Half-Life and Accumulation Plotter
Visualize how repeated dosing accumulates and decays over time with an interactive, no-library chart.
Why this tool exists
This tool translates half-life language into a curve users can actually inspect and reason about.
Describe the dosing pattern
Common half-lives
Dose intervals
Course length
Accumulation readout
Peak after final dose
266.7
Immediate level after the last scheduled administration
Level one interval later
16.7
At 24 hours after the final dose
Accumulation factor
1.07
Approximate multiplier versus a single isolated dose
Time to 90% elimination
20 h
From the final dose in a simple first-order model
Level curve
A simplified accumulation model based on first-order decay.
Dotted vertical markers show scheduled dosing times. The x-axis is hours from the first dose.
Most of each dose clears before the next one
Model caveat
Best used for
- Understanding how interval changes affect accumulation
- Estimating peak and trough behavior over repeated doses
- Seeing how long levels linger after the last dose
Outputs
- Accumulation chart
- Peak and trough estimates
- Approximate time to 90% elimination after the last dose
