The Effect of a High-Fat Breakfast on the Pharmacokinetics of Moxidectin in Healthy Male Subjects: A Randomized Phase I Trial
The objective of this study was to assess the effect of a high-fat meal on the pharmacokinetics of moxidectin. Healthy male subjects were randomized to receive single oral 8 mg doses of moxidectin after an overnight fast or high-fat breakfast. In fasted subjects ( N = 27), mean [SD] parameters were...

AbstractList | The objective of this study was to assess the effect of a high-fat meal on the pharmacokinetics of moxidectin.

In fasted subjects (N = 27), mean [SD] parameters were C sub(max): 58.9 [12.5] ng/mL; t sub(max): 3.7 [1.5] h; area under concentration-time curve (AUC): 3,387 [1,328] ng/h/mL; lambda sub(z)/F: 2,829 [1,267] L; CL/F: 2.76 [1.28] L/h; and t sub(1/2): 784 [347] h.
