The view plots an estimated level curve from your logged doses and the compound’s published half-life.
It shows accumulation, dose overlap, decay, and the dip a missed dose creates.
The curve is an estimate from population values and transparent models — not a measurement of your blood.
Two pharmacokinetic models are available for different curve shapes.
It is only as good as the log, which is why accurate dose timing matters.
The medication-level view plots an estimated level curve from the doses you have logged and the compound's published half-life — showing accumulation, overlaps, and decay over time.
In plain terms: it turns "half-life = 7 days" into a picture of what your own logged doses add up to.
What it computes
Using the half-life of the compound and the timing of your logged doses, the app models the rising-and-falling curve — including accumulation toward steady-state when doses repeat. Two models are available for different pharmacokinetic shapes.
What the curve shows
The estimated level now and over time.
How doses stack when they overlap.
The dip a missed or late dose creates.
For a stack, overlaid curves for multiple compounds.
Its honest limits
The curve is an estimate, not a measurement. It uses population half-life values and transparent models — real individual pharmacokinetics vary with route, formulation, and physiology. The app labels it "estimated level" deliberately; it is a model of the concentration curve, not your actual blood level. For compounds with a PK-PD disconnect — where the drug clears the blood but its effect lingers — it does not claim to represent *effect* at all.
In plain terms: it is an honest model of the level trend, not a lab reading of your blood.
Why it beats a static number
"Half-life = 7 days" is a fact; a curve built from *your* logged doses shows what that fact means for *your* timeline — which is the useful part. It is only as good as the log, which is why accurate dose logging matters.
The curve is an educational model, not medical advice or a measurement. Open Zyra Labs to see it build from your log.
Frequently asked
Are the medication-level curves measurements?
No. They are estimates computed from the doses you log and published half-life values, using transparent pharmacokinetic models. They are educational approximations of the level curve, not measurements of your actual blood levels.
What does the curve actually show?
The estimated level now and over time, how doses stack when they overlap, the dip a missed or late dose creates, and — for a stack — overlaid curves for multiple compounds.
Why can the curve be wrong for me?
It uses population half-life values and general models. Real individual pharmacokinetics vary with route, formulation, and physiology, so the curve is a model of the concentration trend, not your actual measured level.
