Terminal half-life 25-48 hours; supports twice-daily dosing with steady state achieved in 7-14 days.
Terminal elimination half-life is approximately 30 hours (range 15-42 h) for regorafenib and 25-60 h for its active metabolites M-2 and M-5. Steady-state is reached within 2-3 weeks.
Fecal (77% as unchanged drug and metabolites), renal (19% as metabolites, <1% as unchanged drug).
Approximately 51% fecal (as unchanged drug and metabolites), 19% renal (as metabolites, <1% unchanged).
