Hyperlipoproteinemic patients with raised pre-.beta.- or pre-.beta.- and .beta.-lipoprotein fractions showed a significant (P < 0.001) increase in binding of fentanyl to whole plasma, compared with normal subjects. The presence of chylomicra had no significant effect on binding. In patients with chronic renal failure, a correlation of probability (P < 0.07) was found between percent binding and concentrations of pre-.beta.-lipoprotein (P = 0.001), serum albumin (P = 0.0101), total protein minus albumin (P = 0.0576) and .beta.-lipoprotein (P = 0.0625). There was no significant correlation of binding with elevation of .alpha.- or .gamma.-globulins, with urea or creatinine concentrations, or with age or sex (P .gtoreq. 0.223). The magnitude of changes in the free fraction found in these patients should not produce a clinical effect as the total distribution volume of fentanyl exceeds 200 l.
