The investigators propose a small pharmacokinetic study of CD to determine if current 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. 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 pharmacokinetic (PK) analyses performed.
