We examined the pharmacokinetic behavior of 200 mg of ciprofloxacin administered intravenously to 32 volunteers whose renal function as measured by creatinine clearance ranged from 0 to 8.99 liters/h per 1.73 m2. Serum clearances (mean +/- standard deviation) were 26.8 +/- 5.7 and 15.4 +/- 4.3 liters/h per 1.73 m2 in normal and anephric volunteers, respectively. The half-life (mean +/- standard deviation) increased from 4.3 +/- 0.8 h in normal volunteers to 8.6 +/- 3.3 h in anephric volunteers. There was good correlation between normalized creatinine clearance and both normalized serum and renal clearance. The regression equation for serum clearance (CLS) versus creatinine clearance (CLCR) was CLS = 1.97 X CLCR + 13.23, where r = 0.697; for renal clearance versus creatinine clearance, the equation was CLR = 2.26 X CLCR, where r = 0.845. On the basis of these data, we recommend a maximum 50% reduction in dose when ciprofloxacin is instituted at a renal function of 1.2 to 1.8 liters/h per 1.73 m2 (20 to 30 ml/min per 1.73 m2). Because of the observed variation in ciprofloxacin half-life in our anephric volunteers, we also recommend that a schedule of administration every 12 h be maintained, even for patients without urine output. |
