Anti-psychotics Flashcards
SHARK: grouped concepts
~ notes have in bold
* i think will be high yield
hurah
concept: cause of positive psychotic symptoms and goal of how we wnat to treat them
increased dopamine in the mesolimbic system; we want to treat them by DECREASING DA effects -> block D2 receptors
concept to understand s/e of treatment: Describe the mesolimbic pathway
midbrain to limbic system = emotional behavoiurs
hyperactivity = positive psychotic symptoms
**block D2 here to stope psychosis
concept to understand s/e of treatment: nigrostriatal pathway
substantia nigra to basal nigra = motor movements
when block D2 here - extrapyramidla reactiosn = funy motor movemetns like parkinson disease and such
concept to understand s/e of treatment: mesocortical pathway
midbrain to prefrontal cortex = if reduced activity then have negative and cognitive symptoms
if block D2 here get worse cognitive and negative symptoms
concept to understand s/e of treatment: tuberoinfundibular pathway
hypothalamus to anterior pituitar = DA inhibits prolactin
block D2 - prolactinema = galacthorrhoea
Name the CLASSIC antipsychotics
CFHT
-AZINEs
chlorpromAZINE
fluphenAZINE
haloperidol
thioridAZINE
Name the ATYPICAL antipsychotics CROQ-ZAP -PINE -DONE and randoms
clozaPINE risperiSONE olanzaPINE/aux-lanse epine quetiaPINE ziprasiDONE aripiprazole paliperiDONE
aka if a word looks like you are having a hallucination assume its a this
Name the high potency classic antipsychotics ie the ones who will cause the most extrapyramidal reactions (inhibition of the nigrostrial pathway)
C
FluphenAZINE
Haloperidol
T
Name the low potency classic antipsychoticsc ie the drugs that will cause the least extrapyramidal reactions (lower inhibition of the nigrostiatal pathway)
ChlopramAZINE
F
H
ThioridAZINE
Which classic antipsychotics are more likely to cause sedation and postural hypotension
the low potency drugs ChlorpramAZINE F H ThioridAZINE
Describe receptors affected by ClozAPINE
atypical antipsychotic CROQ-ZAP
* high affinity for D1, D4, D4, 5HT2, muscarinic and alpha adrenergic
PROTOTYPE
~*~Special facts about Resperidone
5HT2 blockage more than D2
MOST LIKELY TO CAUSE EPR
Atypical antipsychotics least likely to cause EPR
ClozAPINE R O QuetiAPINE Z A P
Describe receptors affected by Aripiprazole
partial agonist at D2 and5HT1a
antagonist at 5HT2a
