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.
