Glossary Terms (Simple List)

Active Unit Load Device (Active ULD)
A Unit Load Device (ULD) container used to consolidate cargo on aircraft that contains electrical or battery-powered temperature control systems for transporting temperature-sensitive materials; an RKN type is used in an FMEA example. (TR58)
A unit load device with an active heating and/or cooling system that is typically used in air transportation, usually operated from externally supplied AC or DC power or from internal batteries. (TR64)

Activity
Ability of endotoxin (LPS) to initiate the LAL cascade in the compendial bacterial endotoxins test (BET) assay, or the ability to elicit a pyrogenic response in a compendial pyrogen test (2,10). Activity can be measured by other assays such as the monocyte activation test (MAT) or recombinant Factor C tests (rFc), if such tests have been validated, to demonstrate that decisions made from the results are comparable to or superior to the compendial assay. Activity is measured in endotoxin units (EU). In terms of activity, one EU = one IU, regardless of the source. Activity is generally expressed as a concentration, usually EU/mL.(TR82)
-
Adsorption
Retention of solutes, suspended colloidal particles or microorganisms to fluid contact surfaces, e.g., the surfaces of pores in the filter medium. (May be modified with the following terms: electrokinetic, charge-rated, surface charge, hydrophobic or ionic strength. (TR45)
The retention of solutes, suspended colloidal particles or microorganisms to fluid contact surfaces, e.g., the surfaces of pores in filtration membranes. (TR26)
-
Advanced Aseptic Process
A process in which direct intervention with open product containers or exposed product contact surfaces by operators wearing conventional cleanroom garments is not required and never permitted. (TR77)
-
Adventitious Agents
A foreign material that is introduced inadvertently; not natural or hereditary (as in microbial, chemical, or biochemical contamination of a purified substance). (TR 69)
-
Adventitious Virus
An exogenously introduced infectious virus that is unintentionally present in a biological product or its manufacturing process. (TR71) (TR83)
-
Adverse Drug Reaction (ADR)
The American Society of Hospital Pharmacists (ASHP) defines a significant ADR as any unexpected, unintended, undesired, or excessive response to a drug that:
(1) Requires discontinuing the drug (therapeutic or diagnostic) Requires changing the drug therapy
(2) Requires modifying the dose (except for minor dosage adjustment)
(3) Necessitates admission to a hospital
(4) Prolongs stay in a healthcare facility
(5) Necessitates supportive treatment
(6) Significantly complicates diagnosis
(7) Negatively affects prognosis
(8) Results in temporary or permanent harm, disability, or death.
The World Health Organization (WHO) defines ADR as any noxious, unintended, and undesired effect of a drug which occurs at doses used for prophylaxis, diagnosis, or therapy, excluding therapeutic failures, intentional and accidental overdose and drug abuse. It does not consider errors in drug administration to be adverse events. (TR55) -
Adverse Event (AE) Report
An AE report is a communication to the U.S. FDA of an undesirable sign or symptom associated with use of a drug as required and detailed by 21 CFR 314.80. These reports are logged into the U.S. FDA’s Adverse Event Reporting System (AERS). Drug manufacturers are required to report adverse event information to FDA. These reports may also may be voluntarily submitted to the FDA directly by healthcare professionals or the general public at Med Watch. The reports are reviewed, safety issues are monitored, and data are periodically analyzed and assessed by the Center for Drug Evaluation and Research (CDER). (TR55)
-
Adverse Trend
A series of alert-level or action-level excursions that indicates the system or areas are not in control and have the potential to affect the product quality. (TR 70)
An increase in the frequency of alert- and action-level excursions or repeated recovery of low levels of microorganisms below the alert level during microbial monitoring or of pharmaceutical ingredient or finished product failure that is indicative of a loss of process control. (TR88)
