Lecture #1 - Intro Flashcards
What are is non-sterile compounding?
Mixing 2 manufactured products
Diluting a liquid
Adding a flavor
Preparation of an ointment, solution, etc.
What is sterile compounding?
IV admixtures
What is the purpose for compounding?
Provide individualized patient care
Unavailable dose or dosage form (ie. adjust strength)
Allergies to manufactured product (ie. reformulation)
Child or pet friendly (ie. unable to swallow)
Flavoring for palatability
Combination to make a final product
Is adding flavoring to a conventionally manufactured product considered compounding?
Yes, flavoring may destabilize the product and affect BUD
What is the BUD if flavoring is added to a manufactured product that DOES NOT contain a preservative?
14 days refrigerated
What is the BUD if flavoring is added to a manufactured product that CONTAINS a preservative?
35 days under controlled room temp or refrigerated
How many categories of compounding are there?
7 categories → 2 non-sterile, 3 sterile, 2 other misc
What are the different categories of NON-STERILE compounding?
Category 1 - simple: mixing commercial products
Category 2 - complex: bulk drug or calc required (ie. using concentrated stock soln)
What are the different categories of STERILE compounding?
Category 3 - Risk Level 1 = LOW (simple: 2-3 ingredients)
Category 4 - Risk Level 2 = MEDIUM (> 3 ingredients mixed)
Category 5 - Risk Level 3 = HIGH (complex: 1 or more non-sterile equipment or ingredient)
What are the other different categories of compounding?
Category 6 - Radiopharmaceuticals
Category 7 - Veterinary
What is the difference between USP and NF?
NF = National Formulary : contains excipient monographs
USP = U.S. Pharmacopeia : contains monographs for drugs, preparations, ingredients, and supplements
What are General Chapters in USP-NF?
Description of tests and procedures referred to in monographs
What are General Notices in USP-NF?
Provides definitions for terms used in monographs and info necessary to understand the monograph
What are the differences between USP <795>, <797>, and <800>?
<795> is for non-sterile preparations
<797> is for general sterile preparations
<800> is for hazardous drugs and chemotherapy
What are the USP <795> standards for compounding NON-STERILE medications? Why is it needed?
Reduce risks of contamination, infection, or incorrect dosing
-Accepted variability of +/- 10% of labeled strength
-Nasal sprays/irrigations are non-sterile preparations
-Gloves must be worn
-Clean before sanitizing (use lab-grade detergents designed to not leave residues)
What are some legal restrictions on compounding?
Necessary compounding
Product can be compounded PRIOR to receiving Rx, BUT in limited quantities and based on history of receiving Rx
Only for individual patient
What is the difference between compounding and manufacturing?
Compounding = creation of drug product that is not commercially available to meet unique needs of a patient
Manufacturing = producing a drug by extraction of substances
What facilities are considered for the compounding environment?
Space (ie. air, light, temp, humidity)
Separate space for sterile preparation
Measures to prevent cross contamination
Water
What are the different types of water used in compounding environment?
Portable Water = hand/equipment washing
Purified Water = non-sterile
Water for Injection / Bacteriostatic water (contains preservatives) = sterile
What factors need to be considered for compounding equipment?
Comply with USP standards (ie. design, size)
Material doesn’t absorb or react w/ ingredients
Equipment is inspected, cleaned, and maintained
What are the major NON-STERILE compounding equipment?
Mortar and pestle
Spatulas
Beakers
Graduated cylinder
Conical graduated cylinder
What is the purpose of using a beaker vs. graduated cylinder vs. conical graduate?
Beaker = mixing things together
Graduated cylinder = measuring volumes of NON-VISCOUS liquids
Conical graduate = measuring VISCOUS liquids and allows mixing of 2-faced systems
What is the minimum volume measurable for a graduated cylinder?
20% of the graduated cylinder volume
What are the types of stability?
Chemical, physical, microbiological, therapeutic, toxicological
