Q

what are the 5 things that routes are determined by

A
  1. Ease of administration - ex. age
  2. Patient adherence - ex. level of consciousness
  3. Desired onset of action - ex. immediate vs time delayed
  4. Local vs systemic distribution - ex. intra-articular vs oral
    anti-inflammatories
  5. Drug properties - ex. insulin is injected b/c it is
    destroyed in the GI tract

16
Q

true or false

Execrise increases absorption of medicine

A

false

17
Q

true or false

liquid delays up absorption, food in stomach speeds absorption

A

false

Liquids speed it up and food slows it down

18
Q

what is the first pass effect

A

Drug is absorbed in GI tract and carried to

the liver before it reaches the blood stream

19
Q

true or false
Drugs are not evenly distributed throughout
body

A

true

20
Q

what does high volume of distribution and low plasma concentration cause

A

drug

more greatly distributed in extravascular spaces

21
Q

does higher body weight equal higher or lower volume fo distribution csusign lower or higher blood concentration

A

Higher body weight equals higher volume of

distribution and therefore lower blood concentration

22
Q

what is the site and action of a drug (explain site)

A

The “site” is the target receptor on the cell

surface or inside a specific cell type

23
Q

what is the site and action of a drug (explain action)

A

The “action” is biological response caused

by the active drug or metabolite
