CORDRAN N vs KETEK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cordran N contains flurandrenolide, a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive actions by inducing phospholipase A2 inhibitory proteins (lipocortins) and modulating gene expression; neomycin is an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit.
Telithromycin binds to the 50S subunit of bacterial ribosome, inhibiting protein synthesis by blocking peptide chain elongation.
Apply sparingly to affected area 2-3 times daily. Use for no longer than 2 weeks.
Telithromycin 800 mg orally once daily for 7-10 days.

Approximately 1-2 hours. Short half-life consistent with topical use; systemic exposure minimal with proper application.
Terminal half-life (t½) is 9.8–10.6 hours in young healthy adults, allowing once-daily dosing. In elderly or severe hepatic impairment, t½ may be prolonged.
Primarily renal (biliary/fecal minimal). Unchanged drug and glucuronide metabolites excreted in urine.
Primarily fecal (≈70%) via biliary excretion of unchanged drug; renal excretion accounts for ≈13% (mostly unchanged), with additional minor metabolism (<30%).
