Saxenda / Victoza. ~13 hour half-life, so it is daily — a useful contrast to weekly semaglutide.
The default row models 1.80 mg as a subcutaneous dose, daily (ed), for 8 weeks.
Also called Victoza, Lira, Liraglutide.

On that default row the model counts 56 doses. Steady state is about day 2.7. Washout runs to about day 3.2. In the last interval the peak is 2.49 mg and the trough is 1.31 mg, a swing of 47%.
A half-life of 0.5d means each dose has mostly cleared before the next daily dose, so the line is a row of spikes.
Ozempic has a half-life of 7d against 0.5d on this page.
