Online graphing calculator for dosages?

[DaveC426913]

TL;DR

Interested in the curves of medical dosages, is there a graph program?

I've become fascinated with how repeat doses of medications affect the body's level of the drugs (see sample diagram).

Is there some sort of online software grapher that takes params such as half-life and plots a graph?

I guess this is exactly what Wolphram Alpha does isn't it? I tried it once but it's over my head without a bit of a tutorial.

A quick side note. I do not know of an app, BTW.

Half life of drugs is important but there are other biochemical "parameters" that may affect the dose response curve, or things like drug titer
Example Eliquis: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3684191/
As the titer is repeatedly increased with repeating doses, a threshold is eventually reached where some increased carryover between doses flattens out the the response curve. I guess you could consider it to be an extended half life.

The point being: for an app to be reliable there may be a need for complex set of program run-time parameters for handling exceptions -- like drugs that do interesting things when taken over long periods. @Godot_ can give you more information.

Thanks, yeah. More an academic interest; there's certainly too many factors that affect uptake and expulsion to make any practical use of it.
