KETEK vs TIMENTIN IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Telithromycin binds to the 50S subunit of bacterial ribosome, inhibiting protein synthesis by blocking peptide chain elongation.
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.
Telithromycin 800 mg orally once daily for 7-10 days.
3.1 g (ticarcillin 3 g + clavulanate 0.1 g) IV every 4 to 6 hours; maximum 18 g per day.

Terminal half-life (t½) is 9.8–10.6 hours in young healthy adults, allowing once-daily dosing. In elderly or severe hepatic impairment, t½ may be prolonged.
Ticarcillin: ~1.2 hours; Clavulanate: ~1.0 hours. Prolonged in renal impairment (ticarcillin up to 15 hours in ESRD).
Primarily fecal (≈70%) via biliary excretion of unchanged drug; renal excretion accounts for ≈13% (mostly unchanged), with additional minor metabolism (<30%).
Renal: ~70-80% of ticarcillin and ~60-70% of clavulanate excreted unchanged in urine within 6 hours. Biliary/fecal: Minor (<5%).
