Question 5

Answer 5

Study of how drugs enter the body, are absorbed, distributed, metabolized and exit the body (excretion)

Question 6

Absorption of Drugs, what it depends on

Oral drugs

Answer 6

Absorption - a process by which a drug enters systemic circulation in order to provide a desired effect
Depends on - SA, blood flow, concentration drugs in solution move from area of high concentration to low concentration, compatibility some drugs interact with other drugs to form insoluble precipitates (no absorption happens)
Oral Drugs - are absorbed in the small intestine by the mucosal lining, those in a liquid form are processed more quickly than tablets or capsules, and are often given in larger doses

Question 7

Distribution of Drugs - what is it and 3 factors

Answer 7

How the drugs travels through the blood stream and outwards to the target tissue and site of action

1. Regional blood flow - the amount of blood supplied to that organ/area
2. Cardiac output- amount of blood pumped by the heart per minute
3. Drug reservoirs- drug accumulates that are bound to specific sites such as fat/bone tissue and plasma. Drugs must cross barriers to be effective

Question 8

Metabolism of drugs - what is it, factors that affect it

Answer 8

Chemically changes a drug into a metabolite that can be excreted by the body
We do not want drug effects to be permanent
Primarily the responsibility of the liver (Kinsey’s, lungs, plasma, intestinal mucosa play a role too)
Factors that affect it - age, overall health, time of day, emotional status and mental health, presence of other drugs in the body, genetic variations and disease processes/states

Question 9

Answer 11

Question 17

Enteral Drug Administration

- 2 routes

Answer 17

Applies to med administered directly into the GI tract via oral or rectal route
Oral is most common
Used for large dose when slower absorption and longer duration of drug activity are required
Rectal - dose is unreliable, placed directly into the rectum, given when the pt is nauseated or can’t take oral meds

Question 18

Sublingual or Buccal Drug Administration

Answer 18

These are absorbed into the blood through the oral mucosa
