Relative steady-state from a one-compartment model. Choose a dosing interval; Single is one dose with no repeat. Levels are multiples of a single dose’s peak, so the shape is what matters, not the number.

At this half-life and interval, levels reach 90% of steady state after about 13.3 h — roughly 0.6 days.

kₑ = ln(2) / t½
C(t) = Σ e^(−kₑ·(t − d·τ)) for d·τ ≤ t
C_ss = 1 / (1 − e^(−kₑ·τ))

This is a shape, not a prediction. The model assumes instant absorption, first-order elimination and identical repeat doses — none of which hold exactly in a body. Half-lives seeded from a compound are the values recorded in that entry’s references, and many are single-study estimates. For research use only; nothing here is a dosing schedule.
