What we built.
Drug-PIN began in 2018 as an attempt to write an expert’s reasoning down: the interaction rules, the organ function thresholds, the geriatric lists, the enzyme matrix, all set down as an explicit calculation that holds from one patient to the next.
The ambition is simple to state and hard to reach: that every patient on a complex therapy gets the same quality of review as the one who happens to be seen by a specialist. The same decision, available everywhere, and made with the whole picture in front of you.
That is also why the method was published before it was sold. A calculation that cannot be inspected has no place in a clinic, and the comparison that mattered most was the one against the expert doing it by hand.
