Pseudoephedrine

What the body does with Pseudoephedrine, from the dose to the exit, as its Wikipedia drug infobox records it.

The clock, on a log scale

Each bar runs from the dose to about five half-lives, roughly when 97% of that molecule has been converted or cleared. The scale is logarithmic so minutes and days fit on one line.
