CRESEMBA vs GRISEOFULVIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Isavuconazole, the active moiety of CRESEMBA, inhibits fungal cytochrome P450-dependent 14-alpha-demethylase, thereby blocking the conversion of lanosterol to ergosterol, disrupting fungal cell membrane synthesis and function.
Binds to microtubular protein tubulin, disrupting mitotic spindle formation and inhibiting fungal cell mitosis. Also interferes with fungal nucleic acid synthesis and cell wall deposition.
200 mg intravenously every 8 hours for the first 48 hours (6 doses), then 200 mg intravenously once daily; or 200 mg orally three times daily for the first 48 hours (6 doses), then 200 mg orally once daily.
500 mg orally once daily or 250 mg orally twice daily; microsize formulation: 500-1000 mg orally once daily; ultramicrosize formulation: 330-375 mg orally once daily. Administer with fatty meal to enhance absorption.

Clinical Note
moderateGriseofulvin + Estrone sulfate
"The metabolism of Estrone sulfate can be increased when combined with Griseofulvin."
Clinical Note
moderateGriseofulvin + Tranilast
"The risk or severity of adverse effects can be increased when Griseofulvin is combined with Tranilast."
Clinical Note
moderateGriseofulvin + Tolfenamic acid
"The risk or severity of adverse effects can be increased when Griseofulvin is combined with Tolfenamic acid."
Clinical Note
moderateGriseofulvin + Nimesulide
Terminal elimination half-life is approximately 24 hours (range 20-30 hours) after oral administration, supporting once-daily dosing; steady-state achieved by Day 4-5.
Terminal elimination half-life is 9 to 24 hours; clinically, it allows once or twice daily dosing.
Fecal: ~76% (primarily as unchanged drug); Renal: <1% (unchanged); Biliary: Not a major route; Metabolism via CYP3A4 to inactive metabolites eliminated fecally.
Primarily hepatic metabolism; less than 1% excreted unchanged in urine; metabolites excreted in urine (approximately 50%) and feces (approximately 36%) within 24 hours.
