Study Notes

Antidepressant Medications

  • Antidepressants treat depression and other mental health conditions like anxiety, OCD, and PTSD
  • They work by altering neurotransmitter levels (chemical messengers like serotonin, dopamine, and norepinephrine) in the brain, regulating mood, emotions, and behavior
  • Antidepressants are not a quick fix but often part of a comprehensive treatment plan including therapy and lifestyle changes

History of Antidepressants

  • Tricyclic Antidepressants (TCAs) and Monoamine Oxidase Inhibitors (MAOIs) were introduced in the 1950s
  • These early medications had significant side effects
  • The 1980s saw the introduction of Selective Serotonin Reuptake Inhibitors (SSRIs) like Fluoxetine (Prozac), offering fewer side effects and improved safety profiles
  • New classes of antidepressants, including SNRIs and Atypical Antidepressants, emerged in the 2000s, providing more treatment options

Classification of Antidepressants

  • Tricyclic Antidepressants (TCAs): Increase serotonin and norepinephrine levels
  • Monoamine Oxidase Inhibitors (MAOIs): Inhibit the breakdown of neurotransmitters
  • Selective Serotonin Reuptake Inhibitors (SSRIs): Increase serotonin's availability
  • Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): Increase serotonin and norepinephrine levels
  • Atypical Antidepressants: Mechanism of action varies depending on the specific drug, typically affecting serotonin, norepinephrine, or dopamine

Tricyclic Antidepressants (TCAs)

  • Ease depression by affecting chemical messengers in brain cells (neurotransmitters)
  • Block the reabsorption (reuptake) of serotonin and norepinephrine
