Distribution: Crosses placenta, enters breast milk. Plasma protein binding: <4%.
Metabolism: Metabolised minimally via oxidation and glucuronide conjugation. Phosphorated intracellularly to emtricitabine 5’-triphosphate.
Excretion: Via urine (86% as unchanged drug, 13% as metabolites, 9% as oxidative metabolite, 4% as glucuronide metabolite); faeces (14%). Elimination half-life: Approx 10 hours (emtricitabine). Intracellular half-life: 39 hours (emtricitabine 5’-triphosphate).
