Quality assurance (QA)
A program of activities used to ensure that the procedures used in preps of compounds lead to products that meet certain specifications and standards
26
Typical components of a good QA program include
SOPs, formulation records, compounding worksheets, ingredient record forms, material safety data sheets, documented training, and QA tests for each compound
27
Standard operating procedures (SOPs) are
A step by step written instructions on how to do a certain task. All important tasks should be covered by a SOP
28
SOPs should be developed for
Facility maintenance, equipment calibration and maintenance, personnel training and validation, and preparation, packaging, and storing of compounded items.
29
SOPs can assure that
Equipment is properly maintained and calibrated, supplies and chemicals are received, inventoried, compliant with compounding standards, stored properly and disposed of correctly, all procedure and tasks are performed consistently and documented
30
SOP general format follow
1. SOP number - unique assigned number 2. Date effective 3. Author 4. Author signature 5. Purposes of procedure 6. Equipment/ materials listed for each task 7. Detailed procedure 8. Documentation forms
31
PCAB accreditation requires SOPs to regard
Cleaning, maintenance, calibration and verification of each piece of equipment
32
Capsules:
Oral dosage, been used for more than a century. Offers broad range of dosage options for patients.
33
Tablets:
Solid dosage form administered orally, sublingually, vagina lily or as an implant under the skin. Compressed tables made by manufacturers are most commonly prescribed dosage form.
34
Sublingually means
Under the tongue, preparations may be administered by placing them under the tongue and allowing them to dissolve.
35
Powder is a
Solid dosage form made from blended active ingredients and excipients.
36
Lozenge is a
Solid dosage form administered orally to be dissolved in the mouth
37
Trachea is a
Interchangeable term for lozenge but sometimes prepared in soft form
38
Suppository is a
Solid dosage form used to administer medication by way of the rectum, vagina, or urethral tract
39
Aqueous solutions are
Water soluble
40
Powders are a solid dosage that may be used
Either internally (BC powder) or externally (talcum powder). Use of powders has declined, but still an occasional need.
41
Some advantages of using torches and lozenges are that they
Easily to handle and administer to a variety of patients, base is made of sugar torches generally have a pleasant taste which makes them popular with pediatric, geriatric, and hospice patients.
42
Sticks :
Unique dosage form used for topical application of local anesthetic, sunscreens, antivirals, antibiotics, and cosmetics. Convenient, relatively stable and fairly easy to repair but time consuming.
43
A suppository dissolves
At body temperatures, allowing absorption of medication into surrounding tissues. Can have a systemic effect or local effect depending on desired effect expected by prescriber or on the drug being used.
44
Common bases for suppositories
Battibase, poly base, cocoa butter
45
Drug in a suppository can either be
Dissolved or suspended
46
Solutions:
Water soluble chemical dissolved in the water phase of compounding. May contain just enough water to dissolve the drug or may be as much as 50% of the final volume.
47
Suspensions:
Preparation that contains insoluble solid particles uniformly dispersed though-out a vehicle. Must be shaken prior to administration.
48
Suspensions need a suspending agent such as
Ora plus or Karo syrup
49
Emulsions:
Liquid or semisolid preparation that can be taken orally or applied topically.
50
Emulsions are prepaired when
Two immiscible liquids must be dispensed in the same preparation
51
Emulsions are held together by a
Emulsifying agent
52
Emulsions are either
Water-in-oil or oil-in-water Internally oil-in-water Topical could be both
53
Ointments:
Semisolid, usually applied to skin or mucosal tissue. Doe not penetrate into the skin, should be soft and easily spreadable and smooth in texture.
54
Common ointment bases are
Hydrophilic petrolatum, aquaphor, hydrous ianolin, and PEG ointments.
55
Comminuting or triturating
Process of reducing particle size to a fine powder
56
Pastes:
Stiff or very viscous, do not melt or soften at body temp. Intended as protective covering over areas where applies. (Diaper rash)
57
Cream:
Soft, opaque solid applied externally. Dissipate into skin healing the affected area from inner layers of dermis. Medications are usually dissolved or suspended in water soluble base.
58
Some cream bases available include
Vanishing cream, HRT base, cetaphil, Eucerin, lubriderm
59
Gels:
Semisolid system consisting of suspensions made up of small inorganic particles or large organic molecules interpenetrated by a liquid.
60
Transdermal gel
Unique, semisolid dose that becoming increasingly popular. Have special absorption enhancers that “push” medication though the layers of skin so it can be absorbed into the blood stream.
61
Most common form of transdermal gel is a
Two phase vehicle made from plutonic lecithin organogel (PLO) consists of both oil phase and an aqueous phase. Making it suitable for many chemicals/
62
Poloxamer gel is a
Liquid stored in the fridge. When brought to room temp it will form a gel. Final product should be stored at room temp.
63
Ophthalmic preps:
For the eye. May be a solution, suspension, or ointment. Must be sterile.
64
Ophthalmic solutions must be
Clear and particulate free, and is the most commonly prepared in compounding
65
The eye generally tolerates a pH rang of
4 to 11
66
Buffers are used to
Maintain the pH of a product
67
Preservatives are necessary when
Prep is intended for multiple uses. They prevent contamination of preparation from microbial growth.
68
Optic preps:
For the ear, (otic) made in liquid, powder or ointment form.
69
Vehicles most often used for otic liquids are
Propylene glycol, glycerin, polyethylene glycol, vegetable oil, mineral oil. Necessary to use viscous liquid because medication should adhere to the ear canal.

The vehicle, buffers, preservatives, tonicity adjusting agents.
72

Sodium chloride 0.9% and sterile water for injection
73
Veterinary compounding:
One of the fastest growing areas of compounding. Doses are usually calculated on milligrams per kilogram of body weight. Making for a more accurate dose.
74
Successfully _____ medication is a critical step in the process, especially when a drug is bitter.
Flavoring
75
A psychological impact for medication is
Flavor and color
76
Individuals are usually more sensitive to the
Aroma of a prep then the actual taste. Older patients may require added amounts of flavor. Females tend to be more sensitive to smell then males.
77
Pediatric flavoring
Children have more taste buds, meaning more sensitive to taste. Infants and children tend to prefer sweet tases and do not respond well to bitter flavors. Flavors could include raspberry, bubblegum, marshmallow, butterscotch, citrus, berry and vanilla. The younger the patient the more mild the flavor should be.
78
Adult flavoring
