Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Trimethoprim inhibits bacterial dihydrofolate reductase, blocking the conversion of dihydrofolic acid to tetrahydrofolic acid, thereby inhibiting bacterial DNA synthesis.
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.

Terminal elimination half-life is 8-10 hours in adults with normal renal function; prolonged to 20-30 hours in renal impairment (CrCl <30 mL/min), requiring dose adjustment.
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).
Renal excretion of unchanged drug accounts for approximately 60-80% of elimination, with an additional 10-20% as hepatic metabolites excreted in bile and feces.
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.
