(1) Except as otherwise provided by law or the board’s rules,
the United States Pharmacopeia–NF (2023), General Chapter 797
Pharmaceutical Compounding – Sterile Preparations (www.
usp.org), is incorporated by reference (hereafter “USP Chapter
797”) and available at 12601 Twinbrook Parkway, Rockville,
MD 20852. This rule does not incorporate any subsequent
amendments or additions to USP Chapter 797. In the event
of a conflict between USP Chapter 797 and Missouri law or
board rules, Missouri law and board rules shall control. Except
as otherwise provided by law or rule, licensees shall comply
with all provisions of USP Chapter 797 and the additional
requirements of this rule.
(A) The use of technologies, techniques, materials, or
procedures other than those described in USP Chapter 797
are prohibited, unless the technology, technique, material,
or procedure is validated in accordance with applicable
provisions of USP Chapter 1223 and USP Chapter 1225 and is
approved by the board in advance after submission of scientific
data evidencing the specific technology, technique, material,
or procedure is safe, effective, and meets or exceeds USP
Chapter 797 requirements.
(B) The permit holder and pharmacist-in-charge (PIC) are
responsible for ensuring compliance with state and federal
law and USP Chapter 797, including ensuring compliance
for activities delegated to a designated person, as defined by
Chapter 797. Identification of a designated person as defined
by USP Chapter 797 shall not exempt or modify any duty or
responsibility of the permit holder or PIC under the board’s
rules or state and federal law.
(C) For purposes of this rule, compounding shall be defined
as provided in USP Chapter 797, provided that compounded
sterile preparations (CSPs) also includes—
1. Docking of proprietary bag and vial systems; and
2. Mixing, reconstituting, or preparing an FDA-approved
manufactured sterile product in accordance with the manufac
turer’s approved labeling recommendations.
(D) The pharmacy must have current reference material(s)
related to CSPs available, as applicable to the pharmacy’s com
pounding activities.
(E) Except as otherwise provided herein, sterile compounding
must also comply with 20 CSR 2220-2.400.
(F) USP Chapter 797, Section 21, and the exemption in USP
Chapter 797, Section 1.1.2, governing allergen extracts are not
incorporated in this rule and shall not be applicable.
(G) USP Chapter 797, Section 1.3, and the exemption in USP
Chapter 797, Section 1.3, governing immediate use CSPs is not
incorporated in this rule and shall not be applicable. Preparation
of a vaccine for immediate administration pursuant to 20 CSR
2220-6.050 is not considered sterile compounding.
(H) The board recommends but does not require compliance
with USP Chapter 800. In the interim, pharmacies that
compound sterile hazardous drugs, as defined by lists
maintained by National Institute for Occupational Safety
and Health (NIOSH), are required to establish policies and
procedures that include all aspects of handling hazardous
drugs, including but not limited to personal protective
equipment, use and maintenance of appropriate primary
engineering controls, transport, storage, labeling, disposal,
spill control, compounding procedures, personnel training,
and deactivating, decontaminating, cleaning, and disinfecting.
(I) Class E radiopharmaceutical pharmacies must comply
with USP Chapter 825, 20 CSR 2220-2.500, and all applicable
rules of the board for radiopharmaceutical activities.
(J) Unless otherwise provided by law or court of competent
jurisdiction, the provisions of this rule are only applicable to
pharmacy services under the jurisdiction of the board and
are not applicable to hospital pharmacy services under the
jurisdiction of the Missouri Department of Health and Senior
Services pursuant to Chapter 197, RSMo.
(2) Personnel Education, Training, and Evaluation. Licensees
shall comply with all USP Chapter 797 personnel education,
training, and evaluation requirements.
(A) Individuals who fail an aseptic manipulation competency
evaluation or a garbing and hand hygiene competency
evaluation must undergo requalification through additional
training by competent compounding personnel. The pharmacy
must investigate such failure and take appropriate corrective
actions prior to the individual resuming compounding.
Corrective actions must be documented in the pharmacy’s
records.
(B) Required competency evaluation results can be trans
ferred between facilities under common ownership or control
of the same pharmacy or healthcare facility, provided the
competency evaluation captured the most difficult and chal
lenging conditions the individual will be performing and was
completed within USP Chapter 797’s required time frames.
Pharmacies accepting transferred competency evaluation re
sults under this section must maintain current and written
policies and procedures governing the transfer of results.
Licensees or registrants with transferred competency evalu
ation results must be trained on applicable pharmacy opera
tional procedures as needed to ensure proper compounding
and must be skilled and trained to accurately and competently
perform the duties assigned.
(C) If needed to prevent interruptions in patient care during
an emergency, a pharmacy may also accept the required
competency evaluations from another pharmacy or hospital in
lieu of the required initial competency evaluations, provided—
1. A pharmacist verifies the applicable competency evalu
ation complies with USP Chapter 797;
2. The pharmacy maintains documentation of the other
pharmacy’s or hospital’s completed competency evaluation(s),
including the dates and results. Additionally, the receiving
pharmacy must maintain a manual or electronic copy of
the other pharmacy’s or hospital’s policies and procedures
on aseptic manipulation competency evaluations for board
licensees or registrants;
3. The board licensee or registrant has received training
on applicable pharmacy operational procedures as needed to
ensure proper compounding. The licensee or registrant must
be skilled and trained to accurately and competently perform
the duties; and
4. Individuals may not assist with compounding under the
emergency allowance authorized by this subsection for more
than forty-five (45) days without the required competency
evaluation by the pharmacy that complies with USP Chapter
797.
(3) Facilities and Equipment. The pharmacy shall establish and
follow proper controls to ensure environmental quality, prevent
environmental contamination, and maintain air quality in all
International Organization for Standardization (ISO) classified
areas, in addition to compliance with USP Chapter 797.
(A) To minimize impact on patient care, Class H sterile com
pounding pharmacies licensed on the effective date of this rule
may petition the board for a waiver of USP Chapter 797 facility
and equipment requirements if immediate compliance with
USP Chapter 797 requirements cannot be completed despite
the permit holder’s due diligence or would result in an undue
hardship or adversely impact patient care. Waivers may be
effective for a time period designated by the board, provided
all Class H sterile compounding pharmacies must comply with
USP Chapter 797 facility and equipment requirements within
two (2) years of the effective date of this rule.
(B) Certification of primary engineering controls (PECs)/ISO
classified areas must be conducted by competent staff/vendors
in accordance with USP Chapter 797 using recognized and
appropriate certification and testing equipment. Certification
results must be reviewed by a designated person as defined by
USP Chapter 797. The individual’s identity and date of review
must be documented in the pharmacy’s records. Deficiencies
or failures that may impact preparation sterility or quality must
be investigated and corrected prior to further compounding,
which may include recertification of the PEC/ISO classified area.
(C) PECs, cleanroom suites, and segregated compounding
areas (SCA) must be designed and maintained to minimize mi
crobial contamination and maintain air quality. Cleaning and
disinfecting supplies must be low-lint, including tool handles
and holders. Additionally, dust-collecting overhangs, such as
utility pipes, and ledges, such as windowsills, must be mini
mized. The pharmacy’s policies and procedures must address
selecting, handling, and monitoring of cleaning, disinfecting,
and sporicidal agents to prevent/minimize equipment damage
and decay and to ensure environmental quality and prepara
tion integrity. The pharmacy must also have policies/proce
dures for inspecting the PECs, cleanroom suite, SCA, and equip
ment and correcting/repairing any damage, rust, or corrosion.
(D) For SCAs, the area within one (1) meter of the PEC must be
dedicated only for sterile compounding (e.g., not storage, hand
hygiene, donning and doffing garb, or other highly particlegenerating activities such as patient care).
(4) Garbing and Hand Hygiene. The following requirements
apply in addition to USP Chapter 797:
(A) For restricted-access barrier systems (RABS) as defined
by USP Chapter 797, the RABS and the pharmaceutical isolator
sleeves and gloves must be changed per the manufacturer’s
recommendations and as defined in the pharmacy’s policies/
procedures; and
(B) Disposable gloves must be worn inside the gloves at
tached to the RABS sleeves. Sterile gloves must be worn over
the gloves attached to the RABS sleeve.
(5) Record Keeping.
(A) In addition to USP Chapter 797 requirements, the following
must be documented/maintained for all sterile compounding:
1. Manufacturer manuals relied on to properly operate
equipment;
2. Other facility quality control logs, as appropriate,
including all maintenance, cleaning, and calibration records;
3. Sterilization records, if applicable;
4. Quarantine records, if applicable;
5. End-preparation evaluation and testing records; and
6. Ingredient validation records, if applicable (e.g.,
Certificate of Analysis).
(B) All records, policies/procedures and reports required by
USP Chapter 797 or this rule must be maintained electronically
or as a hard-copy for two (2) years and must be readily
retrievable and subject to inspection by the board of pharmacy
or its agents. At a minimum, records shall be physically or
electronically produced immediately or within two (2) hours of
a request from the board.
(C) In lieu of a compounding log as required by 20 CSR 22202.400, Class H pharmacies must maintain a compounding
record for each preparation that complies with USP Chapter
797. The compounding record must include a prescription
number or other readily retrievable unique identifier assigned
for which the compound was dispensed.
(6) End-Preparation Evaluation.
(A) In addition to USP Chapter 797 requirements, the phar
macy must have a procedure for a pre-release check of the
potency of the active ingredients in a CSP prepared from
non-sterile active ingredients. The procedure shall include at
least the following verifications by a pharmacist:
1. The lot of the active ingredients used for compounding
have the necessary labeling, potency, purity, certificate of anal
ysis, and other relevant qualities;
2. All weighings, calculations, volumetric measurements,
and additions of ingredients were carried out properly; and
3. The compounding or control records include documen
tation that the fill volumes of all units available for release
were checked and were correct.
(B) A CSP may be released for emergency dispensing pending
test results, if approved by the prescriber. A separate autho
rization from the prescriber is required for each emergency
dispensing. For purposes of this rule, emergency dispensing is
defined as a situation where a preparation is necessary for im
mediate administration and no alternative product or prepara
tion is available. Documentation of the emergency dispensing,
the prescriber’s approval, and the need for the emergency
must appear within the prescription record.
(7) Microbiological Air and Surface Monitoring. The pharmacy
shall establish and follow proper controls to ensure environ
mental quality, prevent environmental contamination, and
maintain air quality in all ISO classified areas. Applicable envi
ronmental monitoring of air and surfaces must be conducted
as required by USP Chapter 797. In addition to USP Chapter
797 requirements, microbiological air and surface monitoring/
testing results must be promptly reviewed by a designated
person as defined by USP Chapter 797. The reviewer’s identity
and date of review must be documented in the pharmacy’s
records. When conducted, routine surface sampling must be
performed under dynamic conditions, but before the area has
AND INSURANCE
been cleaned and disinfected.
(8) Remedial Investigations. A remedial investigation is required
if any environmental monitoring sample demonstrates a
colony forming unit (CFU) count that exceeds USP Chapter
797 recommended action levels for the type of sampling. The
remedial investigation must be documented and include
resampling of all affected areas to ensure a suitable state
of microbial control. The pharmacy must ensure that no
misbranded, contaminated, or adulterated CSP is administered
or dispensed for patient use.
(A) If an environmental monitoring sample taken from a
PEC exceeds USP Chapter 797 action levels, the pharmacy
must cease compounding in the affected PEC until resampling
shows a suitable state of microbial control has been achieved
in the PEC. However, a pharmacy may continue to compound
during the remedial investigation if—
1. The affected PEC is cleaned and disinfected by using
an Environmental Protection Agency (EPA) registered sterile
cleaning, disinfecting, and sporicidal agent, or a combination
thereof, followed by sterile isopropyl alcohol;
2. The beyond-use date assigned to all preparations is no
greater than twelve (12) hours; and
3. The affected PEC is resampled under dynamic conditions.
If the resampling exceeds USP Chapter 797 action levels,
compounding must cease until resampling shows a suitable
state of microbial control has been achieved in the PEC, unless
otherwise authorized by the board or board’s authorized
designee to continue compounding upon showing the facility
can be operated in a manner not to endanger the public health
or safety.
(B) If an environmental monitoring sample taken from a
buffer room exceeds USP Chapter 797 action levels, the phar
macy must cease compounding in the affected buffer room
until resampling shows a suitable state of microbial control has
been achieved in the buffer room. However, a pharmacy may
continue to compound during the remedial investigation if—
1. The affected buffer room is cleaned and disinfected by
using an EPA registered cleaning, disinfection, and sporicidal
agents, or a combination thereof;
2. The beyond-use date assigned to all preparations is no
greater than twenty-four (24) hours; and
3. The affected buffer room is resampled under dynamic
conditions. If two (2) consecutive resamplings exceed USP
Chapter 797 action levels, compounding must cease until res
ampling shows a suitable state of microbial control has been
achieved in the affected room, unless otherwise authorized
by the board or board’s authorized designee to continue com
pounding upon a showing that the facility can be operated in
a manner not to endanger the public health or safety.
(C) Pharmacies must notify the board in writing within three
(3) business days if a resample is collected as part of a remedial
investigation that exceeds USP Chapter 797 action levels.
(9) Recalls. A recall must be initiated when a dispensed CSP
is deemed to be misbranded, adulterated, or non-sterile or if
end-preparation testing results are out of specification. The
pharmacy shall notify the prescriber of the nature of the recall,
the problem(s) identified, and any recommended actions to
ensure public health and safety. In cases where the CSP has the
potential to harm the patient, the same notification must be
provided to all patients that received the recalled CSP(s). Any
recall initiated by a pharmacy shall be reported, in writing, to
the board within three (3) business days. The pharmacy shall
document their activities related to the recall.
