1
New cards

What route are sterile products usually administered?

Parenteral route (injectable)

2
New cards

What is the different between a bactericide and a bacteriostatic?

Bactericide is an agent that kills bacteria while bacteriostatic is an agent that prevents the growth of a bacteria

3
New cards

What is the difference between disinfection and sterilization?

Both kill microorganisms but sterilization kills the spore forms as well, disinfection does not

4
New cards

What is USP 797?

It provides definitions/descriptions/requirements for sterilization compounding

  • It sets the rules of what compounding is and is not

5
New cards

What is USP 800?

Rules/regulations regarding hazardous drugs

6
New cards

What is the difference between USP 795 and 797?

Both pertain to compounding however:

  • 795: Non-sterile preparations

  • 797: Sterile preparations

7
New cards

What administration route is the most dangerous and why?

IV route because it bypasses all of the body’s natural barrier

8
New cards

When the pharmacists is verifying a compounded prescription what do they check for?

  • Whether or not there is matter that should not be there

  • The correct calculations were used

  • The right drug was used

  • The right diluent AND its volume was used

9
New cards

Harirforoosh said this would be on the test*** (easy though)

What are the different routes (and their abbreviations) and their injection site?

16
New cards

What is the bioavailability for the intramuscular route?

Anywhere between 0 and 1

17
New cards

Which one is easier to inject: intravenous or intramuscular?

Intramuscular (IM)

18
New cards

You want to administer a larger volume of a drug, which route would you use: intravenous or intramuscular?

Intramuscular (IM)

19
New cards

Which route has better absorption and why? Intramuscular or subcutaneous?

Intramuscular because the muscle tissue has more blood supply

20
New cards

Approximately how man mL can be administered intramuscularly?

2-5 ml

21
New cards

Is absorption for the subcutaneous route slow or fast?

Slow

22

  • Example: Penicillin injection and Penicillin for Injection?

  • [Drug] injection: A liquid perception that is a drug substance or a solution

  • [Drug] for Injection: Dry solids that, upon the addition of suitable vehicles, produce a solution for injection

24
New cards

True or False: Something can still be considered sterile even though it contains pyrogens

True: Sterile objects may still contain pyrogens

  • Common sterilization processes are inadequate to eradicate pyrogens

25
New cards

What is the most potent type of pyrogen?

Endotoxin

26
New cards

In terms of parenteral packaging, what do open & closed systems refer to?

Whether or not they allow the passage of air once they are opened

27
New cards

What is a small volume parenteral (SVPs)?

Usually stuff like preservative, antioxidants, excipients, etc.

  • Less than 100 mL

28
New cards

What is the most common source of contamination during sterile compounding?

Touch

29
New cards

What is USP 788?

Particulate Matter in Injections:

  • Limits the number of particles present in IV or IA injections

    • Because particles can’t be completely eliminated, just controlled

30
New cards

What ISO level is sufficient for sterile compounding?

At least 5

<p>At least 5</p>
31
New cards

What ISO level is achieved when you use a HEPA filter?

Maintains ISO class 5 air quality within the work zone

32
New cards

What is considered a low-risk level compounding?

Aseptic manipulations within ISO class 5 only involving transfer, measuring, and mixing with closed or sealed packaging

33
New cards

What risk level compounding is commonly seen in inpatient pharmacies?

Medium-Risk level

34
New cards

What is considered high-risk level compounding?

Using aseptic products to ultimately make a sterile product and the exposure of the sterile ingredients to air less than ISO class 5
