Accepts Healthy Volunteers:   No


  • Females and males >=18 years of age with uncomplicated, symptomatic malaria as indicated by the presence of both of the following: a.) Blood smears positive for Plasmodium falciparum asexual parasitemia between 1000 -100,000 parasites/uL; b.) Fever or history of fever ( >=38.5C/101.2F rectal or tympanic; >=37.5C/99.5F axillary or >=38C/100.4F oral) within the prior 24 hours

  • Positive rapid diagnostic test (Binax NOW ICT) positive for P. falciparum
  • Women of childbearing potential must have a negative urine gonadotropin prior to entry into the study and must agree to use adequate contraception during the entire study


  • Severe or complicated malaria including subjects with any of the following: a.) Impaired consciousness (e.g. obtundation, unarousable coma), seizures or abnormal neurologic exam suggestive of severe or complicated malaria; b.) Hemoglobinuria; c.) Jaundice; d.) Respiratory distress (respiratory rate >=30/min); e.) Persistent vomiting; f.) Hematuria, as reported by the patient
  • Pregnant or breast-feeding women
  • History of allergy to or hypersensitivity to azithromycin or any macrolide, sulfonamides, pyrimethamine, or chloroquine
  • Known or suspected folate deficiency

  • Known G-6PD deficiency
  • History of epilepsy or psoriasis
  • History of treatment with any antimalarial drug (chloroquine, quinine, mefloquine, Malarone, SP, artemisinin compounds) or antibacterial with known antimalarial activity (macrolides, doxycycline, clindamycin) within 2 weeks prior to enrollment into the study
  • Known or suspected cardiovascular, hepatic or renal abnormality that in the opinion of the Investigator would place the subject at increased risk to participate in the study. The following findings are specific exclusions: a.) Serum creatinine >2.0 x ULN; b.) ALT and/or AST >3 x ULN
  • Inability to swallow oral medication in tablet form
  • Treatment with other investigational drugs within 30 days prior to enrollment into the study
  • Alcohol and/or any other drug abuse
  • Requirement to use medication during the study that might interfere with the evaluation of the study drug
