Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ketoconazole, an imidazole antifungal agent, inhibits fungal cytochrome P450 14α-demethylase (CYP51), preventing the conversion of lanosterol to ergosterol, an essential component of fungal cell membranes. This disrupts membrane integrity and function.
SANSAC is a synthetic peptide that acts as a selective antagonist of the vasopressin V2 receptor, thereby inhibiting water reabsorption in the renal collecting ducts and promoting aquaresis.
Apply to wet hair, lather, and leave on for 3-5 minutes before rinsing. Use twice weekly for 4 weeks, then as needed to control dandruff.
For adult patients, the recommended dose of SANSAC is 500 mg administered orally twice daily with or without food.

Terminal elimination half-life is biphasic: initial 2 hours, terminal 8 hours (range 6-10 hours). After topical application, systemic absorption is minimal, resulting in an effective half-life of 72-96 hours in skin.
The terminal elimination half-life is approximately 12-15 hours in healthy adults, with clinical significance for once-daily dosing. In patients with renal impairment (CrCl <30 mL/min), the half-life may be prolonged up to 24-36 hours, requiring dose adjustment.
Primarily fecal (57%) via biliary excretion as unchanged drug and metabolites; renal excretion accounts for approximately 13% (2-4% unchanged).
Renal excretion accounts for approximately 60-70% of the administered dose as unchanged drug, with an additional 10-15% as metabolites. Fecal elimination constitutes 10-15% mainly via biliary secretion. Less than 5% is eliminated via other routes.
