CEFPROZIL vs ZINACEF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefprozil, a second-generation cephalosporin, exerts bactericidal activity by binding to penicillin-binding proteins (PBPs) and inhibiting bacterial cell wall synthesis, leading to cell lysis.
Cefuroxime, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
250-500 mg orally every 12 hours for 10 days; for pharyngitis/tonsillitis: 500 mg orally every 24 hours for 10 days.
750 mg IV/IM every 8 hours; for severe infections: 1.5 g IV every 8 hours; for life-threatening infections: 1.5 g IV every 6 hours

1.2-1.4 hours in adults with normal renal function; prolonged to 5-6 hours in severe renal impairment (CrCl <30 mL/min).
Clinical Note
moderateCefprozil + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefprozil."
Terminal elimination half-life: 1.5-2 hours in adults with normal renal function; prolonged to 2.5-3.5 hours in elderly and up to 48 hours in end-stage renal disease.
Renal (primarily), approximately 60-70% unchanged in urine; biliary/fecal excretion accounts for <10%.
Renal: 80-95% unchanged via glomerular filtration and tubular secretion; biliary: 5-10% excreted in feces; fecal: negligible.
