Pharmacology Is someone familiar with differential equations?

I need to write a function that calculates plasma concentration of the active metabolite of a prodrug after chronic dosing. I already did the single dosing part so we can like discuss it on discord.

Here's the source for the algorithm you seek:

Differential Equations

Are you seeking information on how to program in a particular computer language or mathematics?

In a nutshell :

If you track a variable with respect to instantaneous vector data, the then function is proportional.
If you track the same data with the ratio above and below that data path then the function is differential.
There is a data tracking function even more precise known as integral, but that is beyond a TL/DR discussion.
