Name 3rd Gen antidepressants? | Serzone,Cymbalta,Effexor |
How do Tricyclic Drugs work? | Block reuptake of norepinephrine and to a lesser degree of serotonin into the presynaptic cell. |
Side Effects of Tricyclic antidepressants? | Due to block other receptors such as:
Muscarinic receptors also-ANTICHOLINERGIC s/e:blurred vision,urine retention,constipation,
A1:blocks the pressor response necessary to avoid Orthostatic Hypotentsion
Ratio to toxic dose is very low: Death |
How SSRI's work? | BLock the reuptake of serotonin back into the presynaptic space, decrease destruction of transmitter and there is more serotonin at synapse for the postsynaptic cell. |
Key Points about SSRI's | -Do not block other receptors-less side effects
-ONLY effective in mild or moderate depression
-good choice for impulsive or suicidal bc no risk of lethal overdose
-4-6 weeks before meds take effect,monitor suicide, maybe more energized but still have |
Side effects of SSRI's | Nausea- take with food
weight gain- least amount compared to others |
How MOAi's work? | inhibits the ability of the enzyme to destroy the monoamines:norepinephrine,dopamine,serotonin. Eventually leads to presynaptic,synaptic,and postsynaptic concentrations of these neurotransmitters. |
Key points of MAOi's | -MAO is present in the liver cells as well as monoamine-releasing neurons.
-Inactivation of hepatic MAO by MAO-inhibiting drugs can lead to potentially fatal interaction between these drugs and foods. |
Very important about MAO! | MAO inhibited in liver---build up of serum tyramine----triggers sudden release of norephineprine(potent vasoconstrictor)-----Hypertensive CRISIS:hypertension,tachycardia,doaphoresis,hyperpyrexia,cardiac arrythmias, tremulousness |
Foods that contain Tyramine to avoid while on MAOI's | aged cheese,aged meats:peperoni,summer sausage,all tap beers,overripe fruit,yogurt,peanuts, |
Wellbutron | can cause seizures 4x that of other antidepressants, contraindicated if seizure disorder as lowers seizure threshold |
