• Who might benefit from SNRIs?

  Those for whom SSRIs are not effective.
• What are the main classes of antidepressants mentioned in the study material?

  • SSRIs (Selective Serotonin Reuptake Inhibitors)
  • Tricyclics
  • SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors)
• What are the mechanisms of action for SSRIs, tricyclics, and SNRIs?

  • SSRIs: Prevent reabsorption and breakdown of serotonin.
  • Tricyclics: Block reabsorption of serotonin and noradrenaline.
  • SNRIs: Increase levels of serotonin and noradrenaline.
