Pharmacokinetics - correct answer -the study of what happens to a drug from the time of
administration until the parent drug and all metabolites leave the body
Pharmacokinetics concepts - correct answer -absorption
distribution
metabolism
excretion
Flockhart Table - correct answer -drug 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

Neurotransmitters - correct answer -chemicals 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 answer -neurotransmitters
Neurotransmission: - correct answer -the 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 answer -increase the likelihood that the neuron will fire
an action potential
inhibitory neurotransmitters: - correct answer -decrease the likelihood that a neuron will fire an
action
neurotransmitters that most impact mental health can be classified into four major categories: -
correct answer -cholinergics
-acetylcholine
monoamines
