It is a state of response to a drug whereby drug taker feels compelled to use the drug and suffers anxiety when separated from it. |
ADDICTIONLos |
|
Loss of consciousness associated with an absence of response to pain |
ANESTHESIADr |
|
Drug that reduces anxiety; is a sedative |
ANXIOLYTIC |
|
Removal of the drug evokes unpleasant and possibly life threatening symptoms often opposite of the drug’s effect |
DEPENDENCE |
|
Induction of sleepoh |
HYPNOSIS |
|
Phase of sleep associated with rapid eye movements; most dreaming takes place in this stage |
REM SLEEP |
|
Reduction of anxiety |
SEDATION |
|
Reduction in drug effect requiring an increase in dosage to maintain the same response |
TOLERANCE |
|
These drugs produce dose dependent CNS depressant effects |
SEDATIVE-HYPNOTICS |
|
What are the subgroups of sedative-hypnotics? |
1.BENZODIAZEPINES 2. BARBITURATES 3. MISC. (Carbamates, alcohols, cyclic ethers) |
|
What are the mechanisms of Sedative-Hypnotics? |
1. Activation of GABA A which increases chloride influx, and activation of GABA B which increases Potassium influx 2. both Result in hyperpolarization |
|
What subgroup of sedative-hypnotics potentiate GABA? |
Benzodiazepines |
|
What subgroup of sedative-hypnotics increase the frequency of chloride channel opening? |
Benzodiazepines |
|
Benzodiazepines act through BZ receptors. What are these receptors and their function? |
BZ1 mediates sedation BZ2 mediates anti anxiety and impairment of cognitive functions |
|
This type of sedative-hypnotics prolong GABA activity |
Barbiturates |
|
They are drugs that have an inhibitory effect on the CNS |
Sedatives |
|
This type of sedative-hypnotics prolong GABA activity |

Sedatives |
|
Sedatives inhibits: |
1. Nervousness 2. Excitability 3. Irritability

|
What are the effects of low and high doses of SH? |
Low doses = calm or soothe the CNS High doses = + sleep |
