title: Ciprofloxacin concentrations in tonsils following a single intravenous infusion.
abstract: Penetration of ciprofloxacin into human tonsils was studied following an intravenous infusion of 200 mg over 15 minutes to adult humans undergoing tonsillectomy. Samples were taken one-and-a-half to four hours after dosing. Generally, tissue levels exceeded corresponding serum concentrations by 50% (range of intraindividual ratios between tonsil and serum concentrations 100% to 288%). Ciprofloxacin distribution was homogeneous and independent of sampling time.
