Method
How the rows were made
- A deterministic parser reads recorded FDA-label excerpts for named enzymes and transporters.
- A mention is admitted only when the stored excerpt contains the recorded counterparty, allowing letter-case differences only.
- Every admitted mention is grouped by exact medicine slug, recorded counterparty spelling, and exact role. A missing role remains NOT_RECORDED rather than being assigned to another group.
- Each sentence carries the exact source version and effective date when recorded; the API serializes null and the page says not recorded when either is absent.
- The API paginates groups. Within each returned group, sentences is the complete untruncated list used by the three polarity counts.
Limits
Read these before using a row
- A recorded role is a mechanistic statement copied from a descriptive label section. It is not a clinical interaction, and nothing in this dataset describes what happens when a person is exposed to two medicines at once.
- This dataset holds no relation between one medicine and another. Counts are per counterparty; the medicines naming a counterparty are listed with their sentences and are never paired, ranked against each other or compared.
- ICH M12 states that no potency classification system exists for transporters or for non-CYP enzymes, so no strong, moderate or weak vocabulary is applied to any counterparty here. The tallies count records, not strength.
- A counterparty with a high count is one that labels document often. Documentation frequency is not importance: US labelling asks for some enzymes to be characterised far more routinely than others, and that requirement is part of what these counts measure.
- 40.1% of admitted mentions carry no role. The sentence named more than one role and the parser left the question open rather than attaching a guess, so a role tally is a count of sentences that settled the question, not of medicines for which it is settled.
- Recorded spellings are counted separately and never merged. P-GP, PGP and P-GLYCOPROTEIN are three entries in this dataset because they are three strings in the corpus; whether they name one thing is a question for a person, and prefix relationships are reported as questions rather than resolved.
- 9088 of 9855 records name no enzyme or transporter at all. That is an absence of recorded text in the sources fetched for those records. It is neither reassurance nor alarm about the medicines concerned.
- 20358 of 20358 admitted mentions come from records the deterministic label parser produced, where no person chose the value or wrote its measurement context. The sentence is stored with each one so a reader can check it.
- The uniform reference for concentration allocates the same 20358 mentions over the same 36 counterparties by chance. Labels are not written that way, so the reference shows only that the observed spread is not a consequence of how many mentions there are.
- The public rows enumerate documentation about one medicine and one named counterparty. They never create medicine-to-medicine pairs and cannot answer whether two medicines interact.
- A NOT_RECORDED role or polarity remains unresolved. It is never folded into an assertion or a denial.
- Each returned group includes every admitted source sentence for checking, but the full source document remains authoritative.
