How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What acts on it

  1. Armodafinil had higher dose-normalized late exposure than racemic modafinil despite similar approximately 13-hour terminal half-lives in the pooled single-dose studies.

    S-modafinil disappears more rapidly from plasma. A pooled analysis of three single-dose studies found similar terminal half-lives, approximately 13 hours, for racemic modafinil and armodafinil, but higher dose-normalized late exposure with armodafinil. The racemate's early decline reflected removal of its faster-cleared S component. A single terminal half-life therefore conceals meaningful differences in the exposure curve. These data do not establish universal clinical superiority of either formulation. [Comparative human pharmacokinetics](https://pubmed.ncbi.nlm.nih.gov/19663523/)
