CERTAIN PHARMACEUTICAL PRODUCTS MUST BESTERILE

TWO CATEGORIES OF STERILE PRODUCTS

those that can be sterilized infinal container (terminally

sterilized)

those that cannot be terminallysterilized and must beaseptically prepared

Aseptic processing

• Objective is to maintain the sterility of aproduct, assembled from sterile components

• Operating conditions so as to prevent microbialcontamination

COMPOUNDED STERILE PREPARATIONS (CSPS)USP 797 (REVISED 2015 USP 39 PAGE 626

• Scope : to all persons who prepare CSPs (e.g., pharmacists,pharmacy technicians, physicians, veterinarians, and nurses)at all places where CSPs are prepared (e.g., hospitals andother healthcare institutions, patient treatment sites, infusionfacilities, pharmacies, and physicians’ or veterinarians’practice sites).

MAJOR EDITS TO THE CHAPTER INCLUDE

1. Collapsed compounded sterile preparations (CSP) microbial risk categories fromthree to two and changed terminology. No sterile compounding is inherently “lowrisk” .

- Category 1 CSPs have a shorter beyond use date (BUD) and may be prepared ina segregated compounding area;

- Category 2 CSPs have a longer BUD and must be prepared in a cleanroomenvironment.

2. Removed specific information on handling of hazardous drugs and addedreferences to Hazardous Drugs—Handling in Healthcare Settings 800ۧۦ .

3. Introduced terminology for “in-use time” : CSP must be used after it has beenopened or punctured.

COMPOUNDED STERILE PREPARATIONS (CSPS)USP 797 (REVISED 2015)

1) microbial contamination (nonsterility),

2) excessive bacterial endotoxins,

3) variability from the intended strength of correct ingredients,

4) chemical and physical contaminants,

5) use of ingredients of inappropriate quality.

ContaminationContamination

Contamination rate increasing during filling

This could indicate acontamination originated in theliquid media path (i.e. wrongaseptic connection to the mediatank, contamination in therecirculation loop).

It is important to keep underaseptic conditions the mediabulk tank at the end of filling,while waiting the media fillresults, for verifying thishypothesis

RISK FACTOR

Batch size

Complexity of the compounding process

(e.g., number of manipulations involved; whether starting with nonsterileor sterile components)

Inherent nature of the drug being compounded

(e.g., whether the drug is susceptible to microbial growth; whether thepreparation will be preservative free)

Complexity of the compounding operation

(e.g., multiple people in the cleanroom at the same time; multiple CSPsbeing prepared at the same time; activity in the surrounding areas)

Length of time between the start of compounding

(including making a stock solution) and administration of the drug to thepatient

DANGER

Antineoplastic agents are typically used as cancerchemotherapeutic agents.

Antineoplastic hazardous agents are genotoxic,teratogenic, carcinogenic, or toxic to other targetorgans even at very low concentrations

7 GROUP OF ANTINEOPLASTIC

Alkylating agents:

Alkylating agents undergo alkylation by a nucleophilic substitution reaction with cellularconstituents, such as DNA base pairs, cell membranes, proteins, and proteins.

Antitumor antibiotics:

The antitumor antibiotics are synthesized from microorganisms. The antitumorantibiotics either break-up DNA strands, slow, or stop DNA synthesis.

Antimetabolites:

Antimetabolites are structurally similar to metabolites required for normal biochemicalreactions. Antimetabolites interfere with cellular processes such as cell division.

7 GROUP OF ANTINEOPLASTIC

Nitrosoureas:

Nitrosoureas act similar to that of alkylating agents and slow down or stop enzymes that helprepair DNA.

Mitotic agents (plant alkaloids):

Plant alkaloids break DNA strands and prevent cell replication.

Hormonal agents:

Steroids lyse lymphoblasts and thus directly cause lymphoid malignancies.

Miscellaneous agents:

Though mechanisms of miscellaneous agents are not well understood, these agents probablyinhibit DNA, RNA, and protein synthesis.

ORAL CYTOTOXIC

· All layers : of the packaging must be clearly marked ascytotoxic including the outer bag that contains thesupply

· The container should offer protection from the lightwhere required.

- Where cytotoxic medication is supplied in glass

bottles then a pharmacist must confirm whetherother containers are suitable for dispensing orwhether it is essential that the glass bottle be used toavoid any adverse affects on the drug

6/1/2016

· If a blister pack is used,- this must be filled by the pharmacist dispensing the

chemotherapy and- labeled with relevant instructions with a cytotoxic warning

label.- Other non cytotoxic medication MUST NOT be placed into the

same pack

· Oral chemotherapy agents should be stored:- as directed by the pharmacist,- in a secure manner,- out of the reach of children

· Tablet containers should have child proof caps. Where this isnot the case, care should be taken to ensure that they arekept out of the reach of children
