CEFUROXIME vs CEFZIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking and 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 twice daily; 750 mg-1.5 g IV/IM every 8 hours for moderate infections; 1.5 g IV/IM every 8 hours for severe infections.
500 mg orally twice daily for 10 days; for uncomplicated skin infections, 250 mg twice daily or 500 mg once daily.

Terminal elimination half-life is 1.2 hours in adults with normal renal function (increased to 15-22 hours in severe renal impairment [CrCl <10 mL/min], requiring dose adjustment).
Clinical Note
moderateCefuroxime + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefuroxime."
Clinical Note
moderateCefuroxime + Cimetidine
"Cefuroxime can cause a decrease in the absorption of Cimetidine resulting in a reduced serum concentration and potentially a decrease in efficacy."
Clinical Note
moderateCefuroxime + Methantheline
"Cefuroxime can cause a decrease in the absorption of Methantheline resulting in a reduced serum concentration and potentially a decrease in efficacy."
Clinical Note
moderate1.2-1.5 hours in healthy adults; prolonged in renal impairment (e.g., up to 6-8 hours in severe renal failure)
Renal excretion of unchanged drug accounts for 80-90% of elimination via glomerular filtration and tubular secretion; biliary/fecal excretion is minimal (<10%).
Renal: 80-91% unchanged in urine; biliary/fecal: minimal (<5%)

Cefuroxime + Olanzapine
"Cefuroxime can cause a decrease in the absorption of Olanzapine resulting in a reduced serum concentration and potentially a decrease in efficacy."
