GRIS-PEG vs LYNOZYFIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Griseofulvin binds to and disrupts microtubule function by interfering with the polymerization of tubulin, thereby inhibiting fungal cell mitosis and nucleic acid synthesis.
Selective serotonin reuptake inhibitor (SSRI); inhibits serotonin transporter (SERT) in the presynaptic terminal, increasing synaptic serotonin levels.
For tinea capitis and other dermatophyte infections: 500 mg oral daily as a single dose or in divided doses. For more severe infections, up to 1 g daily in divided doses.
1000 mg intravenously every 12 hours infused over 2 hours

Terminal elimination half-life 14-24 hours. With continuous therapy, time to steady-state is ~3-5 days.
Terminal elimination half-life is 12.4 hours (range 11.2–14.1 hours) in patients with normal renal function; allows twice-daily dosing for steady-state within 3 days.
Primarily renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
Renal excretion of unchanged drug accounts for approximately 65% of elimination; biliary/fecal excretion accounts for 25%; the remaining 10% is metabolized by hepatic CYP3A4-mediated oxidation.
