| ATC code: | J05AR03 | route: | oral |
| n-compartments | 1 |
Tenofovir disoproxil and emtricitabine is a fixed-dose combination antiretroviral medication used for the treatment and prevention (pre-exposure prophylaxis, PrEP) of HIV-1 infection in adults and adolescents. Both drugs are reverse transcriptase inhibitors: tenofovir is a nucleotide analog, and emtricitabine is a nucleoside analog. The combination is currently approved and widely used in clinical practice.
Pharmacokinetics
Pharmacokinetics reported in healthy adult volunteers, steady-state, after oral administration under fasting conditions.
