Stimulants Flashcards
slow messages between the body and brain
Depressants
Signals from the eyes and other senses reach the brain slowly.
Depressants
Heart rate drops, leaving the body with less energizing oxygen.
Depressants
Breathing rate decreases: risk of lung infections rises.
Depressants
Messages to muscles are siower; arms and legs can’t move well.
Depressants
create fake messages in the brain, telling the body that it’s under stress
Stimulants
Blood to skin decreases: the body is lass able to cool itself. Overheating is a risk
Stimulants
Heart rate speeds up. Blood vessels to the heart constrict.
Stimulants
the liver releases sugar into the blood, reducing the body’s energy stores.
Stimulants
if real stress occurs, the body won’t e able to respond.
Stimulants
Numerous drugs can stimulate the CNS, but medically approved use of these drugs is limited to the treatment of
ADHD, narcolepsy, respiratory distress, obesity
These drugs can calm hyperkinetic children and help them focus on one activity for a longer period
CNS Stimulants
they redirect and excite arousal stimuli from the RAS
CNS Stimulants
Active as both cortical and RAS stimulants possibly by increasing catecholamine release from presynaptic neurons.
CNS Stimulants
are able to increase stimulation of postsynaptic neurons.
CNS Stimulants
the paradoxical calming effect of these drugs in hyperkinetic children is thought to be related to the increased stimulation of the immature RAS leading to an ability to be more selective in response to coming stimuli.
CNS Stimulants
Indication of CNS Stimulants
for the treatment of ADHD and narcolepsy
True or False
CNS are used to control behavior with dementia

Administer CNS Stimulants before ___ to avoid ________
6pm; insomnia
for CNS Stimulants, monitor for
CBC, weight, ECG
in monitoring for patien taking amphetamines, report for
extreme restlessness/insomnia
amphetamine like drugs
methylphenidate
atomoxetine
modafinil
produces cns and respiratory stimulation with weak sympathomimtic activity
amphetamine like drugs
contraindications/cautiong for amphetamine like drugs:
hyperexcitable states
Adverse reactions of
Amphetamine-Like Drugs
Hyperactivity
Insomnia
Restlessness
Tremors
Anorexia
Sudden death
Analeptics
caffeine
theophylline
Affects brainstem, spinal cord, and cerebral cortex.
Relaxes bronchial smooth muscle, increases heart rate and blood pressure, stimulates respirations.
Analeptics
use for newborns with apnea
Analeptics
Respiratory CNS Stimulants
Doxapram
Low dose of the drug stimulates carotid receptors; higher dose of the drug stimulates respiratory center in the medulla which produces,generalized CNS stimulation
Doxapram
Preventive treatments for Migraine
beta blockers
anticonvulsans
tricyclic antidepressants
