At a time when Fansimef, the fixed combination of mefloquine, sulfadoxine and pyrimethamine was considered for prophylaxis of falciparum malaria, a randomized double-blind study comparing the efficacy and tolerability of Fansimef with that of Lariam (mefloquine), Fansidar, chloroquine and placebo in malaria prophylaxis was performed in Thailand from July 1987 to January 1988. The study population of 602 adult males was recruited in Pak Tongchai District, some 360 km North-East of Bangkok, where multiresistant P. falciparum is endemic. All active treatments and placebo were given once weekly for 24 weeks with doses as follows: Fansimef: 125 mg mefloquine + 250 mg sulfadoxine + 12.5 mg pyrimethamine (1 half-strength tablet); Lariam: 125 mg mefloquine (1 half-strength tablet); Fansidar: 500 mg sulfadoxine + 25 mg pyrimethamine; chloroquine; 300 mg. A loading dose of 2 half-strength tablets was given in the Fansimef group in weeks 1 and 2 and in the Lariam group in weeks 1 to 4. The incidence of acute episodes of P. falciparum per 100 person months of prophylaxis was 0.17 each in the Fansimef and the Lariam groups, 1.18 in the Fansidar group, 0.69 in the chloroquine group and 0.64 in the placebo group (differences statistically not significant). Clinically adverse events were reported by 170 subjects (Fansimef 28, Lariam 29, Fansidar 41, choroquine 43, placebo 29; differences statistically not significant). The most frequent adverse events in all groups were headache, sleepiness, dizziness and weakness.(ABSTRACT TRUNCATED AT 250 WORDS)

A double-blind comparative study of Fanismef-mefloquine/sulfadoxine/pyrimethamine (MSP) and Lariam-mefloquine (MEF) for the treatment of falciparum malaria, was carried out at malaria clinics in Kanchanaburi, in western Thailand, in the years 1987 and 1988. The cure rates obtained were 96% for the MSP group and 93% for the MEF and there was no significant difference. Vomiting and diarrhea were common side effects in both the MSP and MEF groups. Less common side effects were epigastric pain, minor skin rashes and dizziness. Significant differences in vomiting and epigastric pain only occurred in the patients who did not have these symptoms before treatment: vomiting MSP 23%, MEF 8%, epigastric pain MSP 22% and MEF 11%.

Background: Mefloquine (MQ) is an important antimalarial drug. Dizziness and other adverse neuropsychiatric reactions have however restricted its use. Method: Ten healthy adult volunteers were given MQ (Lariam) 250 mg once weekly for 16 weeks. Measurement of postural sway (posturography), nystagmus recording, determinations of hearing thresholds (Bekesy audiometry), and determinations of drug concentrations were done before, after 4, 32, and 109 days of weekly MQ intake and 3 months after the last dose. Results: All volunteers were able to continue their professional work and normal daily activities. Several mild symptoms were reported. In at least one of the volunteers, these symptoms were probably caused by the MQ intake. Hearing thresholds remained normal. No significant changes were noted in the nystagmus tests. The recorded values of sway index were within the normal range (99% confidence interval) in all volunteers in all test situations, and no differences were seen at the time of maximal drug concentrations (day 109) compared to before or after the study. There was no correlation between the plasma concentrations of MQ, the two MQ enantiomers (RS and SR), or the main mefloquine metabolite and the sway index. Conclusion: Although no effect was seen on the vestibular system in the present study, further tests in a flight simulator will be needed before MQ can be recommended for pilots.
