What is the bioavailability of Brexpiprazole?

Explanation:
Bioavailability is the fraction of an administered dose that reaches the systemic circulation unchanged. For brexpiprazole, the oral form is absorbed very well, with essentially complete bioavailability—reported as greater than 99%. This means almost the entire oral dose becomes available to exert effect in the body, with minimal loss to first-pass metabolism or incomplete absorption. In practice, that makes oral dosing highly predictable in terms of systemic exposure. The other options would reflect substantial loss before reaching circulation, which isn’t consistent with brexpiprazole’s pharmacokinetic profile.
