🧪 Interactive 2D Mathematical Concepts Simulation

Give a drug once and its plasma concentration simply decays. Give it on a repeating schedule — the way almost every real prescription works — and the picture changes: each new dose lands on top of whatever is left of the previous ones, and the concentration climbs from dose to dose until it settles into a steady rhythm, oscillating between a steady-state peak and trough. This simulator draws that build-up in 3D as a live concentration curve with each individual dose marked along the timeline, so you can see directly how the dosing interval and the drug's half-life determine whether a regimen reaches a safe, stable plateau — or overshoots the therapeutic window entirely.
