GRISACTIN ULTRA vs MYIDYL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Griseofulvin binds to tubulin and disrupts microtubule function, inhibiting fungal cell division and nucleic acid synthesis.
c-Met/ALK inhibitor; inhibits receptor tyrosine kinases MET and ALK, blocking downstream signaling pathways including PI3K/AKT and RAS/RAF/MEK/ERK, leading to reduced tumor cell proliferation and angiogenesis.
500 mg orally once daily or 250 mg orally twice daily; for severe infections, 500 mg twice daily or 250 mg three times daily. Maximum daily dose: 1 g. Administer with or after meals.
50 mg orally twice daily without regard to meals.

Terminal elimination half-life ranges from 6.5 to 9 hours (mean ~7.5 hours) in patients with normal hepatic function; prolonged in hepatic impairment.
Terminal elimination half-life is approximately 12 hours (range 10–14 hours) in adults with normal renal function; prolonged in renal impairment (up to 24–30 hours).
Primarily hepatic metabolism; less than 1% excreted unchanged in urine; approximately 30-50% of a dose is eliminated in feces as metabolites, with minor biliary excretion.
Primarily renal excretion as unchanged drug (~60%) and metabolites (~30%); biliary/fecal excretion accounts for ~10%.
