title: Pharmacokinetics of single dose intravenous ciprofloxacin in patients undergoing gastrointestinal surgery.
abstract: The pharmacokinetics of single dose intravenous ciprofloxacin in patients undergoing gastrointestinal surgery (100 mg, n = 8; 200 mg n = 18) have been studied. Following 100 mg therapeutic serum levels were maintained for approximately 40 min only and tissue concentrations were frequently less than 0.15 mg/kg. 200 mg maintained therapeutic serum levels for at least 150 min and produced mean concentrations in fat, muscle, peritoneum and gut wall of 1.04, 1.94, 1.59, and 3.39 mg/kg respectively. 200 mg iv ciprofloxacin would appear to provide adequate serum and tissue concentrations for at least 150 min.
