LEVOFLOXACIN IN DEXTROSE 5% IN PLASTIC CONTAINER vs ZAGAM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Levofloxacin is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby inhibiting DNA replication and transcription.
Sparfloxacin, a fluoroquinolone antibiotic, inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby blocking DNA replication and transcription.
500 mg or 750 mg intravenously once daily. Infusion over 60-90 minutes.
600 mg intravenously once daily or 600 mg orally once daily.

6-8 hours in patients with normal renal function (creatinine clearance >50 mL/min); increases to 20-48 hours in severe renal impairment (CrCl <20 mL/min); clinically relevant for dosing interval adjustment.
10-12 hours; prolonged in renal impairment
Renal: ~87% of dose excreted unchanged in urine via glomerular filtration and tubular secretion; biliary/fecal: <5% eliminated as unchanged drug and metabolites; <4% recovered in feces.
Renal: 60-80% unchanged; biliary/fecal: 10-20%
