What to know about FGAs?
Binds to D2 receptor, Movement disorders (acute dystonias, akathisia, pseudo-parkinsonism (EPS), Tardive dyskinesias. Also off-target binding (more common in low potency agents)–> Anticholinergic, histaminergic (sedation, orthostasis:alpha-blockade).
What to know about SGAs?
Activity at 5-Ht receptors in addition to dopaminergic activity. Side effect profile more heterogenous, Less EPS. Increased risk of metabolic effects, weight gain, diabetes mellitus, dyslipidemias.

Clozapine and Olanzapine, then FGAs, then Quetiapine.
Which SGAs have the lowest weight gain potential?
Lurasidone, Aripiprazole, Cariprazine.
Which SGAs affect glucose intolerance most?
Clozapine and Olanzapine, asenapine, iloperidone, aripiprazole is lowest.

What are the treatment guidelines for schizophrenia?
1st line- most prefer SGAs (some exclude olanzapine due to metabolic effects, some include FGAs)
2nd line - SGA or FGA (only an FGA if an SGA was tried first), some include clozapine
3rd line - Clozapine is 3rd line (exception if patient is suicidal), this is good for treatment resistant
What to know about Clozapine?
1st SGA considered to be Atypical. Indicated to reduce suicidal thoughts, preferred in treatment resistant schizophrenia, intensive monitoring program required. Agranulocytosis–> Every week for 1st 6 months, ANC <1000, interrupt treatment, ANC <500, stop, don’t rechallenge.
What are the long acting injectables?
Aripiprazole, Fluphenazine, Haloperidol, Olanzapine (REMS drug), Paliperidone, Risperidone.
Which SSRI has the longest half life?
Fluoxetine
Which SSRIs is activating?
