RIFAXIMIN vs TIMENTIN IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Rifaximin is a non-aminoglycoside, semi-synthetic antibiotic derived from rifamycin that inhibits bacterial RNA synthesis by binding to the beta-subunit of bacterial DNA-dependent RNA polymerase, thereby blocking transcription.
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.
550 mg orally three times daily for 14 days for travelers' diarrhea; 200 mg orally three times daily for 3 days for irritable bowel syndrome with diarrhea; 400 mg orally three times daily for 7 days for hepatic encephalopathy.
3.1 g (ticarcillin 3 g + clavulanate 0.1 g) IV every 4 to 6 hours; maximum 18 g per day.

Clinical Note
moderateRifaximin + Digoxin
"The serum concentration of Digoxin can be increased when it is combined with Rifaximin."
Clinical Note
moderateRifaximin + Levofloxacin
"The serum concentration of Levofloxacin can be increased when it is combined with Rifaximin."
Clinical Note
moderateRifaximin + Estrone sulfate
"The serum concentration of Estrone sulfate can be decreased when it is combined with Rifaximin."
Clinical Note
moderateRifaximin + Tranilast
The terminal elimination half-life is approximately 1.8 to 2.5 hours in patients with normal hepatic function. Due to negligible systemic absorption, the half-life has limited clinical relevance; drug action is largely confined to the gastrointestinal tract.
Ticarcillin: ~1.2 hours; Clavulanate: ~1.0 hours. Prolonged in renal impairment (ticarcillin up to 15 hours in ESRD).
Rifaximin is primarily eliminated in feces as unchanged drug (>96% of an oral dose). Renal excretion is negligible (<0.4%). Biliary excretion is minimal due to poor systemic absorption.
Renal: ~70-80% of ticarcillin and ~60-70% of clavulanate excreted unchanged in urine within 6 hours. Biliary/fecal: Minor (<5%).
