Etiology of anxiety disorders
|
Indentification with anxious patient
Conditioned fear Hyperactive arousal systems -NE - locus coeruleus -Glutaminergic Deficient braking system -Serotonin -GABA Panic disorder - abnormal CO2 response |
|
Agoraphobia
|
Anxiety about being in situations from which escape might be difficult or embarrassing and help might not be available
|
|
Specific (simple) phobia
|
Marked, persistent, unreasonable fear of circumscribed objects or situations
-Animal -Natural -Situational -Blood injection - familial |
|
Social phobia (social anixety disorder)
|
Anxiety about hummilating oneself in social or performance situations
|
|
Benzodiazepine use in anxiety
|
Acute anxiety - especially cardiac pt.
Initial treatment of anxious depression Treatment of chronic anxiety in patients who do not do well with other treatments |
|
Pharmacology of benzos
|
Changes conformation of GABA receptor such that it increases GABA binding (lower Km)
Leads to increased Cl- --> hyperpolarization |
|
Inverse agonist
|
Acts on a receptor but has the reverse action as the typical agonist
|
|
Benzo receptor subtype effects
|
Type 1 - A
Type 2 - SCAMP Type 3 - WD |
|
Potency
|
High potency - smaller dose, more receptor occupancy, more intense withdrawal
Low potency - higher dose, less intense withdrawal |
|
Lipid solubility
|
High - drug gets into brain fast, perferable if rapid onset is needed, increased risk of dependence (buzz feeling)
Low - get into and leave brain slowly, slow onset of action, effect lasts longer after a single dose, lower abuse potential |
|
Half life
|
Long - less frequent dosing, more accumulation, slower onset of withdrawal
Short - dosed more frequently, less accumulation, faster onset of withdrawal |
|
Benzo metabolic pathways
|
Complex - diazepam, chlordiazepoxide, flurazepam
Simple - midazolam, alprazolam, lorazepam, oxazepam |
|
Bezodiazepine side effects
|
Sedation
Psychomotor impairment Interdose withdrawal Interactions - EtOH |
|
Benzo withdrawal features
|
Agitation
Confusion Delirium Tremor Myoclonus Hyperreflexia Hyperpyrexia Seizures |
|
BZD-1 receptor selective agents
|
Quazepam
Zolpidem Zalepon Less sedation, impairment, withdrawal |
|
Partial agonist
|
Not quite as good at activation as natural ligand
High natural ligand + PA --> decreased effect Low natural ligand + PA --> increased effect |
|
Nonselective parital BZD receptor agonists
|
Zopiclone
Eszopiclone Weaker acute effect than benzos, less dependence and withdrawal |
|
Alternatives to BZD agonists for anxiety
|

|
