NEO-FRADIN vs TIMENTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Neomycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting bacterial protein synthesis. It also disrupts bacterial cell membrane integrity.
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.
50-100 mg/kg/day orally in 3-4 divided doses. Maximum 3 g/day.
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.

2-3 hours in normal renal function; prolonged to 24-30 hours in anuria or severe renal impairment; no significant change in hepatic disease.
Ticarcillin: ~1.1 hours; clavulanate: ~1.0 hours. Prolonged in renal impairment (CrCl <10 mL/min: ticarcillin half-life ~13 hours).
Renal: >90% unchanged drug via glomerular filtration, with small amount reabsorbed; biliary/fecal: <2%.
Renal: 60-80% ticarcillin and 50-70% clavulanate excreted unchanged in urine via glomerular filtration and tubular secretion. Fecal: minimal.
