CEFPROZIL vs CEFZIL
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.
Cefprozil inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting 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.
500 mg orally twice daily for 10 days; for uncomplicated skin infections, 250 mg twice daily or 500 mg once daily.

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."
1.2-1.5 hours in healthy adults; prolonged in renal impairment (e.g., up to 6-8 hours in severe renal failure)
Renal (primarily), approximately 60-70% unchanged in urine; biliary/fecal excretion accounts for <10%.
Renal: 80-91% unchanged in urine; biliary/fecal: minimal (<5%)
