Seratonin and dopamine Flashcards
busprione
5HT-1A partial agonist used to treat anxiety disorders, can cause drowsiness, initial depression
sumatriptan
5HT-1D agonist used in treating migraines by causing cerebral vasoconstriction and an inhibition in the release of inflammatory mediators
fluoxetine
SSRI that increases the amount of serotonin in the synaptic cleft
functions to increase mood/used in depression
takes a couple of weeks to work because it non selectively binds its own 5HT-1A receptors, resulting in negative feedback which desensitizes over time
sertraline
SSRI that increases the amount of serotonin in the synaptic cleft
functions to increase mood/used in depression
takes a couple of weeks to work because it non selectively binds its own 5HT-1A receptors, resulting in negative feedback which desensitizes over time
trazadone
Seratonin antagonist-reuptake inhibitor
5HT-2C/2D antagonist that has anti-anxiety effects of sertraline without its increased alertness and erectile dysfunction effects
also has reuptake inhibitor capabilities of sertraline
risperidone
5HT-2A/D antagonist that lowers dopamine release in the mesolimbic pathway but increases dopamine release in the mesocortical pathway used in schizophrenia and psychosis
ondansetron
5HT-3 antagonist responsible for inhibiting chemo induced nausea
blocks the activity of these receptors in the gut, leading to their decreased relay of nausea information to the brain
mosapride
5TH-4 agonist to promote GI peristalsis
not used due to contraindication of long QT syndrome leading to fatal arrhythmias
cisapride
5HT-4 agonist to promote GI peristalsis
not used due to contraindications long QT syndrome resulting in fatal arrhythmias
LDOPA
precursor to dopamine
given to Parkinson’s patients…it can cross BBB, dopamine cannot
can cause arrhythmia and dyskinesia
carbidopa
an AADC (LDOPA converting enzyme) inhibitor that inhibits dopamine synthesis useful because dopamine is rapidly degraded in the body and cannot cross the BBB given with LDOPA in treating Parkinson's
bromocriptine
dopamine receptor agonist in the basal ganglia used in treating Parkinson’s
selegiline
selective MOA-B antagonist (can inhibit MOA-A at higher doses) used in Parkinson’s
tolcapone
COMT antagonist that enhances the effects of LDOPA used in Parkinson’s but can cause liver failure
haloperidol
D2 antagonist used in schizophrenic and psychosis patients
