The investigators propose a small pharmacokinetic study of CD to determine if the current co-formulated fixed combination CD tablets provide an adequate dosage in pregnancy. Such a study is a necessary precursor to any large Phase II trials to further evaluate the safety and efficacy of CD for use in pregnant women. Therefore, the primary objective of this study is to evaluate the pharmacokinetics of CD in pregnancy. To accomplish this, a group of 66 parasitemic pregnant women in this open label trial will receive CD and be sampled by venipuncture at two of the seven follow-up visits scheduled for pharmacokinetic analyses, such that 11 patients are sampled at each of 12 time points. To serve as a reference, 66 non-pregnant women with symptomatic malaria will also be treated with CD and will have identical PK analyses performed.
