Antidepressant Agents Flashcards
Depression is
A disorder of the mood, not a disorder of thought or reality (psychosis)
Depression is related to what NT imbalance and antidepressant drugs help to keep these NT in the synapse longer
NE and Serotonin
Antidepressant Drugs Action (pharmacodynamics)
Block the re-uptake transporter for NE, DA and Serotonin to allow for excess NT to accumulate in the synapse, this leads to down-regulation of post synaptic receptors leading to relief from depression
Non selective Re-uptake Inhibitors Include
Tricyclic Antidepressants (TCA) (First Generation) Heterocyclics (2nd Generation)
Selective Reuptake Inhibitors Include
SSRI’s
What 2 compounds should never be consumed w/ antidepressant meds but also act at the same re-uptake transporter resulting in elevated NT levels
Amphetamine and Cocaine
Tricyclic Antidepressants block
DA and NE uptake back into synaptic terminal
Examples of Tricyclic Antidepressants Meds
Tofranil (Tofer from that 70’s show makes you feel better)
Elavil
Side effects of Tricyclic Antidepressants
Dry Mouth, urinary retention, tachycardia, sedation, orthostatic hypotension, dizziness, decreased libido (these drugs also bind to ANS receptors hence these effects)
Heterocyclic Antidepressants Adverse effects include
Sedation, Weight gain, dizziness, pseudoparkinsonism (remember that first generation deals more w/autonomic involvement adverse effects)
Second Generation Heterocyclic Antidepressants Include
Asendin (Ascend your mood upwards/ascend to “2nd” floor)
Wellbutrin (Make you feel well “2nd” you take them_
Third Generation Heterocyclic Antidepressants
Cymbalta
Remeron “Remember (remeron), Cymbalta can help”
SSRIs block what
re uptake of serotonin at the synapse
SSR’s compared to TCA’s are
more specific and have fewer side effects, lack of cardiotoxic effects, have a higher safety index
SSRI meds incldue
Prozac, Paxil, Zoloft
