Psychopharm Final Flashcards
MOA of common antidepressants?
inhibit serotonin and NE reuptake
Stimulate non-adrenergic and dopamine activity
Alpha 2 antagonism of nor-adrenergic and seratonergic neuron
ADR of antidepressants DDRI
SSRI: insomnia appetite change Nausea Dry mouth Headache sexual Dysfx
ADR of antidepressants TCA
anticholinergic: dry mouth/constipate/urinary retention/blur vision
Histaminic: Sedation/weight gain
Alpha 1 adrenergic blockade: orthostatic hypotension/ falls
there can be arrhythmias and OD so dont combine be careful..
Widended QRS?
overdose
What is serotonin syndrome?
agitation diaphoresis tachycardia autonomic nstability clonus tremor hyperreflexia**** increase bowel sounds
everything mostly in LE.
Management of serotonin syndrome?
Discontinue drug Supportive care (icu) Control agitation 5-HT2A antagonist Control instability and hyperthermia
what dont you manage serotonin syndrome with?
Propranolol
Bromocriptine

altered mental status muscle fasciculation stupor seizure coma hyperreflexia

Neurobiology of schizophrenia?
Dopamine hyperactivity in mesolimbic pathway
Faulty NMDA synapse on GABA interneurons in PFC. cause overstimulation of b brainstem neurons to mesolimbic.
side effects of D2 receptor blockers
more likely to cause movement problems and hyperprolactinemia
DWaht are 1st gen anti-psychotics?
D2 blockade drugs targets mesolimbic (hallucination) and mesocortical (speech/motor)
can cause movement problems and hyperprolactinemia
What are 2nd gen anti-psychotics?
work at D2 and serotonergic receptors
Side effects: cause HTN Metabolix syndrome Diabetes Wt gain
Neuroleptic Malignant syndrome?
reaction to neuroleptic meds
rigidity
Hyperthermia
Autonomic instability
Changes in LOC
