Half-life (h)

Absorption rate ka (/h)

Oral dose (absorption phase)

After a dose, drug concentration rises as it absorbs, then falls exponentially as the body clears it. The half-life sets the decline; the goal is to stay inside the therapeutic window — high enough to work, low enough to be safe. Educational tool, not medical advice.

Data Inspector

Peak concentration12.02 mg/L

Time to peak1.9 h

Elimination rate ke0.173 /h

Governing equation

C (t) = \frac{500}{30} e^{- 0.173 t}, t_{1/2} = \frac{ln 2}{k _{e}} = 4 h

Reading this result: Absorption (ka 1.2/h) is much faster than elimination, so the drug reaches its peak quickly (about 1.9 h) and the curve then tracks the 4-hour half-life on the way down.

About this simulation

The full Pharmacokinetics tool models an enzyme reaction with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
