NITROFURANTOIN vs TRIMPEX 200
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nitrofurantoin is reduced by bacterial flavoproteins to reactive intermediates that inactivate or inhibit bacterial ribosomal proteins, DNA, RNA, and metabolic enzymes, leading to bacterial cell death.
Trimethoprim inhibits bacterial dihydrofolate reductase, blocking the conversion of dihydrofolic acid to tetrahydrofolic acid, thereby inhibiting bacterial DNA synthesis.
100 mg orally twice daily for 5-7 days (uncomplicated UTI); 50-100 mg orally four times daily for 7 days (symptomatic uncomplicated UTI). Extended-release: 100 mg orally twice daily for 7 days.
200 mg orally once daily, or 100 mg orally twice daily.

Clinical Note
moderateNitrofurantoin + Norfloxacin
"The therapeutic efficacy of Norfloxacin can be decreased when used in combination with Nitrofurantoin."
Clinical Note
moderateNitrofurantoin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Nitrofurantoin."
Clinical Note
moderateNitrofurantoin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Nitrofurantoin."
Clinical Note
moderateNitrofurantoin + Rolapitant
Normal renal function: 20-60 minutes; impaired function: prolonged up to 1-2 hours, clinically significant due to urinary concentration requirement
Terminal elimination half-life is 8-10 hours in adults with normal renal function; prolonged to 20-30 hours in renal impairment (CrCl <30 mL/min), requiring dose adjustment.
Renal: ~40% unchanged via glomerular filtration and tubular secretion, biliary/fecal: <1%
Renal excretion of unchanged drug accounts for approximately 60-80% of elimination, with an additional 10-20% as hepatic metabolites excreted in bile and feces.
