administration until the parent drug and all metabolites leave the body
Pharmacokinetics concepts - Correct Answerabsorption
distribution
metabolism
excretion
Flockhart Table - Correct Answerdrug interactions that are mediated by cytochrome P450
enzymes
comprehensive list of drugs and the interactions related to the cytochrome P450 system
client factors that impact the effect of psychotropic medications - Correct Answer-age
-diet
-smoking status
-other prescribed medications
-over-the-counter medications
*all impact drug metabolism
Neurotransmitters - Correct Answerchemicals released by neurons to send communication
across synaptic clefts to other neurons
-impact human emotion and behavior
, Many psychiatric disorders and client symptoms occur from an excess, deficiency, or imbalance
of _________ - Correct Answerneurotransmitters
Neurotransmission: - Correct Answerthe chemical transmission of information between neurons
and their target cells
-the chemicals, or neurotransmitters, are released from their transport vesicles to bind with
receptor sites to perform their duties, which are excitatory or inhibitory
-neurotransmitter then either returned and stored for future use (reuptake) or inactivated and
dissolved by enzymes
Excitatory neurotransmitters: - Correct Answerincrease the likelihood that the neuron will fire
an action potential
inhibitory neurotransmitters: - Correct Answerdecrease the likelihood that a neuron will fire an
action

-acetylcholine
monoamines
-norepinephrine, dopamine, serotonin, histamine
amino acids
