CIPRO XR vs CIPROFLOXACIN EXTENDED RELEASE
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.
Inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, preventing DNA replication, transcription, repair, and recombination.
500 mg to 1000 mg orally once daily for 7 to 14 days; extended-release tablet must be swallowed whole and administered with food.
500-1000 mg orally once daily for 7-14 days; extended-release tablet must be taken whole with a meal.

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.
Terminal elimination half-life approximately 11 hours, ranging from 10-14 hours in patients with normal renal function. Prolonged in renal impairment; requires dose adjustment.
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.
Primarily renal excretion (50-70% unchanged drug via glomerular filtration and tubular secretion); 15-25% metabolized; 20-35% fecal elimination via biliary secretion and intestinal epithelium.
