The pharmacokinetics of tobramycin in adolescents or young adults with cystic fibrosis and in age-matched controls were prospectively compared. Patients with CF had a higher tobramycin total body clearance (121.2 +/- 14.2 ml/min/1.73 m2) than did controls (102.2 +/- 18.9 ml/min/1.73 m2, P less than 0.05). This was not associated with a higher glomerular filtration rate (iothalamate total body clearance 147.5 +/- 29.2 ml/min/1.73 m2 in patients vs 142.9 +/- 33.3 ml/min/1.73 m2 in controls) or a lower binding of gentamicin to serum proteins (14.3% +/- 2.6% in patients vs 17.4% +/- 3.8% in controls). Tobramycin renal clearance was not significantly different in the two groups (89.5 +/- 17.9 ml/min/1.73 m2 in patients vs 81.0 +/- 15.8 ml/min/1.73 m2 in controls). In the control group, tobramycin total body and renal clearances were highly correlated with iothalamate total body clearance (r = +0.95 and +0.88, P less than 0.01). In patients with cystic fibrosis, the correlation was not significant (r = +0.56, P greater than 0.05 for total body clearance, and r = 0.32, P greater than 0.1 for renal clearance). There was no significant difference in volume of distribution normalized to body surface area or in half-life of elimination. The higher tobramycin total body clearance without an increase in renal clearance, and the lower correlation with glomerular filtration rate indicate that an extrarenal clearance pathway might play a significant role in the elimination of tobramycin from the serum of patients with cystic fibrosis.
