HMG-CoA reductase inhibitors decrease serum cholesterol by inhibiting hepatic cholesterol synthesis, but their influence on biliary lipids is not well characterized. In the present study Pravastatin (80 mg) was administered as a single oral dose to 10 patients with external bile fistula, after 1 week of interruption of the enterohepatic circulation, in order to assess the effect of inhibition of hepatic cholesterol synthesis on biliary lipids in conditions of stimulated bile acid synthesis. Bile was collected every hour for 12 h. On the day before, the same procedure was applied with a placebo, and collected bile used as control. Pravastatin decreased both bile acid and phospholipid concentration to about 60% of basal values; this change was still significant after 10 h. Cholesterol concentration was also decreased to about 70% of basal values, but this change was significant only from the 5th to the 7th h. The per cent of cholic and chenodeoxycholic acid was not affected by the drug, but the ratio of glyco- to tauroconjugated bile acids was decreased to about half the initial values. Bilirubin concentration exhibited a late increase, suggesting a reduction in the bile flow. These results suggest that, in patients with interrupted enterohepatic circulation, biliary excretion of bile acids can be largely dependent on hepatic cholesterol synthesis.
