concentrations of proguanil and cycloguanil were estimated, to allow comparison with previous in vitro studies [2 ...
Doxycycline. There is no evidence for human teratogenicity with doxycycline use during pregnancy. 8 Despite this, the main concern with doxycycline, like tetracycline, is the risk to the fetus of inhibition of bone growth and discoloration and dysplasia of the teeth, 3 which can occur during the period of calcification beyond the fourth month of gestational age. 4 Because of the potential harm, doxycycline is not recommended during pregnancy. However, keeping in mind that treatment is continued for 4 weeks after leaving the malaria-endemic area, 9 doxycycline can be considered as long as treatment is completed by the fourth month of pregnancy.. Atovaquone-proguanil. Proguanil has been used as a malarial prophylactic agent for decades, with no known toxic effects on the fetus. 10 Four small 3-day treatment studies with the atovaquone-proguanil combination in the second and third trimesters of pregnancy did not identify any adverse effects in the fetuses or newborns. 11-14 In a recent ...

I am pleased to announce our latest research project: my staff and I are participating in the following very important initiative.. 3 Day Malarone Acceptability and Tolerability research project (3MAT). Malaria is one of the most common causes of fever in Australian travellers, with approximately 400 cases reported each year in Australia. Most travellers who develop malaria did not take anti-malarial medications, or did not take the medications properly (e.g. forgot to take tablets). Malaria is a serious illness and can potentially be fatal.. A research project is being conducted with the aim to make it easier and cheaper to take malaria pills and thus reduce the risk of malaria in travellers. Malarone is a safe and effective anti-malarial medication. The standard dosage of Malarone for prevention of malaria is one tablet per day, starting 2 days before travelling to a malaria area, daily while in a malaria area, and continuing until 7 days after leaving the malaria area.. Research has shown ...
Thus far, malaria control has primarily focused on destroying mosquito breeding sites, using insecticides and preventing human contact using mosquito nets and screens (White, 2004). However, malaria predominantly affects lesser economically developed countries and thus the cost of treatment serves as a barrier to disease eradication. Anti-malarial drugs are some of the most common medications provided in tropical countries. They generally function by inhibiting specific enzymes or making the environment difficult for the parasite to survive in (Basore et al., 2015). Drugs are relatively cheaper, widely available and, as there is no vaccine, they currently provide the most effective method of treatment (White, 2004). One such class is Atovaquone. It works by inhibiting mitochondrial electron transport in the malarial parasite and preventing the build-up of an electrochemical gradient (Vaidya and Mather, 2000). This would prevent Plasmodium parasites from producing ATP via oxidative ...
Our investigations reveal that cGAS contributes to parasite control, which is essential for the formation of GC-derived humoral immunity. The ability to simultaneously identify and analyze endogenous polyclonal antigen-specific CD4+ T cells and B cells responding to Plasmodium has revealed a profound effect of innate immune control of parasitemia. Control of parasitemia is important for timely development of the GC response, a response critical for both the efficient generation of high-affinity antibodies and durable immune memory (59-62). Furthermore, our ability to track parasitemia throughout the course of infection combined with the potential to rapidly clear blood-stage infection with atovaquone provided us with an elegant system in which the effects of innate control of parasite burden could be disentangled from the effects of early innate signals on the adaptive immune response. Specifically, the collapse of the GC response in cGAS-/- mice as parasitemia persisted could be abolished with ...
Cancer cells have upregulated glycolysis compared with normal cells, which has led many to the assumption that oxidative phosphorylation (OXPHOS) is downregulated in all cancers. However, recent studies have shown that OXPHOS can be also upregulated in certain cancers, including leukemias, lymphomas, pancreatic ductal adenocarcinoma, high OXPHOS subtype melanoma, and endometrial carcinoma, and that this can occur even in the face of active glycolysis. OXPHOS inhibitors could therefore be used to target cancer subtypes in which OXPHOS is upregulated and to alleviate therapeutically adverse tumor hypoxia. Several drugs including metformin, atovaquone, and arsenic trioxide are used clinically for non-oncologic indications, but emerging data demonstrate their potential use as OXPHOS inhibitors. We highlight novel applications of OXPHOS inhibitors with a suitable therapeutic index to target cancer cell metabolism. Clin Cancer Res; 24(11); 2482-90. ©2018 AACR.

It works by killing the parasites in the blood and also in the liver. It is effective against strains of falciparum malaria which may be resistant to other antimalarials and so is especially useful for those travelling to places where there is a high risk of encountering malaria which is resistant to other drugs. It would be particularly useful for those individuals who cannot tolerate, or who are unable to take mefloquine ...
