SEFFIN vs TAZICEF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
SEFFIN is a brand name for cefazolin, a first-generation cephalosporin antibiotic. It inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It is bactericidal against susceptible organisms.
Ceftazidime is a third-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3, leading to cell lysis and death.
1-2 g IV/IM every 6-8 hours; maximum 8 g/day.
2 g intravenously every 8 hours for serious infections; 1 g intravenously every 8 hours for uncomplicated infections.

Terminal elimination half-life is approximately 0.5-1 hour in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <10 mL/min).
2 hours (prolonged to 4-12 hours in renal impairment; anuria: 20-30 hours).
Primarily renal (80-90% unchanged) via glomerular filtration and tubular secretion; minor biliary excretion (<5%) and fecal elimination.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal <10%.
