Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fosfomycin inhibits bacterial cell wall synthesis by inactivating the enzyme UDP-N-acetylglucosamine enolpyruvyl transferase (MurA), which catalyzes the first step of peptidoglycan biosynthesis.
Ticarcillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It is a time-dependent bactericidal agent.
3 g orally once as a single dose for uncomplicated urinary tract infection.
3 g IV every 4 hours for pseudomonal infections; 3 g IV every 6 hours for less severe infections.

Terminal elimination half-life is 5.7 hours (range 3-8 hours) in patients with normal renal function; approximately 50 hours in end-stage renal disease (CrCl <10 mL/min).
Clinical Note
moderateTicarcillin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ticarcillin."
Clinical Note
moderateTicarcillin + Mycophenolic acid
"The serum concentration of the active metabolites of Mycophenolic acid can be reduced when Mycophenolic acid is used in combination with Ticarcillin resulting in a loss in efficacy."
Clinical Note
moderateTicarcillin + Plicamycin
"The serum concentration of Plicamycin can be decreased when it is combined with Ticarcillin."
Clinical Note
moderateTerminal elimination half-life is approximately 1.2 hours in adults with normal renal function. In renal impairment, half-life may extend to 15-20 hours; dose adjustment required for CrCl <60 mL/min.
Primarily excreted unchanged in urine via glomerular filtration (approximately 90% of absorbed dose within 24-48 hours); small amount (approximately 10%) excreted in feces via biliary elimination.
Ticarcillin is primarily excreted unchanged in urine via glomerular filtration and tubular secretion, accounting for 90-95% of the dose. Biliary/fecal excretion is minimal (<5%).
