A fixed-dose combination antiretroviral medication containing the nucleoside reverse transcriptase inhibitor (NRTI) emtricitabine, the nucleotide reverse transcriptase inhibitor (NtRTI) tenofovir disoproxil, and the non-nucleoside reverse transcriptase inhibitor (NNRTI) rilpivirine. It is approved and used in the treatment of HIV-1 infection in adults and some adolescents.
Pharmacokinetics
Pharmacokinetic parameters summarized from published studies in healthy HIV-negative and HIV-infected adult subjects receiving the fixed-dose combination orally under fed conditions (emtricitabine 200 mg, tenofovir disoproxil fumarate 245 mg, rilpivirine 25 mg, once daily).
