Artemether-lumefantrine (six-dose regimen) is more effective than the artemether-lumefantrine (four-dose regimen) or other regimens not containing artemisinin derivatives in treating falciparum malaria. Another recommended combination is dihydroartemisinin and piperaquine. Artemisinin-naphthoquine combination therapy showed promising results in treating falciparum malaria. However, more research is needed to establish its efficacy as a reliable treatment. Artesunate plus mefloquine performs better than mefloquine alone in treating uncomplicated falciparum malaria in low transmission settings. Atovaquone-proguanil is effective against uncomplicated falciparum with a possible failure rate of 5% to 10%; the addition of artesunate may reduce failure rate. Azithromycin monotherapy or combination therapy has not shown effectiveness in treating plasmodium or vivax malaria. Amodiaquine plus sulfadoxine-pyrimethamine may achieve less treatment failures when compared to sulfadoxine-pyrimethamine alone in uncomplicated falciparum malaria. There is insufficient data on chlorproguanil-dapsone in treating uncomplicated falciparum malaria. The addition of primaquine with artemisinin-based combination therapy for falciparum malaria reduces its transmission at day 3-4 and day 8 of infection. Sulfadoxine-pyrimethamine plus artesunate is better than sulfadoxine-pyrimethamine plus amodiaquine in controlling treatment failure at day 28. However, the latter is better than the former in reducing gametocytes in blood at day 7.Infection with P. vivax, P. ovale or P. malariae usually does not require hospitalisation.
There is no difference in effectiveness when using intrarectal quinine compared to intravenous or intramuscular quinine in treating uncomplicated/complicated falciparum malaria. There is insufficient evidence for intramuscular arteether to treat severe malaria. The provision of rectal artesunate before transfer to hospital may reduce the rate of death for children with severe malaria.Cerebral malaria is the form of severe and complicated malaria with the worst neurological symptoms. There is insufficient data on whether osmotic agents such as mannitol or urea are effective in treating cerebral malaria. Routine phenobarbitone in cerebral malaria is associated with fewer convulsions but possibly more deaths. There is no evidence that steroids would bring treatment benefits for cerebral malaria.Managing Cerebral Malaria
Cerebral malaria usually makes a patient comatose, if the cause of the coma is in doubt, test for other locally prevalent causes of encephalopathy (bacterial, viral or fungal infection) should be carried out. In areas where there is a high prevalence of malaria infection (e.g. tropical region) treatment can start without testing first. To manage the cerebral malaria when confirmed the following can be done:

Patients in coma should be given meticulous nursing care ( monitor vital signs, turn patient every 2 hours, avoid lying the patient in a wet bed etc.) A sterile urethral catheter should be inserted to help with urinating
To aspirate stomach content, a sterile nasogastric tube should be inserted.
