NITROFURANTOIN (MONOHYDRATE/MACROCRYSTALS) vs TICAR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nitrofurantoin is reduced by bacterial flavoproteins to reactive intermediates that inhibit bacterial cell wall synthesis, protein synthesis, and DNA/RNA synthesis. It is bacteriostatic at low concentrations and bactericidal at higher concentrations.
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.
100 mg orally twice daily for 5-7 days; 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: 20-60 minutes (average ~30 min) in patients with normal renal function; prolonged in renal impairment (e.g., CrCl <60 mL/min).
Terminal 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.
Renal excretion of unchanged drug accounts for approximately 40% of the dose; tubular reabsorption occurs. Biliary/fecal elimination is minimal (<5%).
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%).
