PK Concentration Curve
Visualize predicted plasma concentration over time. See peak, trough, and steady-state accumulation for any dosing regimen.
PK Concentration Curve
Predicted plasma concentration over time using a one-compartment, first-order absorption and elimination model. All outputs are estimates based on assumed population-average parameters. Results are for educational reference only.
t½ 1.0 wk, F 89%, Vd 5 L, ka = 5x ke
Teal shading = predicted steady-state region (after ~5 half-lives). Dashed verticals = dose events.
Model: one-compartment, first-order absorption (SubQ) + first-order elimination. Defaults: Vd = 5 L, F = 70% (overridden per compound where published data exist), ka = 5x ke. Absolute concentration values depend on assumed Vd and F; treat the relative shape of the curve as more reliable than absolute numbers. Not a substitute for clinical PK modelling.
