Work out steady state time instantly with clear inputs, formula shown and shareable results.
Calculates how long repeated dosing takes to approach steady state, since accumulation follows the same exponential as elimination.
Time to steady state
Fraction of steady state = 1 - 0.5^(number of half-lives); solving gives half-lives = ln(1 - fraction) / ln 0.5

It reaches about 97% of steady state, which is within measurement error of the plateau.
Yes, with a loading dose, which fills the volume of distribution immediately.
