Behavior final Flashcards
SSRI mechanism of action and uses?
blocks the reuptake of serotonin at the presynaptic terminal
used to reduce anxiety, aggression related to impulse control or anxiety, OCD, urine marking/ inappropriate urination
Examples of SSRIs
Fluoxetine (Prozac), Sertaline (Zoloft), Paroxetine (Parxil), Reconcile?
SSRI side effects
GI upset- Fluoxetine can cause anorexia, Paroxetine can cause constipation, Sertraline can cause vomiting and diarrhea, lethargy, hyperexcitability (paroxetine)
Azapirones (Buspirone/ BuSpar) mechanism of action and uses
Non-sedating anxiolytic, partial agonist of serotonin and dopamine, used to manage urine marking/ soiling, mild chronic fears and anxieties ex. fear of humans and separation anxiety
Benzodiazepines mechanism of action and uses
Increases binding of GABA by increasing the rate of channel opening
Used for acute management of anxiety, manages fear without aggression and phobias
Benzodiazepine side effects
hepatic necrosis in cats, sedation, muscle relaxation, hyperphagia, behavioral disinhibition, ataxia
Examples of Benzodiazepines
Diazepam, Alprazolam, Clonazepam, Lorazepam, Chlroazepate
Monoamine Oxidase Inhibitors mechanism of action and uses
prevent breakdown of monoamines (dopamine, adrenaline norepinephrine, serotonin), antidepressant, inhibition of MAO-B used to prevent neurodegenerative processes and improve cognitive function
Example of a selective MAO-B drug
anipryl
Which is more sedating TCAs of MAOs
TCAs
TCA mechanism of action and uses
Inhibits reuptake of serotonin AND norepinephrine and are antidepressants
Examples of TCAs
Amitriptyline (Elanil), Clomipramine (Anafril)
Side effects of TCAs
sedation and GI upset, dry mouth (dental disease), mydriasis, decrease tear production, urinary retention, dizziness, vasoconstriction, smooth muscle contraction, arrhythmias, stroke,
Alpha-2 agonists mechanism of action and uses
Inhibits release of NE and decreases sympathetic tone, centrally acting (locus ceruleus), reduces fear and panic responses, decreases blood pressure, heart rate and peripheral resistance, blocks pain signals, in CNS works as anxiolytic, sedative, and analgesic
Examples of alpha-2 agonists
Clonidine and Dexmedetomidine (SILEO)
what are 3 uses for clonidine
Treatment of fear and anxiety, as an adjunctive for pain, and used for hypertension and Glaucoma.
What is Dexmedetomidine (SILEO) approved for?
Use of noise aversion in dogs
What is the mechanism of action of SARIs and what is an example of one
Antagonizes serotonin 2 reuptake, alpha-1 adrenergic antagonism, and antihistamine properties, trazodone
Antipsychotic (neuroleptic) agents (aka Acepromazine) mechanism of action and uses
blocks dopamine receptors in basal ganglia and limbic system and some block serotonin receptors too- depresses the reticular activating system and regions of brain that control thermoregulation, basal metabolic rate, emesis, vasomotor tone, cause behavioral quieting, antiemetic, but no anxiolytic effects!
Acepromazine side effects
inability to control movements and may cause aggression use caution if animal has history of seizures, hepatic disfunction, renal imbalance, cardiac disease, are young or geriatric, pregnant, giant breed, boxers, and greyhounds
