- Lexapro (escitalopram)
SNRIs
- Effexor (venalafaxine)
- Pristiq (desvenlafaxine)
- Cymbalta (duloxetine)
Side Effects
- Emotional numbing
- Anorgasmia/sexual response
- Reduced “error detection” (anterior cingulate) governs over detection, drives consciousness, perfection and so on (give a damn level)

Tricyclics
- Tofranil (imipramine)
- Elavil (amitriptyline)
- Similar response rate as SSRIs, but lethal overdose potential
- Until 20 yrs ago most popular antidepressant; now less widely used
Atypical Antidepressants
- Wellbutrin (bupropion)
- Remeron (mirtazapine)
Wellbutrin works on dopamine/reward circuits - (spontaneous orgasm)
- only one that targets dopamine
- things more pleasurable
- potentially ups anxiety levels
- higher dosages can cause seizure and look like epilepsy
- below 300mg low dose
Remora hits dopamine and serotonin circuits - evidence of high response rate
- major weight gain
St. John’s Wart (hypericum)
- Largest U.S. study: St John’s = placebo, but both = Zoloft
- acts like and ssri in the brain
- but companies say: st. john’s wort: ineffective for MDD because didn’t beat placebo.
but Zoloft = GOOOOOD! (when not really)
