The distribution of antibiotics into target tissues is a crucial factor in therapeutic efficacy. To estimate the availability of systemically administered vancomycin to the interstitial fluid in the lung, we have used a sheep model with a chronic pulmonary lymph fistula to collect simultaneously series of plasma and pulmonary lymph specimens during a 6-h period after an intravenous dose of vancomycin (7 mg/kg). After a minor delay in transit from blood to lymph, vancomycin was completely distributed to pulmonary lymph with a ratio of free drug in lymph to free drug in plasma of 0.9. This suggests that vancomycin is an excellent choice for treating pulmonary infections by susceptible organisms.
