CEFOTETAN AND DEXTROSE IN DUPLEX CONTAINER vs KEFLEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), resulting in cell lysis and death.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
1 to 2 g intravenously every 12 hours for 5 to 10 days. For severe infections, 2 g intravenously every 12 hours.
250-500 mg orally every 6 hours; maximum 4 g/day.

Terminal elimination half-life 3-4 hours in normal renal function; prolonged in renal impairment (e.g., up to 13 hours in severe renal failure).
0.5–1.2 hours in patients with normal renal function (CrCl >50 mL/min); prolonged to >20 hours in ESRD.
Primarily renal (unchanged drug) ~88%; minor biliary/fecal ~6-9%.
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
