Primes¶
- Potentiation
- Not equivalent to drug-drug interaction in general: Many drug-drug interactions are pharmacokinetic (one drug increases plasma levels of another through metabolic inhibition) or additive pharmacodynamic effects (two drugs with independent mechanisms combine linearly), a taxonomy the EPA (2000) develops formally for chemical mixture risk assessment.
This sourceOffice of Research and Development. Regulatory framework prescribing dose-addition and response-addition baselines for combined exposures and deviations interpreted as synergy or antagonism in mixture toxicology and combined-protocol assessment.

- Synergy and Antagonism
- Mapped back: The formal baseline specification and deviation measurement are translated into operational metrics (failure rate reduction, instrument utilization, personnel hours), paralleling the dose-addition and response-addition baselines the US EPA (2000) prescribes for assessing combined protocols and chemical mixtures.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Was it audited? Yes. A second, independent pass read the citation against the article text and recorded a verdict.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
