USP <795> Pharmaceutical Compounding Nonsterile Preparations

USP <795> provides standards for healthcare professionals who compound nonsterile preparations. These guidelines were established to ensure patient safety and product quality in the compounding process. The chapter outlines requirements for facilities, equipment, personnel, documentation, and quality assurance.

Introduction to USP <795>

The United States Pharmacopeia (USP) Chapter <795> sets forth the minimum standards for compounding nonsterile pharmaceutical preparations. This chapter is recognized by the Food and Drug Administration (FDA) and provides a framework for pharmacies to follow when they compound medications. The standards were developed to address concerns about patient safety and medication quality while recognizing the essential role that compounding plays in healthcare.

Scope of the Chapter

USP <795> applies to all healthcare settings that compound nonsterile preparations, including:

• Community pharmacies
• Hospital pharmacies
• Long-term care facilities
• Clinics and physician offices
• Home infusion services
• Other healthcare facilities that engage in compounding

The chapter does not apply to sterile compounding, which is covered under USP <797>, nor to compounding that occurs in manufacturing facilities regulated under current good manufacturing practice (cGMP) requirements.

Requirements for Compounding Nonsterile Preparations

USP <795> establishes specific requirements for the compounding of nonsterile preparations:

• Appropriate facilities and equipment must be used
• Personnel must be properly trained and qualified
• Quality assurance processes must be in place
• Documentation must be complete and accurate
• Beyond-use dating must be appropriate
• Storage and handling requirements must be followed

Facilities and Equipment

The standard outlines requirements for compounding areas, including:

• Designated compounding areas that are separate from standard dispensing areas
• Adequate lighting, ventilation, and temperature control
• Appropriate equipment for compounding activities
• Procedures for cleaning and maintenance of facilities and equipment
• Measures to prevent contamination and cross-contamination

Compounding areas should be maintained in a clean, organized manner free from clutter and potential sources of contamination. Equipment calibration and preventive maintenance programs should be established.

Personnel Training and Qualifications

USP <795> requires that personnel involved in compounding activities receive appropriate training and demonstrate competency in:

• Compounding procedures and techniques
• Proper handling of ingredients
• Documentation requirements
• Quality assurance processes
• Safety considerations

Training should be documented and updated periodically to ensure continued competency. Supervisors of compounding activities must have adequate knowledge and experience to oversee operations effectively.

Quality Assurance and Control

Quality assurance programs described in USP <795> include:

• Establishing policies and procedures for compounding
• Monitoring and evaluating compounding practices
• Conducting audits and performance reviews
• Implementing corrective actions when errors or deviations occur
• Continuous improvement processes

These programs help ensure the safety, identity, strength, quality, and purity of compounded preparations.

Documentation and Record-Keeping

USP <795> emphasizes the importance of thorough documentation, including:

• Compounding formulas and procedures
• Ingredients and their sources
• Batch records
• Quality control measures
• Beyond-use dating calculations
• Disposal records

Records must be maintained according to state and federal requirements and be readily available for inspection.

Beyond-Use Dating Considerations

USP <795> provides guidance on determining appropriate beyond-use dates (BUD) for compounded preparations, considering factors such as:

• Stability of the formulation
• Nature of the ingredients (water-based vs. non-water-based)
• Storage conditions
• Container and closure system
• Intended use of the preparation

The chapter provides specific guidelines for BUD based on preparation type:

Preparation Type	Storage Conditions	Maximum Beyond-Use Date
Water-containing oral/dermal preparations	Cold (refrigeration)	14 days
Water-containing oral/dermal preparations	Room temperature	30 days
Non-water-containing solid oral dosage forms	Room temperature	6 months
Non-water-containing liquid topical/oral preparations	Room temperature	6 months

Updates and Recent Changes

The most recent revision of USP <795> (effective November 1, 2023) introduced significant changes including:

• Enhanced requirements for compounding personnel training
• Updated terminology and definitions
• Revised stability testing requirements
• Strengthened quality assurance provisions
• Clarified guidance on BUD for specific preparation types
• New requirements for environmental monitoring

Practitioners should be familiar with these updates and implement any necessary changes to their compounding practices.

Common Compliance Challenges

Healthcare facilities often face challenges in implementing USP <795> requirements, including:

• Adequate space for designated compounding areas in limited facilities
• Maintaining comprehensive training programs with staff turnover
• Implementing robust documentation systems
• Conducting regular quality assurance activities
• Keeping up with updates and changes to requirements
• Managing resources for environmental monitoring

Pharmacist Responsibilities

Pharmacists play a critical role in implementing and maintaining compliance with USP <795>. Their responsibilities include:

• Ensuring that compounded preparations are suitable for their intended use
• Establishing and maintaining compounding procedures
• Training and supervising compounding personnel
• Documenting all compounding activities
• Monitoring and evaluating facility compliance
• Implementing quality improvement processes

Risk Assessment in Compounding

USP <795> emphasizes the importance of risk assessment in compounding activities. This involves:

• Evaluating the complexity of preparation categories
• Identifying potential contamination sources
• Determining appropriate compounding environments
• Establishing quality assurance measures based on risk level

Complex formulations are subject to more stringent requirements to ensure safety and quality.

Sourcing and Verifying Components

USP <795> includes guidance on the selection and use of components in compounding:

• Components should be appropriate for their intended use
• Source materials should be from reliable suppliers
• Certificates of analysis should be obtained when appropriate
• Components should be inspected upon receipt
• Storage conditions should maintain component integrity

Conclusion

USP <795> provides an essential framework for ensuring the safety and quality of compounded nonsterile preparations. Adherence to these standards protects patients and supports the important role that compounding plays in personalized healthcare. Pharmacists and healthcare professionals must maintain up-to-date knowledge of these requirements and implement effective practices to achieve compliance and ensure optimal patient outcomes.
