PK Desk - paste a concentration-time profile, get the NCA reviewed and the regimen it supports

Clean

Paste a pharmacokinetic concentration-time table - one subject or many, any mass-per-volume unit, BLQ values as the lab reported them - and the browser computes the non-compartmental analysis at once: Cmax, Tmax, AUC by linear-up/log-down trapezoid, the terminal phase chosen by adjusted R-squared, half-life, AUC to infinity and the fraction extrapolated, MRT, clearance and volume, with every acceptance criterion checked and flagged. The profile lane reviews that analysis: phases seen in the curve, each parameter graded reliable, caution, unreliable or not estimable, findings with recommendations, sampling advice, and a verdict of reportable, reportable with caveats or not reportable that the page re-derives. The regimen lane takes the same profile plus a proposed dose and interval and predicts steady state by superposition - Cmax,ss, Cmin,ss, Cavg,ss, accumulation, time to steady state, alternatives - judged against your target window.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
