Understanding Half-Life Visualization

Peak

Maximum concentration after dosing (Cmax)

Steady State

Reached after ~5 half-lives of repeated dosing

Accumulation

With frequent dosing, levels build up over time

Clinical Insight: A peptide is ~97% eliminated after 5 half-lives. For a peptide with a 9-day half-life (like Tesofensine), this means ~45 days for near-complete clearance. This visualization helps plan dosing frequency and understand "wash-out" periods.

Half-Life Notes:

Half-life (t½) is the time for 50% elimination. After 5 half-lives (~97% cleared), consider fully eliminated.

Data Source

Pharmacokinetic data from published clinical trials, drug databases (DrugBank, PubChem), and peer-reviewed pharmacology literature. Half-life values represent population averages; individual variation exists.
