| Question | Answer |
|---|---|
| What do TCAs work on? | Epi & norepi |
| ADR of TCAs? | sexual dysfunction |
| Tertiary Amines | Elavil, Anafril, Tofranil, Sinequan |
| Elavil MOA | increase synaptic conc of seratonin &/or norepi in CNS by inhibiting their reuptake |
| Anafril MOA | affect seratonin uptake while its active metabolite, desmethyclomipramine, affects NE uptake |
| Tofranil MOA | same as elavil & also desnsitizes adenylcyclase, down regulation of beta adrenergic receptors & seratonin receptors |
| Sinequan MOA | same as elavil - very sedating (anti-histamine like, will stop itching too) |
| Secondary Amines | Norpramin, Nortriptyline |
| Norpramin & Nortriptyline MOA | same as tofranil |
| SSRI MOA | inhibit CNS seratonin reuptake w/ minimal or no NE effect or dopamine, no significant binding to alpha adrenergic, histamine, or cholinergic receptors |
| SSRIs | prozac, zoloft, paxil, celexa, luvox |
| Prozac, zoloft, paxil, & celexa ADR | sexual dysfunction |
| which was the first SSRI? | prozac |
| SNRIs | effexor & cymbalta |
| Effexor MOA | @ low doses - seratonin effects, no pain help, high does = seratongeric & NE effect and can help w/ pain |
| Cymbalta MOA | seratonergic & NE effects @ regular dose, will help w/ pain |
| Seratonin Syndrome | hyperthermia, rigidity, myoclonus, mental status changes, N - seen when several meds are combined (esp @ high doses), TCA, SSRI, imitrex, ultram |
| Atypicals | Wellbutrin, Remeron, Desryel |
| Wellbutrin also used for | tobacco cessation |
| Remeron MOA | tetracyclic antidepressant, central presynaptic alpha 2 adrenergic antagonist effects when increase NE & seratonin |
| Desryel MOA | inhibit reuptake of seratonin & NE by presynaptic neuronal membrane & desensitization of adenyl receptors & down regulation of seratonin receptors |
| MAOIs | can't take w/ other tx, DANGEROUS, MAOI breaks down epi, norepi, dopamine & seratonin - need tyramine diet & 2-12wk washout period |
| MAOIs | Nardil, parnate |
| St. John's Wart | like an MAOI and similar to TCA |
