  • Types of Antidepressant
    • Selective Serotonin Reuptake Inhibitors (SSRIs)
      • These block the reuptake (absorption) of serotonin.
        • This means it is free to be absorbed by other neurons for longer.
          • Therefore serotonin levels increase
      • Most commonly prescribed
    • Serotonin and Noradrenaline Reuptake Inhibitors (SNRIs)
      • Block the reuptake of noradrenaline and serotonins, leading to increased effects of both, then increased mood.
    • Monoamine Oxidase Inhibitors (MAOIs)
      • prevents the enzyme monoamine oxidase from breaking serotonin and noradrenaline down properly
        • more of the neurotransmitters are made available which lifts mood
    • Trycylics (TCAs)
      • prevent the reabsorption of serotonin and noradrenaline
        • they have longer to act and therefore the mood enhancing effect lasts longer
