NITROFURANTOIN (MONOHYDRATE/MACROCRYSTALS) vs TIMENTIN IN PLASTIC CONTAINER
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.
Timentin is a combination of ticarcillin, a penicillin-class beta-lactam antibiotic, and clavulanate, a beta-lactamase inhibitor. Ticarcillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), while clavulanate irreversibly inhibits beta-lactamases, preventing degradation of ticarcillin.
100 mg orally twice daily for 5-7 days; for uncomplicated urinary tract infection.
3.1 g (ticarcillin 3 g + clavulanate 0.1 g) IV every 4 to 6 hours; maximum 18 g per day.

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).
Ticarcillin: ~1.2 hours; Clavulanate: ~1.0 hours. Prolonged in renal impairment (ticarcillin up to 15 hours in ESRD).
Renal excretion of unchanged drug accounts for approximately 40% of the dose; tubular reabsorption occurs. Biliary/fecal elimination is minimal (<5%).
Renal: ~70-80% of ticarcillin and ~60-70% of clavulanate excreted unchanged in urine within 6 hours. Biliary/fecal: Minor (<5%).
