CEFPROZIL vs CEFTRIAXONE
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 is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
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 24 hours; maximum 4 g/day.

Clinical Note
moderateCeftriaxone + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ceftriaxone."
Clinical Note
moderateCeftriaxone + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Ceftriaxone."
Clinical Note
moderateCefprozil + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefprozil."
Clinical Note
moderateWarfarin + Ceftriaxone
1.2-1.4 hours in adults with normal renal function; prolonged to 5-6 hours in severe renal impairment (CrCl <30 mL/min).
Terminal half-life: 5.8-8.7 hours in adults; prolonged to 12-24 hours in neonates and 30-90 hours in severe renal impairment.
Renal (primarily), approximately 60-70% unchanged in urine; biliary/fecal excretion accounts for <10%.
Renal (33-67% unchanged) and biliary (up to 40%) with fecal elimination. In neonates, renal excretion is lower (~20%).
