Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibition of protein synthesis in susceptible bacteria.
Timentin is a combination of ticarcillin, a penicillin-class antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), and clavulanic acid, a beta-lactamase inhibitor that irreversibly inhibits a wide range of beta-lactamase enzymes, thereby preventing degradation of ticarcillin and extending its spectrum to include beta-lactamase-producing organisms.
100 mg intravenously every 12 hours.
3.1 g (ticarcillin 3 g + clavulanic acid 0.1 g) IV every 4-6 hours; for moderate infections, 3.1 g IV every 6 hours; for severe infections, 3.1 g IV every 4 hours.

Terminal elimination half-life is 2.5-3 hours in adults with normal renal function; increased to up to 10-15 hours in severe renal impairment (CrCl <30 mL/min). Clinically, this supports 8-hourly dosing intervals in normal renal function, with extended intervals in renal impairment.
Ticarcillin: ~1.1 hours; clavulanate: ~1.0 hours. Prolonged in renal impairment (CrCl <10 mL/min: ticarcillin half-life ~13 hours).
Renal excretion accounts for 90-100% of elimination, primarily as the parent drug via glomerular filtration and tubular secretion. Urinary excretion: 90-100% unchanged. Fecal/biliary: negligible (<2%).
Renal: 60-80% ticarcillin and 50-70% clavulanate excreted unchanged in urine via glomerular filtration and tubular secretion. Fecal: minimal.
