The amount or concentration associated with a defined response in a specified comparison, distinct from the maximum achievable effect.
- Efficacy
The capacity to produce a specified effect under the relevant conditions, distinguished from potency and individual clinical suitability.
- Selectivity
The relative preference for a biological target, which can depend on exposure and does not imply absolute specificity.
- Clearance
The proportional removal of drug relative to its measured concentration, expressed as a volume per unit time under the relevant model.
- Apparent distribution volume
A model quantity relating the amount of drug in the body to concentration, rather than a literal anatomical fluid container.
- Bioavailability
The relevant fraction of an administered dose reaching systemic circulation under the stated route, product and comparison assumptions.
- Disintegration
The breakup of a dosage form into smaller components, which is distinct from dissolving the active ingredient and absorbing it.
- Dissolution
Movement of a substance into solution under specified conditions, influenced by the actual material, environment and dosage-form design.
- Modified release
A delivery design altering release characteristics, whose safe manipulation depends on the actual formulation and current product instructions.
- Precision
Agreement among repeated measurements under defined conditions, which does not alone establish agreement with an appropriate true or reference value.
- Selectivity of an assay
The ability to assess the intended target in the presence of relevant other components under the validated method conditions.
- Stability evidence
Data supporting the behavior of a particular product over time under specified conditions, rather than one universal expiry convention.
- Preanalytical error
A problem arising before measurement through identification, collection, handling or storage, which can change the reported laboratory result.
- Screening result
An initial classification under a defined testing purpose, interpreted with performance and population context rather than automatic final diagnosis.
- Decision limit
A threshold used for a defined clinical decision under a particular framework, which need not equal a population reference-interval boundary.
- Medication review
A structured assessment of the actual medicine list, indications, benefit, risk and practical use in the context of the patient.
- Teach-back
A communication method checking the explanation through the person account of understanding, used to improve clarity rather than assign blame.
- Therapeutic objective
The intended patient-relevant benefit used to assess whether a medicine plan is useful, with monitoring for harms and limitations.
- Medication reconciliation
Comparison and investigation of medicine information across care transitions to distinguish intended changes from unintended discrepancies.
- Near miss
A detected medication-process problem that did not result in the feared harm but can still reveal a useful system weakness.
- High-alert medicine
A medicine associated with important harm potential when used incorrectly, requiring controls matched to the actual risk and process.
- Absolute risk reduction
The comparator risk minus the intervention risk for a defined outcome and follow-up, interpreted with uncertainty and actual applicability.
- Allocation concealment
Protection against knowledge of the next randomized assignment during recruitment, distinct from blinding later assessment or treatment.
- Cost perspective
The specified viewpoint defining which resources and outcomes enter an economic comparison, rather than acquisition price alone.
- Qualification scope
The actual organizer, level, professional role and assessment purpose of a credential, distinguished from a similar title in another jurisdiction.
- Traceability
Records connecting a product, preparation or treatment with its relevant identity and history so appropriate investigation and action remain possible.
- Professional authorization
The actual permission for a defined service under current local requirements, which is not conferred by a scientific practice question.
