Abstract:

Objective: To examine the effects of food on plasma concentration and bioavailability of fenofibrate administered as a sustained-release capsule.

Methods: Twenty-four healthy Korean volunteers were enrolled in a randomised, open-label, balanced, three-treatment, three-period, three-sequence, single oral dose, crossover pharmacokinetic study. A single dose of fenofibrate (250mg sustained-release capsule) was administered on three occasions - after overnight fasting, after consumption of a standard breakfast and after a high-fat breakfast. Serial blood samples were collected for the next 72 hours. Plasma fenofibric acid concentrations were measured by high-performance liquid chromatography, and pharmacokinetic parameters were calculated.

Results: The pharmacokinetic parameters were significantly affected by food intake. The high-fat breakfast affected the rate of absorption of fenofibrate more than the standard breakfast and fasted conditions. Specifically, the area under the plasma concentration-time curve from time zero to infinity (AUC_∞) and peak plasma concentration (C_max) increased 2.45-fold and 2.89-fold, respectively, between the fasted and standard-fed conditions (p < 0.01). In addition, the high-fat meal caused 3.34-fold and 3.82-fold increases compared with the fasted condition in AUC_∞ and C_max, respectively. A one-compartment open model with lag time successfully described the plasma concentrations of fenofibric acid.

Conclusion: In healthy volunteers, AUC_∞ and C_max of fenofibrate, when administered via sustained-release capsules immediately after the consumption of food, was increased significantly from the fasting conditions (p < 0.01). The greatest AUC_∞ and C_max occurred when the capsules were taken after a high-fat breakfast.
