Cetirizine

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

Quoted from the Wikipedia infobox, not yet written up by hand. The order is the usual order of events, not a measured schedule.

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.
