Behavior Modifying Drugs Flashcards
1
Q
Benzodiazepines
A
- amplify the effects of GABA causing patients to be less reactive to surroundings and less responsive to provocative stimuli
- cats becomes excessively friendly, sleepy or uncoordinated
- interupt learning and short term memory thus not to be use in conjunction for behaviour modification (Develop physiologic and behavioural dependency)
- USES: sporadic events that cause pain or anxiety (thunderstorms, fireworks, etc)
- include diazepam, alprazolam, chlordiazepoxide, flurazepam, clorazepate, oxazepam and triazolam.
2
Q
Diazepam
A
VALIUM
- benzodiazepines (GABAergic)
- -cause idiosyncratic, fulminant hepatic necrosis in cats given oral diazepam
- measure baseline ALT and AST before therapy and after started
3
Q
Alprazolam
A
XANAX
- benzodiazepine (GABAergic)
- Good for aggression
- 3-5 weeks to get effect
- high doses can cause profound lethargy and incoordination
4
Q
Chlordiazepoxide
A
LIBRIUM
- benzodiazepines (GABAergic)
- appetite stimulant and anxiolytic effects in cats
5
Q
Flurazepam
A
DALMANE
-appetite stimulant and anxiolytic effects in cats AND dogs.
6
Q
Clorazepate
A
TRANXENE
- benzodiazepine (GABAergic)
- hydrolysed to diazepam metabolite (long half life)
- good for thunderstorm phobias, compulsive grooming and wool sucking
7
Q
Oxazepam
A
SERAX
- benzodiazepine (GABAergic)
- appetite stimulant in cats and dogs
8
Q
Triazolam
A
HALICON
-aggession in cats
9
Q
Buspirone (Buspar)
A
-partial serotonin agonist
and dopamine receptor antagonist.
-causing them to be less anxious and more social in social situations
-good for cats for txing urine marking/spraying
-no dependence developed
-2-4 weeks for effect
-may cause aggression
10
Q
Tricyclic antidepressants (TCAs)
A
- inhibit serotonin and NE reuptake and relieve primary or secondary anxiety
- block muscarinic, histaminic and adrenergic receptors
- modulate glucocorticoid receptor and enhance GR-mediated gene transcription (clomipramine best at this)
- inhibit steroid transporter than extrudes cortisol.
- used as antidepressants and anxiolytics and to treat inappropriate elimination, stereotypes, narcolepsy and incontinence.
- get relapse off drug tho
- couple weeks to get steady state
- gluconuration in liver to metabolize (cats sensitive)
- narrow therapeutic index
- toxicity at low doses
- profound cardiac effects
- IV lipid emulsion effective antidote for overdoses in dogs and cats.
- imipramine, amitriptyline, clomipramine
- long elimination HL so need to do washout
11
Q
Imipramine (Tofranil)
A
- TCA
- used for separation anxiety and aggression in dogs
- used to treat narcolepsy in dogs and horses
12
Q
Amitriptyline (elavil)
A
- TCA
- used for inappropriate urination in cats
- some anti inflammatory activity (useful when feline lower UT disorder is causing problem)
13
Q
Clomipramine
A
ANAFRANIL, CLOMICALM
- separation anxiety in dogs mainly
- useful in treating phobias and panic disorders and inappropriate urination in cats
14
Q
Selective serotonin reuptake inhibitors (SSRIs)
A
- specifically inhibit the serotonin reuptake
- fewer anticholinergic effects and less cardiotoxicity than TCAs’
- fluoxetine, paroxetine, sertraline and fluvoxamine
- long elimination HL’s thus need to do washout
15
Q
Fluoxetine
A
RECONCILE (prozac)
- -SSRI
- inhibits reuptake of serotonin and up regulates GABA receptors
- decreases aggression (due to elevated serotonin)
- racemic mixture (S-enant better SSRI)
- effective in reducing spraying in cats
- controls separation anxieity, dominance aggression and txing acral lick granulomas in dogs
