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.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and 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.
1-2 g IV/IM every 12-24 hours; maximum 4 g/day.

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 is 5.8-8.7 hours in adults with normal renal and hepatic function. In neonates, half-life is prolonged (up to 16 hours). In patients with renal impairment, half-life increases to 12-18 hours; in hepatic impairment, it may be 15-20 hours. Dose adjustment is not typically required unless both renal and hepatic impairment are present.
Renal (primarily), approximately 60-70% unchanged in urine; biliary/fecal excretion accounts for <10%.
Ceftriaxone is eliminated 33-67% unchanged in urine via glomerular filtration and tubular secretion, and the remainder is excreted in feces (primarily as microbiologically inactive metabolites) via biliary secretion. Biliary excretion accounts for approximately 35-45% of total clearance.
