The purpose of this study is to find out whether taking certain anti-HIV medicines with certain antimalarial medicines affects the amount of the medicines in the blood.
The study medicines that will be used are artemether/lumefantrine (antimalarial medication) and lopinavir/ritonavir or efavirenz (anti-HIV medications). Artemether/lumefantrine is not approved by the United States Food and Drug Administration (FDA) but is recommended as standard of care medical treatment for malaria in Africa and Asia. Lopinavir/ritonavir and efavirenz are approved by the FDA. Artemether/lumefantrine and lopinavir/ritonavir or efavirenz may need to be used together to treat children in Africa and Asia. We seek to learn about whether or not the use of these medicines together results in a change in blood levels of any of these medicines. The information obtained from this study will help doctors to provide a better treatment to children and adults with malaria and HIV.

Active Comparator: Lopinavir/ritonavir, artemethr/lumefantrine
Determination of the antimalarial drug levels artemether/lumefantrine in the absence and in the presence of co-administered antiretrovirals lopinavir and ritonavir.
|
Drug: Lopinavir/Ritonavir, Efavirenz, Artemether/lumefantrine
participants receive a total of 6 doses of artemether(80mg)/lumefantrine(480mg)for baseline PK evaluation. This is followed by a 26-day course of either efavirenz(600mg) once daily or lopinavir/ritonavir (400mg/100mg) twice daily and additional 6 doses of artemether/lumefantrine to determine the pharmacokinetics of the antimalarial medications in the context of antiretrovirals. The participants undergo at least a 14 day washout period (between the last baseline PK blood draw and the initiation of antiretrovirals) |
