__ antagonists reduce positive symptoms of schizophrenia (hallucinations, delusions, disorganized speech/thinking, agitation, abnormal motor behavior)

Answer 6

D2

Question 7

2 dopamine pathways relevant to schizophrenia symptoms?

Answer 7

Mesolimbic –> overactivity –> positive symptoms

Mesocortical –> dysfunction –> negative and cognitive symptoms

Question 8

D2 antagonism of Nigrostriatal pathway induces __ symptoms

Answer 8

extrapyramidal

Question 9

D2 antagonism effects on prolactin levels?

Answer 9

increases prolactin levels

Question 10

the FGA’s primarily block __ receptors

Answer 10

D2 post-synaptic

block D2&raquo_space; 5HT2

Question 11

other receptors that FGAs also block (with varying potencies)?

Answer 11

Muscarinic –> anti-cholinergic SE’s
H1 receptors –> Sedation SE
a1 receptors –> Orthostatic hypotension, dizziness/syncope SE’s
D2 in nigrostriatal (movements) and tuberoinfundibular (prolactin)

can get risk of QTc prolongation and seizure activity

Question 12

Treatment for acute dystonia/akathisia/dyskinesia/parkinsonism-like SEs from using FGA’s? BIG STAR

Answer 12

Anticholingeric agents: Diphenhydramine (benadryl), benztropine (cogentin), and trihexyphenidyl

Question 13

what are the high potency FGAs that cause more movement (EPS) and endocrine effects (prolactin)?

Answer 13

Fluphenazine
Haloperidol
Thiothixene

Question 14

SGA’s block what receptors?

Answer 14

D2 post-synaptic AND 5HT2a

5-HT2a&raquo_space; D2

Question 15

what is the dual 5-HT2a/D2 theory?

Answer 15

5-HT2a antagonism increases DA transmission in nigrostriatal pathway –> may contribute to improved negative and cognitive symptoms via increased DA release in PFC, reduced EP SE’s

Question 16

This SGA is a D2 partial agonist, aids in dysregulation in mesocortical pathway

Answer 16

Aripiprazole

Question 17

Answer 19

2nd gen –> Clozapine, Olanzapine

Aripiprazole and Ziprasidone less associated with hypercholesteremia as 2nd gen drugs

Question 20

which gen more associated with EPS/tardive dyskinesia? drugs?
