Numerical limits, ranges, or other suitable measures for acceptance of test results. (TR 14) (TR 29) (TR 38) (TR 64) Numerical limits, ranges, or other suitable measures for acceptance of test results. Exceeding the acceptable range for a critical parameter during subsequent validation studies may result in questionable product quality that would require initiation of an investigation. Exceeding the operating range should be documented and explained in the validation report and evaluated for validation study impact. (TR 42) The pre-defined specifications, standards or ranges that must be met under stated test conditions. (TR 48) Numerical limits, ranges, or other suitable measures for acceptance of the results of analytical method validation that is satisfied to determine suitability of test method performance.(TR 57) (TR 69) (TR 72) (TR 74) The criteria that a system or component must satisfy in order to be accepted by a user or other authorized entity. (TR 54-5) Numerical limits, ranges, or other suitable measures for acceptance of the results of analytical procedures which the drug substance or drug product or materials at other stages of their manufacture should meet (16). Exceeding the acceptable range for a critical parameter during subsequent validation studies may result in questionable product quality that would require initiation of an investigation and possible batch rejection. (TR60)

An internal (in-house) value used to assess the consistency of the process. The cause of the excursion should be investigated and documented and corrective action is generally required. Action limits are not specifications. (TR42) An established internal (in-house) data-based value which is part of the control strategy and used to assess the consistency of the manufacturing process. An action limit excursion result in an investigation, identification of recovered isolates, root-cause analysis, assessment of a systemic failure and impact on product quality and patient safety. (TR69) An established internal (in-house) data-based value that is part of the control strategy and used to assess the consistency of the manufacturing process. An action limit excursion result in an investigation, identification of recovered isolates, root-cause analysis, assessment of a systemic failure and impact on product quality and patient safety. (TR74) A limit that, when exceeded, indicates a process is outside of its normal operating range. A response to such an excursion should involve a documented investigation and corrective actions based on the results of that investigation. (TR60)

Synonym: Drug Substance. (TR14) (TR42) A substance or mixture of substances that, when delivered in a finished drug product, directly affects the structure or function of the body. (TR54-4) Any substance or mixture of substance intended to be used in the manufacture of a drug (medicinal) product and that, when used in the production of a drug, becomes an active ingredient of the drug product. Such substances are intended to furnish pharmacological activity or other direct effect in the diagnosis, cure, mitigation, treatment, or prevention of disease or to affect the structure and function of the body. Note: also known as Drug Substance. (TR29) (TR56) (TR41) (TR54-3) (TR60) Any substance or mixture of substances intended to be used in the compounding of a drug preparation, thereby becoming the active ingredient in that preparation and furnishing pharmacological activity o other direct effect in the diagnosis, cure, mitigation, treatment, or prevention of disease in humans and animals or affecting the structure and function of the body. (TR63) (TR70) Any substance or mixture of substances intended to be used in the manufacture of a drug product, and that when used in the production of a drug, becomes an active ingredient in the drug product. Such substances are intended to furnish pharmacological activity or other direct effect in the diagnosis, cure, mitigation, treatment or prevention of disease, or to affect the structure and function of the body. (TR74)

Documentation and description of work done during the early phases of development. The goal is to document information about the way the process works and to document why key choices were made in selecting the specifics of the process (e.g., flow rate or temperature). These documents can serve as a reference during investigations of discrepancies and during the design of specific Validation and characterization studies.(TR14) (TR 42) Documentation and description of work done during the early phases of development (Stage 1). The goal is to document information about the way the process works and to document why key choices were made in selecting the specifics of the process (e.g., flow rate or temperature). These documents can serve as a reference during investigations of deviations and during the design of specific validation and process characterization studies.(TR60)

A pharmaceutical product type that contains a drug substance, generally, in association with excipients. [Synonym: Dosage Form; Finished Product] (TR57)(TR14)(TR42) A finished dosage form (e.g., tablet, capsule, or solution) that contains a drug substance, generally, but not necessarily, in association with one or more other ingredients.(TR38) (TR67) (TR88) The dosage form in the final immediate packaging intended for marketing.(TR60)(TR82)

Documented verification that the equipment or systems, as installed or modified, comply with the approved design, the manufacturer’s recommendations, and/or user requirements. (TR14) (TR42) (TR48) (TR61) (TR64) The documented verification that the facilities, systems and equipment, as installed or modified, comply with the approved design and the manu­facturer’s recommendations. (TR54-5) Documented verification that the equipment or systems, as installed or modified, comply with the approved design, the manufacturer’s recommendations, and/or user requirements (17). (TR60)

A document that defines the process validation scope and rationale and that contains the list of process validation studies to be performed (Synonym: Validation Master Plan). (TR42) (TR60) The plan that documents rationale for the approach to validation and lists all systems and their validation status. (Note: The VMP can be used to document the rationale for number of monitors and revalidation frequency, as well as other system justifications). (TR52)
