Q

Drug Approval Process

A
  1. Animal studies: tested on at least 2 animal species
  2. Clinical Trials:
    a. Phase 1: tested in healthy volunteers to compare with animal data, safe doses
    b. Phase 2: 50-300 patients in a double blind studies
    c. Phase 3: Larger patient group (1000s) lasting several years to evaluate efficiency and side effects
    d. Phase 4: “New drug submission” to HPFB (Health Products and Food Branched)

24
Q

Result from the direct application of a drug to a tissue

A

Local Effect

25
Q

Occur after the drug is absorbed by any route and distributed by the bloodstream. Involves more than 1 organ

A

Systemic Effects

26
Q

Drug Action Dependant on:

A
  • The patient
  • The dose
  • The route
  • Drugs metabolic rate
27
Q

Anywhere along the GI tract
- Oral (PO)
- Rectal (RR)
- Orogastric/Nasogastric (OG/NG)

A

Enteral Route

28
Q

Any route other than GI tract
- Injectable (IV, IM, SC)
- Inhalation (Neb, IN)
- Mucous Membrane (SL, Buccal)
- Skin (transdermal, topical)

A

Parenteral Route

29
Q
  • Most rapid effect
  • Most dangerous route
  • Drugs go directly into the bloodstream and to target organs
  • Known quantity over know period of time
  • Dangerous because it delivers the entire dose at once
A

IV Route

30
Q
  • Becoming increasingly popular in serious patient presentations like cardiac arrest
  • Rate and time of onset identical if not better than IV
A

Intraosseous Route (IO)

31
Q
  • Deltoid, Vastus Lateralis or into upper outer quadrant of the gluteus
  • Takes longer to act, longer duration of action
  • Must be absorbed from the muscle into the bloodstream
  • Need adequate perfusion
A

Intramuscular Route (IM)

32
Q
  • Injected into the subcutaneous tissue beneath the skin
  • Absorbed more slowly
  • Peak effect within about 30 minutes
  • Upper outer arm, anterior thigh, or abdomen
  • Need adequate perfusion
A

Subcutaneous Route (SC)

33
Q

Advantages of Enteral Route

A
  • Simple
  • Safe
  • Time released
  • Low potential of infection
34
Q

Disadvantages of Enteral Route

A
  • Slow rate of onset
  • cannot be given unconscious or nauseated unless rectal
  • Absorbed dosage may vary significantly because of actions of digestive enzymes or condition of GI tract
35
Q

Advantages of Parenteral Route

A
  • Rapid onset
  • Can be given unconscious or nauseated
  • Absorbed dose and action more predictable
36
Q

Disadvantages of Parenteral Route

A
  • Administration more painful and difficult
  • Side effects more severe
  • Higher potential for infection
37
Q

Rate of Absorption for Topical, Oral and Rectal Routes

A

Topical: hours-days
Oral: 30-90 mins
Rectal: 5-30 mins (unpredictable)

38
Q

Rate of Absorption for SC, IM, SL tablet, SL injection

A

SC: 15-30 mins
IM: 10-20 min
SL Tablet: 3-5 min
SL injection: 3 min

39
Q

Rate of Absorption for Inhalation, Endotracheal, IO, IV, Intracardiac

A

Inhalation: 3 min
Endotracheal: unkown; unpredictable
IO: 60 sec
IV: 30-60 sec
Intracardiac: 15 sec

40
Q

41
Q
