High potency vs Low potency
-Why is this important?
-Drugs for each category
High potency neuroleptics have more extrapyramidal side effects and less anticholinergic side effects (delusional, dry as a bone, etc.)
High potency: haloperidol, fluphenazine, thiothixene

Low potency: more likely to have anticholinergic side effects, less likely to have extrapyramidal side effects

Low potency: thioridazine, chlorpromazine
Block D2 receptors to inc cAMP

Extrapyramidal system side effects--muscle spasm, neck twisting, dystonia, tardive dyskinesia

Negative: diminishment/absence of normal function (flat affect, poor grooming)

How do atypical antipsychotics differ from the typical antipsychotics?
