1 INTRODUCTION AND SCOPE
This chapter describes the minimum standards to be followed for the preparation of compounded nonsterile preparations (CNSPs) for humans and animals. For purposes of this chapter, nonsterile compounding is defined as combining, admixing, diluting, pooling, reconstituting other than as provided in the manufacturer's labeling, or otherwise altering a drug product or bulk drug substance to create a nonsterile preparation.
The requirements in this chapter must be followed to minimize harm, including death, to human and animal patients that could result from 1) excessive microbial contamination, 2) variability from the intended strength of correct ingredients (e.g., ±10% of the labeled strength), 3) physical and chemical incompatibilities, 4) chemical and physical contaminants, and/or 5) use of ingredients of inappropriate quality.
Handling of nonsterile hazardous drugs (HDs) must additionally comply with Hazardous Drugs-Handling in Healthcare Settings (800)..
1.1 Scope
1.1.1 CNSPs subject to the requirements in this chapter
CNSPs that must comply with this chapter include but are not limited to the following dosage forms:
- Solid oral preparations
- Liquid oral preparations
- Rectal preparations
- Vaginal preparations
- Topical preparations (i.e., creams, gels, and ointments)
- Nasal and sinus preparations intended for local application (i.e., nasal sprays and nasal irrigation)
- Otic preparations (excluding use in perforated eardrums)
1.1.2 - Practices not subject to the requirements in this chapter
The following practices are not considered compounding and are not required to meet the requirements of this chapter. Handling of nonsterile HDs should additionally comply with (800). Refer to facility SOPs for additional safe practices (e.g., labeling).
- Nonsterile radiopharmaceuticals: Compounding of nonsterile radiopharmaceuticals is subject to the requirements in Radiopharmaceuticals-Preparation, Compounding. Dispensing, and Repackaging (825).
- Reconstitution: Reconstitution of a conventionally manufactured nonsterile product in accordance with the directions contained in the manufacturer approved labeling
- Repackaging: Repackaging of conventionally manufactured drug products (see Good Repackaging Practices (1178) for recommendations)
- Splitting tablets: Breaking or cutting a tablet into smaller portions
- Administration: Preparation of a single dose for a single patient when administration will begin within 4 h. This includes crushing a tablet(s) or opening a capsule(s) to mix with food or liquids to facilitate patient dosing.
1.1.3 Personnel and settings affected
This chapter applies to all persons who prepare CNSPs and all places where CNSPs are prepared.
This includes but is not limited to pharmacists, technicians, nurses, physicians, veterinarians, dentists, naturopaths, and chiropractors in all places including but not limited to pharmacies, hospitals and other healthcare institutions, patient treatment sites, and physicians' or veterinarians' practice sites.
The compounding facility's leadership and all personnel involved in preparing, storing, packaging, dispensing, and transporting CNSPs are responsible for 1) ensuring that the applicable practices and quality standards in this chapter are continually and consistently applied to their operations, and 2) proactively identifying and remedying potential problems within their operations. Personnel engaged in the compounding and dispensing of CNSPs must also comply with laws and regulations of the applicable regulatory jurisdiction.
1.1.4 Oversight by designated person(s)
The compounding facility must designate one or more individuals to be responsible and accountable for the performance and operation of the facility and personnel for the preparation of CNSPs. The responsibilities of the designated person(s) include but are not limited to:
- Overseeing a training program to ensure competency of personnel involved in compounding, handling, and preparing CNSPs
- Selecting components
- Monitoring and observing compounding activities and taking immediate corrective action if deficient practices are observed
- Ensuring that standard operating procedures (SOPs) are fully implemented. The designated person(s) must ensure that follow-up is carried out if problems, deviations, or errors are identified
- Establishing, monitoring, and documenting procedures for the handling and storage of CNSPs and/or components of CNSPs
- The designated person(s) must be identified in the facility's SOPs. If the compounding facility has only one person responsible for all compounding in the facility, then that person is the designated person.
2 PERSONNEL TRAINING AND EVALUATION
All personnel who compound or have direct oversight of compounding CNSPs must be initially trained and qualified by demonstrating knowledge and competency according to the requirements in this section (2. Personnel Training and Evaluation) before being allowed to perform their job functions independently.
Designated person(s) are responsible for creating and implementing a training program that describes the required training, the frequency of training, and the process for evaluating the competency of personnel. This program must equip personnel with knowledge and training in the required skills necessary to perform their assigned tasks. Personnel who compound or have direct oversight of compounding personnel must complete training initially and at least every 12 months in appropriate compounding principles and practices as described in this section. Other personnel, who do not compound and only perform functions such as in-process checks, final verification, or dispensing of CNSPs, must undergo training as required by the facility's SOPs.
Training and competency of personnel must be documented as described in 14. Documentation.
Before beginning to compound CNSPs independently or have direct oversight of compounding personnel, personnel must complete training and be able to demonstrate knowledge of principles and competency of skills for performing nonsterile manipulations as applicable to their assigned tasks. Knowledge and competency must be demonstrated initially and at least every 12 months in at least the following core competencies:
- Hand hygiene
- Garbing
- Cleaning and sanitizing
- Handling and transporting components and CNSPS
- Measuring and mixing
- Proper use of equipment and devices selected to compound CNSPS
- Documentation of the compounding process (e.g., 7. Master Formulation and Compounding Records)
Steps in the training procedure must include the following:
- Understand the requirements in this chapter
- Understand and interpret safety data sheets (SDSs) and, if applicable, certificates of analysis (COA)
- Read and understand procedures related to their compounding duties
Training and observation may be performed by the designated person(s) or an assigned trainer. Personnel must be observed and guided throughout the training process. The personnel will then be expected to repeat the procedures independently while under the direct supervision of the designated person(s) and/or assigned trainer. Personnel will be permitted to perform the procedure without direct supervision only after independently demonstrating understanding and competency. Upon completion of the training program, the designated person(s) and/or assigned trainer must document that personnel have been trained and successfully completed competency assessments (see 14. Documentation).
In addition to the initial and annual competency training and evaluation described in this section, the designated person(s) should monitor and observe compounding activities and must take immediate corrective action if deficient practices are observed. Facility SOPs must describe procedures for monitoring and observing compounding activities and personnel.
If the facility has only one person in the compounding operation, that person must document that they have obtained training and demonstrated competency, and they must comply with the other requirements of this chapter.
3 PERSONAL HYGIENE AND GARBING
Individuals entering the compounding area must maintain appropriate personal hygiene. Individuals must evaluate whether they have a personal risk of potentially contaminating the compounding environment and CNSP (e.g., personnel with rashes, recent tattoos, oozing sores, conjunctivitis, or active respiratory infection). Individuals must report these conditions to the designated person(s). Because of the risk of contaminating the CNSP and the environment, the designated person(s) is responsible for evaluating whether these individuals should be excluded from working in compounding areas until their conditions have resolved.
3.1 Personnel Preparation
Personnel engaged in compounding must maintain appropriate hand hygiene and maintain appropriate cleanliness required for the type of compounding performed.
Before entering the compounding area, compounding personnel must remove any items that are not easily cleanable and that might interfere with garbing. At a minimum, personnel must:
- Remove personal outer garments (e.g., bandanas, coats, hats, and jackets)
- Remove all hand, wrist, and other exposed jewelry, including piercings that could interfere with the effectiveness of garbing or hand hygiene (e.g., watches or rings that may tear gloves)
- Remove earbuds or headphones
The designated person(s) may permit accommodations provided that the quality of the environment and CNSP will not be affected. All accommodations should be documented.
3.2 Hand Hygiene
Personnel must perform procedures necessary for appropriate hand hygiene when entering the compounding area to compound as described in Box 1.
The use of alcohol-based hand rub alone is not sufficient.
Box 1. Hand Hygiene Procedures
- Wash hands with soap and water for at least 30 s - Dry hands completely with disposable towels or wipers - Don gloves |
To minimize the risk of cross contaminating other CNSPs and contaminating other objects (e.g., pens and keyboards), gloves should be wiped or replaced before beginning a CNSP that has different components.
All gloves must be inspected for holes, punctures, or tears and must be replaced immediately if such defects are detected.
3.3 Garb and Glove Requirements
Gloves must be worn for all compounding activities. Other garb (e.g., shoe covers, head or hair covers, facial hair covers, face masks, and gowns) must be appropriate for the type of compounding performed and should be worn as needed for the protection of personnel from chemical exposures and for prevention of CNSP contamination. Garbing requirements and frequency of changing garb must be determined by the facility and documented in the facility's SOPs.
Garb must be replaced immediately if it becomes visibly soiled or if its integrity is compromised. All gloves must be inspected for holes, punctures, or tears and must be replaced immediately if such defects are detected. Garb must be stored in a manner that minimizes contamination (e.g., away from sinks to avoid splashing).
Garb should be removed when leaving the compounding area. When personnel exit the compounding area, garb, except for gowns, should be discarded. Disposable garb must not be laundered. If gowns are worn, they may be reused if not damaged or soiled. If gowns are to be reused, they must remain in the compounding area, and should only be reused during the same shift. The facility's SOPs must describe cleaning and sanitization procedures for reusing goggles, respirators, and other reusable equipment.
If compounding an HD, appropriate personal protective equipment (PPE) must be worn and disposed of in accordance with (800)..
4 BUILDINGS AND FACILITIES
4.1 Compounding Area
An area must be designated for nonsterile compounding. The method of designation must be described in the facility's SOPs. Other activities must not be occurring in the compounding area at the same time as compounding. The compounding area must be well lit and must be maintained in a clean, orderly, sanitary condition and in a good state of repair. There should not be carpet in the compounding area.
The compounding area must provide for the orderly placement of equipment and materials to prevent mix-ups among components, containers, labels, in-process materials, and finished CNSPs. The area should be designed, arranged, and used in a way that minimizes cross contamination from noncompounding areas.
4.2 Storage Area
Compounding personnel must monitor temperatures in the storage area(s) either manually at least once daily on days that the facility is open, or continuously with a temperature recording device to ensure the temperature remains within the appropriate range for the CNSPs and components. The results of the temperature readings must be documented on a temperature log or stored in the continuous temperature recording device and must be retrievable. All temperature monitoring equipment must be calibrated or verified for accuracy as recommended by the manufacturer or every 12 months if not specified by the manufacturer.
The compounding facility must adhere to SOPs to detect and reduce the risk of temperature excursions within the storage area(s).
When it is known that a CNSP or component has been exposed to temperatures either below or above the storage temperature limits for the CNSP or component, personnel must determine whether the CNSP or component integrity or quality has been compromised, and, if so, the CNSP or component must be discarded.
All CNSPs, components, equipment, and containers must be stored off the floor in a manner that prevents contamination and permits inspection and cleaning of the storage area(s).
4.3 Water Sources
A source of hot and cold water and an easily accessible sink must be available. The sink must be emptied of all items unrelated to compounding and must be cleaned if visibly soiled before being used to clean any equipment used in nonsterile compounding. The plumbing system must be free of defects that may contribute to the contamination of any CNSP. Purified Water (see Water for Pharmaceutical Purposes (1231), 3.1.1 Purified Water), distilled water, or reverse osmosis water should be used for rinsing equipment and utensils.
5 CLEANING AND SANITIZING
Cleaning and sanitizing the surfaces in the nonsterile compounding area(s) must occur on a regular basis at the minimum frequencies specified in Table 1 or, if compounding is not performed daily, cleaning and sanitizing must be completed before initiating compounding. Cleaning and sanitizing must be repeated when spills occur and when surfaces are visibly soiled. Applicable cleaning and sanitizing must be documented daily on days when compounding occurs.
Surfaces should be resistant to damage by cleaning and sanitizing agents. Floors in the compounding area should be easily cleanable and should not be porous or particle generating.
Cleaning and sanitizing agents must be selected and used with consideration of compatibilities, effectiveness, and minimal potential to leave residues.
If cleaning and sanitizing are performed as separate steps, cleaning must be performed first.
Table 1. Minimum Frequency for Cleaning and Sanitizing in Nonsterile Compounding Area(s)-Surfaces
| Site | Minimum Frequency |
| Work surfaces | - At the beginning and end of each shift on days when compounding occurs, after spills, and when surface contamination (e.g., from splashes) is known or suspected - Between compounding CNSPs with different components |
| Floors | - Daily on days when compounding occurs, after spills, and when surface contamination (e.g., from splashes) is known or suspected |
| Walls | - When visibly soiled, after spills, and when surface contamination (e.g., from splashes) is known or suspected |
| Ceilings | - When visibly soiled and when surface contamination (e.g., from splashes) is known or suspected |
| Storage shelving | - Every 3 months, after spills, and when surface contamination (e.g., from splashes) is known or suspected |
6 EQUIPMENT AND COMPONENTS
6.1 Equipment
The equipment and components used for compounding a CNSP must be suitable for the specific compounding process.
Equipment surfaces that contact components must not be reactive, additive, or sorptive, and must not alter the quality of the CNSP. Disposable or dedicated equipment may be used to reduce the chance of bioburden and cross contamination.
Equipment must be stored in a manner that minimizes the risk of contamination and must be located to facilitate equipment use, maintenance, and cleaning. Equipment and devices used in the compounding or testing of compounded preparations must be inspected prior to use and, if appropriate, verified for accuracy as recommended by the manufacturer at the frequency recommended by the manufacturer or at least every 12 months, whichever is more frequent. After compounding, the equipment must be cleaned to prevent cross contamination of the next preparation.
Weighing, measuring, or otherwise manipulating components that could generate airborne chemical particles (e.g., active pharmaceutical ingredients [APIs), added substances, and conventionally manufactured products) must be evaluated to determine if these activities must be performed in a closed-system processing device to reduce the potential exposure to personnel or contamination of the facility or CNSPs. Examples of closed-system processing devices include containment ventilated enclosures (CVEs), biological safety cabinets (BSCs), and single-use containment glove bags. The process evaluation must be carried out in accordance with the facility's SOPs, and the assessment must be documented.
If a CVE or BSC is used, it must be certified at least every 12 months according to manufacturer specifications or other laws and regulations of the applicable regulatory jurisdiction.
If a BSC, CVE, or other nondisposable device is used, it must be cleaned as described in Table 2.
Table 2. Minimum Frequency for Cleaning and Sanitizing in Nonsterile Compounding Area(s)-Equipment
| Site | Minimum Frequency |
| CVE | - At the beginning and end of each shift on days when compounding occurs, after spills, and when surface contamination (e.g., from splashes) is known or suspected - Clean and sanitize the horizontal work surface of the CVE between compounding CNSPs with different components |
| BSC | - At the beginning and end of each shift on days when compounding occurs, after spills, and when surface contamination (e.g., from splashes) is known or suspected - Clean and sanitize the horizontal work surface of the BSC between compounding CNSPs with different components - Clean and sanitize under the work surface at least monthly |
| Other devices and equipment used in compounding operations | - Before rst use and thereafter in accordance with the manufacturer’s recommendations - If no recommendation is available, between compounding CNSPs with different components |
6.2 Components
The compounding facility must have written SOPs for the selection and inventory control of all components from receipt to use in a CNSP.
SDSs must be readily accessible to all personnel working with components located in the compounding facility. Personnel must be instructed on how to retrieve and interpret needed information.
6.2.1 Component selection
Designated person(s) must be responsible for selecting components to be used in compounding.
APIs:
- Must comply with the criteria in the USP-NF monograph, if one exists
- Must have a COA that includes specifications (e.g., compendial requirements for quality) and test results for the component that show the API meets expected quality
- In the United States, must be manufactured by an FDA-registered facility
- Outside of the United States, must comply with the laws and regulations of the applicable regulatory jurisdiction
All components other than APIs:
- Should be accompanied by a COA that verifies that the component meets the criteria in the USP-NF monograph, if one exists, and any additional specifications for the component
- In the United States, should be manufactured by an FDA-registered facility (If a component cannot be obtained from an FDA-registered facility, the designated person(s) must select a component that is suitable for the intended use.)
- Outside of the United States, must comply with the laws and regulations of the applicable regulatory jurisdiction
Water:
- Purified Water or better quality, e.g., Sterile Water for Irrigation, must be used for compounding nonsterile drug preparations when formulations indicate the inclusion of water
6.2.2 Component receipt
Upon receipt of components other than conventionally manufactured products, the COA must be reviewed to ensure that the component has met the acceptance criteria in an appropriate USP-NF monograph, if one exists. The following information must be documented (see 14. Documentation) according to the facility's SOPs: receipt date, quantity received, supplier name, lot number, expiration date, and results of any in-house or third-party testing performed.
For all components that lack a vendor expiration date, the date of receipt by the compounding facility must be clearly and indelibly marked on each packaging system. Packaging systems of components (i.e., API and added substances) that lack a vendor's expiration date must not be used by the compounding facility after 3 years from the date of receipt. A shorter expiration date must be assigned according to Pharmaceutical Compounding-Sterile Preparations (797), 9.3.2 Component receipt if the same component container is also used in sterile compounding or if the ingredient is known to be susceptible to degradation.
Any component found to be of unacceptable quality must be promptly rejected, clearly labeled as rejected, and segregated from active stock to prevent use before appropriate disposal. Any other lots of that component from the same vendor must be examined to determine whether the other lots have the same defect.
6.2.3 Component evaluation before use
Before use, compounding personnel must visually re-inspect all components. Each packaging system must be inspected to detect any container breakage, looseness of the cap or closure, or deviation from the expected appearance or texture of the contents that might have occurred during storage.
Compounding personnel must ascertain before use that components are of the correct identity based on the labeling and have been stored under required conditions in the facility.
If the identity, strength, purity, and quality of components intended for preparation of CNSPs cannot be verified (e.g., containers with damaged or incomplete labeling), the components must be immediately rejected. Any component found to be of unacceptable quality must be promptly rejected, clearly labeled as rejected, and segregated from active stock to prevent use before appropriate disposal.
6.2.4 Component handling
All components must be handled in accordance with the manufacturer's instructions or per laws and regulations of the applicable regulatory jurisdiction. The handling must minimize the risk of contamination, mix-ups, and deterioration (e.g., loss of identity, strength, purity, or quality). For each use, the lot must be examined for evidence of deterioration and other aspects of unacceptable quality. Once removed from the original container, any component not used in compounding (e.g., excess after weighing) should be discarded and not returned to the original container to minimize the risk of contaminating the original container.
6.2.5 Component spill and disposal
The facility must maintain current chemical hazard and disposal information (e.g., SDSs). Such information must be made accessible to compounding personnel.
The management and documentation of nonhazardous component spills and disposal must be described in the facility's SOPs.
The facility must have a readily accessible spill kit in the compounding area.
All personnel who may be required to remediate a spill must receive training in spill management of chemicals used and stored at the compounding facility. Training must be conducted at least every 12 months and documented for all personnel who may be required to clean up a spill.
Waste of any component must be disposed of in accordance with laws and regulations of the applicable regulatory jurisdiction. For information on the handling of HDs, see (800).
7 MASTER FORMULATION AND COMPOUNDING RECORDS
7.1 Creating Master Formulation Records
A master formulation record (MFR) is a detailed record of procedures that describes how the CNSP is to be prepared. An MFR must be created for each unique formulation of a CNSP. CNSPs are prepared according to the MFR, and the details of each preparation are documented on a compounding record (see 7.2 Creating Compounding Records). Any changes or alterations to the MFR must be approved and documented according to the facility's SOP. See Box 2 for information that must be included in an MFR.
Box 2. Master Formulation Record
An MFR must include at least the following information: - Name, strength or activity, and dosage form of the CNSP - Identities and amounts of all components; if applicable, relevant characteristics of components (e.g., particle size, salt form, purity grade, solubility) - Container closure system(s) - Complete instructions for preparing the CNSP including equipment, supplies, and description of compounding steps. - Physical description of the final CNSP - Beyond-use date (BUD) and storage requirements. - Reference source to support the assigned BUD - If applicable, calculations to determine and verify quantities and/or concentrations of components and strength or activity of the API(s) - Labeling requirements (e.g., shake well) - Quality control (QC) procedures (e.g., pH testing, visual inspection) and expected results - Other information needed to describe the compounding process and ensure repeatability (e.g., adjusting pH, temperature) |
7.2 Creating Compounding Records
A compounding record (CR) documents the compounding of each CNSP. A CR must be created for all CNSPs. Each CR must be reviewed for completeness before the CNSP is released. The name or other unique identifier of the person completing the review and the date of the review must be documented on the CR. The CR must permit traceability of all components in the case of a recall or known quality issue. The MFR can be used as the basis for preparing the CR. For example, a duplicate can be made of the MFR with blank fields for recording the information necessary to complete the CR. See Box 3 for information that must be included in a CR.
Box 3. Compounding Record
A CR must include at least the following information: - Name, strength or activity, and dosage form of the CNSP - Date-or date and time-of preparation of the CNSP - Assigned internal identification number (e.g., prescription, order, or lot number) - A method to identify the individuals involved in the compounding process and individuals verifying the final CNSP - Name, vendor or manufacturer, lot number, and expiration date of each component - Weight or measurement of each component - Total quantity of the CNSP compounded - Assigned beyond-use date (BUD) and storage requirements - If applicable, calculations to determine and verify quantities and/or concentrations of components and strength or activity of the API(s) - Physical description of the nal CNSP - Results of quality control procedures (e.g., pH testing and visual inspection) - MFR reference for the CNSP |
8 RELEASE INSPECTIONS AND TESTING
All release inspections must be included in the facility's documentation (see Z. Master Formulation and Compounding Records and 11. SOPs). All checks, inspections, and any other required tests to ensure the quality of the CNSP must be detailed in the facility's MFR.
8.1 Visual Inspection
At the completion of compounding, before releasing and dispensing, the CNSP must be visually inspected to determine whether the physical appearance of the CNSP is as expected (e.g., color, texture, physical uniformity). Some CNSPs, as noted in their MFR, also must be visually checked for certain characteristics (e.g., emulsions must be checked for phase separation). The CNSP must be visually inspected to confirm that the CNSP and its labeling match the CR and the prescription or medication order. The inspection also must include a visual inspection of container closure integrity (e.g., checking for leakage, cracks in the container, or improper seals).
When a CNSP will not be released or dispensed on the day of preparation, a visual inspection must be conducted immediately before it is released or dispensed to make sure that the CNSP does not exhibit any defects (e.g., leakage) that could develop during storage. Any CNSP found to be of unacceptable quality (e.g., observed defects) must be promptly rejected, clearly labeled as rejected, and segregated from active stock to prevent use before appropriate disposal.
9 LABELING
Every CNSP must be labeled with appropriate, legible identifying information to prevent errors during storage, dispensing, and use. The term labeling designates all labels and other written, printed, or graphic matter on the immediate container or on or inside any packaging system or wrapper in which the article is enclosed, except any outer shipping container. The term label designates the part of the labeling on the immediate container. (See Labeling (7).)
All labeling must be in compliance with laws and regulations of the applicable regulatory jurisdiction.
The label on each container of the prepared CNSP must, at a minimum, display prominently and legibly the following information:
- Assigned internal identification number (e.g., barcode, prescription, order, or lot number)
- Active ingredient(s), and their amount(s), activity(ies), or concentration(s)
- Storage conditions if other than controlled room temperature
- BUD
- Dosage form
- Total amount or volume if it is not obvious from the container
The labeling on the dispensed CNSP should display the following information:
- Route of administration
- Indication that the preparation is compounded
- Any applicable special handling instructions
- Any applicable warning statements
- Compounding facility name, and contact information if the CNSP is to be sent outside of the facility or healthcare system in which it was compounded
Labeling procedures must be followed as described in the facility's SOPs to prevent labeling errors and CNSP mix-ups.
The label of the CNSP must be verified to ensure that it conforms with the following:
- Prescription or medication order;
- MFR (see 7.1 Creating Master Formulation Records); and
- CR (see 7.2 Creating Compounding Records).
10 ESTABLISHING BEYOND-USE DATES
10.1 Terminology
Each CNSP label must state the date, or the hour and date, beyond which the preparation cannot be used and must be discarded (i.e., the BUD). BUDs for CNSPs are calculated in terms of hours, days, or months.
BUDs and expiration dates are not the same. An expiration date identifies the time during which a conventionally manufactured product, API, or added substance can be expected to meet the requirements of a compendial monograph, if one exists, or maintain expected quality, provided it is kept under the prescribed storage conditions. The expiration date limits the time during which a conventionally manufactured product, API, or added substance may be dispensed or used (see (7), Labels and Labeling for Products in Other Categories, Expiration Date and Beyond-Use Date).
10.2 Parameters to Consider in Establishing a BUD
BUDs for CNSPs should be established conservatively to ensure that the preparation maintains its required characteristics to minimize the risk of contamination or degradation.
When establishing a BUD for a CNSP, compounders must consider parameters that may affect quality, including but not limited to the following:
- Chemical and physical stability properties of the API and any added substances in the preparation (e.g., if the API and added substances in the preparation are known to rapidly degrade over time and/or under certain storage conditions, reduce the strength of the preparation, or produce harmful impurities)
- Compatibility of the container closure system with the finished preparation (e.g., leachables, interactions, adsorption, and storage conditions)
- Degradation of the container closure system, which can lead to a reduction in integrity of the CNSP
- Potential for microbial proliferation in the CNSP
- Significant deviations from essential compounding steps and procedures; changes to essential compounding steps may have an impact on the stability of the formulation
10.3 Establishing a BUD for a CNSP
The BUDs in Table 4 are based on the ability of the CNSP to maintain chemical and physical stability and to suppress microbial growth. These BUDs represent the limit for CNSPs that are packaged in tight, light-resistant containers unless conditions in 10.4 CNSPs Requiring. Shorter BUDs or 10.5 Extending BUDs for CNSPs apply.
The aqueous and nonaqueous dosage forms in Table 4 are defined based on the water activity (aW) of the most similar drug preparations described in Table 3 or Application of Water Activity Determination to Nonsterile Pharmaceutical Products (1112). In general, the use of aW aids in assessing the susceptibility of CNSPs to microbial contamination and the potential for API degradation due to hydrolysis. The aW is different from the water content and may be considered as the available water to support microbial growth and hydrolytic reactions. Nonaqueous dosage forms will not support spore germination or microbial growth due to their low aW. Reduced aW greatly assists in the prevention of microbial proliferation in conventionally manufactured products and is expected to convey the same benefit to CNSPs.
Compounders are not required to measure aW for CNSPs. While the manufactured products in (1112), Table 2 and compounded preparations in Table 3 below are not exhaustive, they provide examples of dosage forms that have an aW < 0.6 and those that have an aW ≥ 0.6 and can assist personnel in determining the BUD by dosage form using Table 4.
When preparing CNSPs, raw materials and equipment contribute a bioburden to the final preparation. CNSPs with an aW ≥ 0.6, and a BUD within the limits of Table 4, should contain suitable antimicrobial agents to protect against the proliferation of bacteria, yeast, and mold contamination that may be inadvertently introduced anytime during the compounding process or throughout the BUD under appropriate handling and storage conditions. All CNSPs with an extended BUD must follow 10.5 Extending BUDs for CNSPs. Careful consideration should be taken when selecting a preservative to ensure microbiological effectiveness and stability. When antimicrobial preservatives are contraindicated in a CNSP, storage of the preparation in a refrigerator is required if such storage does not change the physical or chemical properties of the CNSP (i.e., precipitation).

Table 4. BUD Limit by Type of Preparation in the Absence of a USP−NF Compounded Preparation Monograph or CNSP-Specic Stability Informationa
| Type of Preparation | BUD (days) | Storage Temperatureb |
| Aqueous Dosage Forms (aW ≥ 0.60) | ||
| Nonpreserved aqueous dosage formsc | 14 | Refrigerator |
| Preserved aqueous dosage formsc | 35 | Controlled room temperature or refrigerator |
| Nonaqueous Dosage Forms (aW < 0.60) | ||
| Oral liquids (nonaqueous)d | 90 | Controlled room temperature or refrigerator |
| Other nonaqueous dosage formse | 180 | Controlled room temperature or refrigerator |
a A shorter BUD must be assigned when the physical and chemical stability of the CNSP is less than the BUD limit stated in the table (see 10.4 CNSPs Requiring Shorter BUDs).
b See Packaging and Storage Requirements (659).
c An aqueous preparation is one that has an aW ≥ 0.6 (e.g., emulsions, gels, creams, solutions, sprays, or suspensions).
d A nonaqueous oral liquid is one that has an aW < 0.6.
e Other nonaqueous dosage forms that have an aW < 0.6 (e.g., capsules, tablets, granules, powders, nonaqueous topicals, suppositories, and troches or lozenges).
10.4 CNSPs Requiring Shorter BUDs
The BUDs in Table 4 are the BUD limits for CNSPs in the absence of specific stability information. This does not absolve the designated person(s) from performing due diligence to determine if there is existing stability data that would require a shorter BUD.
Additionally,
- The BUD of the CNSP must not exceed the shortest remaining expiration date of any of the commercially available starting components.
- For CNSPs prepared from one or more compounded components, the BUD should generally not exceed the shortest BUD of any of the individual compounded components. However, there may be acceptable instances when the BUD of the final CNSP exceeds the BUD assigned to compounded components (e.g., pH-altering solutions). If the assigned BUD of the final CNSP exceeds the BUD of the compounded components, the physical, chemical, and microbiological quality of the final CNSP must not be negatively impacted.
10.5 Extending BUDs for CNSPS
- CNSPs with a USP-NF monograph: When compounding from a USP-NF compounded preparation monograph for the CNSP, the BUD must not exceed the BUD specified in the monograph.
- CNSPs with stability information: If there is a stability study using a stability-indicating analytical method for the API(s), CNSP formulation, and material of composition of the container closure that will be used, then the BUD indicated by the study may be used in lieu of the BUDs specified in Table 4 for aqueous and nonaqueous dosage forms, up to a maximum of 180 days.
If the BUD of the CNSP is extended beyond the BUDs in Table 4, an aqueous CNSP must be tested for antimicrobial effectiveness (see Antimicrobial Effectiveness Testing.(51)). The designated person(s) may rely on antimicrobial effectiveness testing that is conducted (or contracted for) once for each formulation in the particular container closure system-including materials of composition of the container closure system-in which it will be packaged. Alternatively, the designated person(s) may rely on antimicrobial effectiveness testing results provided by an FDA-registered facility or published in peer-reviewed literature as long as the CNSP formulation (including any preservative) and container closure materials of composition are the same as those tested (unless a bracketing study is performed). When a bracketing study is performed, antimicrobial effectiveness testing may be performed on a low concentration and on a high concentration of the active ingredient in the formulation to establish preservative effectiveness across various strengths of the same formulation (e.g., bracketing). The concentration of all other ingredients (including preservatives) must fall within the bracketed range.
11 SOPS
Facilities preparing CNSPs must develop SOPs on all aspects of the compounding operation. All personnel who conduct or oversee compounding activities must be trained in the facility's SOPs and be responsible for ensuring that they are followed.
One or more person(s) must be designated to ensure that the facility's SOPs are fully implemented. The designated person(s) must ensure that follow-up occurs if problems, deviations, or errors are identified.
12 QUALITY ASSURANCE AND QUALITY CONTROL
Quality assurance (QA) is a system of procedures, activities, and oversight that ensures that the compounding process consistently meets quality standards. Quality control (QC) is the sampling, testing, and documentation of results that, taken together, ensure that specifications have been met before release of the CNSP. See Quality Assurance in Pharmaceutical Compounding (1163).
A facility's QA and QC programs must be formally established and documented in the facility's SOPs that ensure that all aspects of the preparation of CNSPs are conducted in accordance with the requirements in this chapter ((795)) and the laws and regulations of the applicable regulatory jurisdiction. Designated person(s) must ensure that the facility has formal, written QA and QC programs that establish a system of
- Adherence to procedures,
- Prevention and detection of errors and other quality problems,
- Evaluation of complaints and adverse events, and
- Appropriate investigations and corrective actions.
The facility's SOPs must describe the roles, duties, and training of the personnel responsible for each aspect of the QA program.
Designated person(s) responsible for the QA program must have the training, experience, responsibility, and authority to perform these duties. The overall QA and QC program must be reviewed at least once every 12 months by the designated person(s). The results of the review must be documented, and appropriate action must be taken if needed.
12.1 Notification About and Recall of Dispensed CNSPs
The facility must have procedures in place to
- Determine when recalls must be initiated, which should include procedures to immediately notify the prescriber of a failure of specifications with the potential to cause patient harm (e.g., strength, purity, or other quality attributes)
- Recall any unused dispensed CNSPs and quarantine any stock remaining in the pharmacy
- Investigate if other lots are affected and recall if necessary
An SOP for recall of dispensed CNSPs must contain
- Procedures to determine the severity of the problem and the urgency for implementation and completion of the recall
- Procedures to determine the distribution of any affected CNSP, including the data and quantity of distribution
- Procedures to identify patients who have received the CNSP
- Procedures for disposal and documentation of the recalled CNSP
- Procedures to investigate and document the reason for recall
The nonsterile compounding facility must document the implementation of the recall procedures. The recall must be reported to appropriate regulatory bodies as required by the laws and regulations of the applicable regulatory jurisdiction.
12.2 Complaint Handling
Compounding facilities must develop and implement SOPs for handling complaints. Complaints may include but are not limited to concerns or reports on the quality, labeling, or possible adverse reactions related to a specific CNSP.
A designated person(s) must review all complaints to determine whether the complaint indicates a potential quality problem with the CNSP. If it does, a thorough investigation into the cause of the problem must be initiated and completed. The investigation must consider whether the quality problem extends to other CNSPs. Corrective action, if necessary, must be implemented for all potentially affected CNSPs.
Consider whether to initiate a recall of potentially affected CNSPs and whether to cease nonsterile compounding processes until all underlying problems have been identified and corrected.
A readily retrievable written or electronic record of each complaint must be kept by the facility, regardless of the source of the complaint (e.g., email, telephone, or mail). The record must contain the name of the complainant or other unique identifier, the date the complaint was received, the nature of the complaint, and the response to the complaint. In addition, to the extent that the information is known, the following should be recorded: the name and strength of the CNSP and the assigned internal identification number (e.g., prescription, order, or lot number).
The record must also include the findings of any investigation and any follow-up. Records of complaints must be easily retrievable for review and evaluation for possible trends and must be retained in accordance with the record-keeping requirements in 14. Documentation. A CNSP that is returned in connection with a complaint must be quarantined until it is destroyed after completion of the investigation and in accordance with laws and regulations of the applicable regulatory jurisdiction.
12.3 Adverse Event Reporting
Adverse events potentially associated with the quality of CNSPs must be reported in accordance with the facility's SOPs and all laws and regulations of the applicable regulatory jurisdiction. If the investigation into an adverse event reveals a quality problem with a CNSP that is likely to affect other patients, those patients and prescribers potentially affected must be informed.
13 CNSP PACKAGING AND TRANSPORTING
13.1 Packaging of CNSPs
The facility's SOPs must describe packaging of CNSPs. Personnel should select and use packaging materials that will maintain the physical and chemical integrity and stability of the CNSPs. Packaging materials must protect CNSPs from damage, leakage, contamination, and degradation, while simultaneously protecting personnel from exposure.
13.2 Transporting of CNSPs
If transporting CNSPs, the facility must have written SOPs to describe the mode of transportation, any special handling instructions, and whether temperature monitoring devices are needed.
14 DOCUMENTATION
All facilities where CNSPs are prepared must have and maintain written or electronic documentation to demonstrate compliance with the requirements in this chapter. This documentation must include, but is not limited to, the following:
- Personnel training, competency assessments, and qualification records including corrective actions for any failures
- Equipment records (e.g., calibration, verification, and maintenance reports)
- COAs and all documentation required for components not conventionally manufactured
- Receipt of components
- SOPs, MFRs, and CRs
- Release inspection and testing records
- Information related to complaints and adverse events including corrective actions taken
- Results of investigations and corrective actions
- Records of cleaning and sanitizing the designated compounding area
- Temperature logs
- Accommodations to personnel compounding CNSPs
- Any required routine review (e.g., yearly review of QA and QC programs, yearly review of chemical hazard and disposal information)
Documentation must comply with all laws and regulations of the applicable regulatory jurisdiction. Records must be legible and stored in a manner that prevents their deterioration and/or loss. All required CRs for a particular CNSP (e.g., MFR, CR, and release inspection and testing results) must be readily retrievable for at least 2 years after preparation or as required by the laws and regulations of the applicable regulatory jurisdiction, whichever is longer.
