PepScribe Half-Life

PepScribe Half-Life shows how much of a medication or supplement remains in the body over time from its elimination half-life. Give the half-life in hours (from the product's published information) and, if you like, the dose and the time between doses. It draws the levels over time, tells you how long until about 97% is cleared (five half-lives), how much is left after a day and after a week, and for repeated doses how levels build up and when they reach steady state. The result is a card with a curve that draws in, half-life markers after the last dose, a steady-state band for repeated doses, and a scrubber you can drag or step with the arrow keys to read any moment. PepScribe Half-Life uses a simplified one-compartment model for education; real levels vary with the person, the formulation and absorption. It does not suggest a dose, a dosing interval, or when it is safe to take something else. The numbers you enter are used to draw the chart and are not stored.
