1

what is a drug?

an external substance that acts on living tissue to produce a measurable change in the function of that tissue

2

what is the function of local anaesthetic?

prevent pain

3

what is the function of antimicrobials?

treat and prevent infection

4

what is the function of anxiolytics?

reduce anxiety

5

what is the function of analgesics?

reduce post op pain

6

what 3 things can drugs do?

simulate normal body communications
interrupt normal body communication
act on non-host organisms to aid body defences

7

how does the host communicate?

hormone messages
-general info to all tissues
neural messages
-targeted info for specific tissues

8

why may high doses of one hormone mimic the effects of another?

there is a lot of similarity in the structure of different hormones

9

what do thyroid hormones do?

balance body's metabolism

10

what happens when the level of thyroid hormones are wrong?

too much- hyperthyroidism
too little- hypothyroidism

11

what drugs can replace the missing active thyroid hormone?

T3 & T4
-thyroxine dose adjusted to correct level gradually

12

what are the symptoms of hypothyroidism?

cold intolerance
coarse skin
memory loss
slow pulse
low metabolism

13

what are the symptoms of hyperthyroidism?

rapid metabolism
high pulse
sweating and heat intolerance
anxiety & agitation
weight loss

14

what are the components of the autonomic nervous system?

sympathetic
-adrenaline
parasympathetic
-acetylcholine

15

how does the sympathetic ns control the HR?

adrenergic stimulation
speeds up heart via beta-receptors

16

how does the parasympathetic ns control the HR?

cholinergic stimulation
slows the heart via cholinergic receptors

17

what does topical mean?

drug applied to the tissue where it acts

18

what does systemic mean?

drug applied to whole organism

19

what does parenteral mean?

drug administered by injection

20

what does transdermal mean?

drug applied to skin for adsorption

21

what does subcutaneous mean?

injected into the tissues of the skin

22

what does intramuscular mean?

injected into muscle

23

what does intravenous mean?

injected into vein

24

what does transmucosal mean?

applied to mucosa for adsorption

25

give 4 examples of autonomic drugs

adrenaline
-beta agonist
atenolol
-beta blocker
-prevents actions of adrenaline release
pilocarpine
-cholinergic agonist
atropine
-cholinergic blocker
-prevent cholinergic stimulation of slowing HR
