Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ciprofloxacin is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase and topoisomerase IV, thereby preventing 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 to 1000 mg orally once daily for 7 to 14 days; extended-release tablet must be swallowed whole and administered with food.
600 mg intravenously once daily or 600 mg orally once daily.

Terminal elimination half-life is approximately 10-12 hours in patients with normal renal function, allowing twice-daily dosing; due to extended-release formulation, ciprofloxacin is released over 24 hours.
10-12 hours; prolonged in renal impairment
Renal excretion of unchanged drug accounts for approximately 40-50% of the dose; hepatic metabolism (glucuronidation, sulfation) produces active metabolites, and biliary/fecal elimination (via feces) accounts for 20-35% of the dose.
Renal: 60-80% unchanged; biliary/fecal: 10-20%
