KETEK vs UCEPHAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Telithromycin binds to the 50S subunit of bacterial ribosome, inhibiting protein synthesis by blocking peptide chain elongation.
UCEPHAN (eculizumab) is a monoclonal antibody that binds to complement protein C5, inhibiting its cleavage to C5a and C5b, thereby preventing the formation of the membrane attack complex (MAC) and terminal complement-mediated cell lysis.
Telithromycin 800 mg orally once daily for 7-10 days.
500 mg orally every 12 hours or 250 mg orally every 8 hours.

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.
Terminal elimination half-life is 2.1 ± 0.5 hours in adults with normal renal function; prolonged to 20–50 hours in severe renal impairment (CrCl <10 mL/min).
Primarily fecal (≈70%) via biliary excretion of unchanged drug; renal excretion accounts for ≈13% (mostly unchanged), with additional minor metabolism (<30%).
Approximately 70–80% of an administered dose is eliminated unchanged in urine via glomerular filtration and tubular secretion; the remainder (20–30%) is eliminated via biliary/fecal routes, with <5% as metabolites.
