Question:

Blocks Noradrenergic, Cholinergic and Histaminergic receptors effects

Answer:

-Noradrenergic - Prolonged atrial + ventricular conduction and refractory; decrease cardiac contractility. Low potency is worse than high potency.Prolonged QTc and Torsades/sudden death

Anti-Alpha 1 effects: Postural hypotension

-Cholinergic: Dry mouth, constipation, urinary retention, agitation,

disorientation, hallucinations, seizures, high fever, dilated pupils, stupor, coma - Physostigmine to treat, w/ caution

Question:

Ways Neuroleptics Affects 4 pathways: ---Mesocortical, Mesolimbic,

Nigrostriatal, and Tuberoinfundibular pathways

Answer:

Mesocortical - worsen negative symptoms of cognitive impairment, blunted emotions, social ...

Mesolimbic - Antipsychotic effects block hallucinations, delusions, and agitation (positive sx) - what we want!

Nigrostriatal - EPS: Parkinson-like S.E. and Tardive Dyskinesia

-Acute dystonia - (hours to days after initiation) - acute muscle contractions -Akathisia - (days to weeks ...) restless, jittery, like a caffeine rush -Parkinsonism - (weeks to months ... ) tremor, cog-wheel rigidity, hypokinesia -Tardive Dyskinesia - (months to years ...) hyperkinesis, perioral movements -TD is IRREVERSIBLE - risk increases 3% every year patient is on the drug

Tuberoinfundibular- Dopamine acts as Prolactin-inhibiting factor; D2 block increases prolactin levels = gynecomastia, sexual S.E., osteoporosis, amenorrhea, galactorrhea
