21 CFR Part 11

The FDA regulation setting requirements for electronic records and electronic signatures to be trustworthy and equivalent to paper — audit trails, access controls and validated systems.

A

Action limit

A preset monitoring threshold that, when exceeded, obliges a defined, documented response — not merely a review.

ALCOA+

The data-integrity principles regulators expect records to meet: Attributable, Legible, Contemporaneous, Original and Accurate — plus Complete, Consistent, Enduring and Available.

Alert limit

A preset monitoring threshold that, when exceeded, signals a drift from normal and triggers review before control is lost.

Annex 1

The EU GMP annex governing manufacture of sterile medicinal products. The 2022 revision put the contamination control strategy at its centre and raised the bar on demonstrated, not just documented, control.

Aseptic processing

Manufacturing that maintains sterility by excluding contamination at every step, used when a product cannot be terminally sterilised in its final container.

B

Batch record

The complete documented history of a production batch, showing that it was made and controlled according to the approved process.

Bioburden

The population of viable microorganisms present on a raw material, component or product prior to sterilisation.

Biologic

A medicinal product manufactured in or derived from living systems — such as vaccines, monoclonal antibodies and cell or gene therapies.

C

CAPA

Corrective & Preventive Action

The systematic process of investigating a problem, correcting it, and preventing recurrence — a backbone of any quality management system.

Cleanroom grades

Grade A–D

The EU GMP cleanliness classes for controlled environments. Grade A is the critical zone where sterile product is exposed; Grade B is its background; C and D are for less critical stages.

Computer Software Assurance

CSA

A risk-based FDA approach to validating computerised systems that favours critical thinking and targeted testing over exhaustive documentation.

Contamination Control Strategy

CCS

A documented, site-wide set of controls for microbial, particulate and pyrogen contamination, with a rationale linking each identified risk to a control and its monitoring.

Continuous manufacturing

Producing drug product in an uninterrupted flow rather than discrete batches, enabling tighter control, smaller footprints and faster release.

Contract manufacturer

CDMO

A Contract Development and Manufacturing Organisation that develops and/or produces product on behalf of another company.

D

Data integrity

The assurance that data is complete, consistent and accurate throughout its lifecycle — the foundation of trustworthy GMP records and regulatory decisions.

Deviation

A departure from an approved instruction, procedure or specification, requiring documented investigation and disposition.

E

Environmental monitoring

EM

Routine sampling of cleanroom air, surfaces and personnel for microbial and particulate contamination, used to demonstrate a controlled state over time.

Excursion

A monitoring result that breaches an alert or action limit, requiring investigation and, at the action limit, a defined response.

Extractables & leachables

E&L

Chemicals that can migrate from contact materials (such as single-use assemblies) into product — assessed to confirm patient safety.

F

Form 483

The form an FDA investigator issues at the close of an inspection, listing observed conditions that may violate GMP requirements.

G

Good Manufacturing Practice

GMP

The system of regulations, procedures and controls ensuring that medicinal products are consistently produced and controlled to quality standards appropriate to their use.

I

Isolator

A sealed, decontaminated enclosure that provides a controlled Grade A environment for aseptic work, fully separating the operator from the process.

L

LIMS

Laboratory Information Management System

Software that manages samples, tests, results and associated data across a laboratory, supporting traceability and data integrity.

Lyophilisation

Freeze-drying

Removing water from a frozen product under vacuum to yield a stable dry cake — common for biologics and reconstitutable injectables.

M

Media fill

A process simulation that runs sterile growth media through the line in place of product, used to validate that aseptic processing keeps the product sterile.

MES

Manufacturing Execution System

Software that manages and records production on the shop floor in real time, enforcing the process and replacing paper batch records.

N

Nitrosamine

A class of probable carcinogenic impurities that can form in some drug substances and products, prompting risk assessments and control limits.

P

Process validation

Documented evidence that a process, operated within set parameters, consistently produces product meeting its predetermined quality attributes.

Q

Quality by Design

QbD

A systematic development approach that builds quality into a product by understanding and controlling the process, rather than testing quality in at the end.

R

Rapid microbial methods

RMM

Technologies that return microbial results faster than traditional plate counts, shortening the loop between detection and action and enabling quicker release.

Restricted-Access Barrier System

RABS

A physical and aerodynamic barrier that limits operator contact with the critical (Grade A) zone during aseptic processing.

S

Single-use systems

SUS

Disposable, pre-sterilised components — bags, tubing and assemblies — used once and discarded, reducing cleaning and cross-contamination risk.

Sterility assurance

The overall confidence — built from design, process control and monitoring — that a product is sterile, rather than sterility inferred from an end-product test alone.
