NSG 552- PSYCHOPHARMACOLOGY QUESTIONS
AND ANSWERS VERIFIED LATEST UPDATE
The study of the use of psychotropic medications in the treatment of psychiatric
disorders:
Psychopharmacology
The study of what the body does to drugs:
Pharmacokinetics
The study of what the drugs does to the body:
Pharmacodynamics
Involves the absorption, distribution, metabolism and excretion of meds:
First Pass Metabolism (C.Y.P. 450)
Increase serum levels of other drugs that are substrates of that enzyme:
Enzyme inhibitors will slow down metabolism causing toxic levels
Decreases serum levels of other drugs that are substrates of that enzyme:
,Enzyme inducers cause fast metabolism and create subtherapeutic drug levels
Part of the brain that regulates powerful emotions such as fear, rage, sexual desires:
Amygdala
The relay station for sensory information:
Thalamus
Essential for maintaining homeostasis, controls basic needs such as sleep- wake
cycles:
Hypothalamus
This lobe is involved in executive functioning, high order planning, speech and
motivation:
Frontal Lobe/ Prefrontal cortex
Derived from Tryptophan and made in the Ralphe Nuclei:
Serotonin
Made in the Locus Ceruleus and involved in the noradrenergic pathways:
Norepinephrine
, 90% of serotonin receptors are found in the:
GI tract
Produced in the V.T.A. (Reward Pathway) and involved in the four major pathways:
Dopamine
Dopamine inhibits prolactin in this pathway:
Tuberoinfundibular
Increase dopamine in this pathway is associated with positive symptoms:
Mesolimbic Pathway
Decrease dopamine in this pathway is associated with negative symptoms:
Mesocortical Pathway
Decrease dopamine in this pathway produces motor symptoms:
Nigrostriatal Pathway
Main inhibitory neurotransmitter that induces calmness and relaxation:
Gamma- aminobutyric acid (GABA), Off switch
