RESUMO

The relationship between serum and saliva chloramphenicol (CAP) concentrations was evaluated in 27 paired specimens collected from 20 hospitalized patients during therapy with the drug. A significant (R = 0.80, P < 0.001) but variable relationship was found to exist. Serum protein binding of CAP was also evaluated (43.7 ± 5.7% bound; N = 24). Differences in CAP binding did not apparently account for a significant portion of the variability in the observed saliva/serum CAP concentration ratios. The degree of variation observed indicated that saliva CAP concentrations could not be relied upon for the prediction of serum CAP concentrations.
