Chapter 17 CNS Stimulant drugs Flashcards
Amphetamines
CNS stimulants that produce mood elevation or euphoria, increase mental alertness and capacity to work, decreased fatigue and drowsiness, and prolong wakefulness
Analeptics
CNS stimulants that have generalized effects on the brain stem and spinal cord, which in turn produce an increase in responsiveness to external stimuli and stimulate respiration
- Used to treat ADHD
- Reverse anaesthesia-induced respiratory depression
Anorexiants
Drugs used to control or suppress appetite, that also stimulate the CNS
- Used to treat obesity
Attention deficit hyperactivity disorder (ADHD)
Syndrome affecting children, adolescents, and adults that involves difficultly in maintaining concentration on a given task, hyperactive behavior, or both
- Usually begins before age 7 and is more common in boys
- Often accompanied by anxiety, mood disorders
-
Cataplexy
A condition characterized by abrupt attacks of muscular weakness and hypotonia triggered by an emotional stimulus such as joy, laughter, anger, fear, or suprise
CNS stimulants
Drugs that stimulate specific areas of the brain of spinal cord
- Used to treat ADHD, narcolepsy, obesity, migraine, and respiratory depression syndrome (affects neonates)
- Adverse effects include Palpitations, tachycardia, hypertension, angina, dysrhythmias, nervousness, restlessness, anxiety, insomnia, nausea, vomiting, diarrhea, dry mouth, increased urinary frequency, others
-
Migraine
A common type of recurring painful headaches characterized by a pulsatile or throbbing quality, incapacitating pain, and photophobia
- Assosiated symtpoms include nausea, vomiting, phonophobia
- CNS stimulants that work the best are the serotonin agonist
Narcolepsy
Syndrome characterized by sudden sleep attacks, cataplexy, sleep paralysis, and visual or auditory hallucinations at the onset of sleep
- episodes may last a few minutes to one hour
Serotonin receptor agonists
A new class of CNS stimulants used to treat migraines that work by stimulating 5-HT1 receptors in the brain
Sympathomimetic drugs
CNS stimulants such as noradrenergic drugs (and to a lesser degree dopaminergic drugs) whose actions resemble or mimic those of the sympathetic nervous system
Anti- ADHD
Stimulate the areas in the brain responsible for mental alertness and attentiveness
Anti-narcoleptic
Increases mental awareness
Anti-migraine
Cause vasoconstriction in cerebral arteries and normally reduce or eliminate headache symptoms
Caffeine
- Found in OTC drugs, combination prescription drugs, foods
- Many uses including neonatal apnea, respiratory depression in adults, enhance effects of analgesics and migraine medications, and to stimulate CNS
