    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
    • Increase levels of these neurotransmitters in the brain
    • Can have various side effects due to affecting other neurotransmitters

    Tricyclic Antidepressant Uses

    • Anxiety
    • Chronic pain associated with nerves
    • Migraine pain relief
    • Panic attacks
    • Bipolar disorder
    • Obsessive-compulsive disorder

    Tricyclic Antidepressant Interactions

    • Sedatives (e.g., sleeping pills, alcohol): Increased drowsiness
    • Other mood medications : Dangerous reactions
    • Medications that dry out the body: Worse dry mouth, constipation
    • Heart medications: Higher risk of heart issues
    • Blood pressure medications: Reduced effectiveness in lowering blood pressure
    • Liver-affecting medications: Can increase or weaken the effects of TCAs

    Contraindications of Tricyclic Antidepressants

    • Age under 25 or over 65
    • Liver disease
    • History of seizures

    • Orthostatic hypotension (dizziness when changing positions)
    • Constipation
    • Weight gain

    Monoamine Oxidase Inhibitors (MAOIs)

    • Extremely potent antidepressants
    • Prevent the breakdown of serotonin, dopamine, and norepinephrine in the brain
    • This helps these neurotransmitters better regulate mood

    MAOIs Interactions

    • Antidepressants: Avoid combining
    • CNS stimulants: Increased blood pressure risk
    • Opioids: Risk of respiratory issues
    • Blood pressure medications: Unpredictable effects
    • Tyramine-rich foods: Risk of hypertensive crisis
    • Sedatives or alcohol: Excessive drowsiness or dangerous CNS depression

    Diet Restrictions for MAOIs Therapy

    • Avoid food containing tyramine
    • Cheese: High blood pressure risk
    • Smoked meats: High blood pressure risk
    • Soy sauce: High blood pressure risk
    • Cold remedies: Blood pressure risk
    • Diet pills: Blood pressure risk

    Side Effects

    • Trouble sleeping
    • Dizziness, lightheadedness, and fainting
    • Dry mouth, blurred vision, and appetite changes
    • Weight gain
    • Stomach issues
    • Headaches

    Selective Serotonin Reuptake Inhibitors (SSRIs)

    • A class of antidepressants commonly prescribed for mood disorders, anxiety, and related conditions
    • Increase serotonin levels in the brain, improving mood, anxiety, and overall mental well-being

    SSRIs Interactions

    • Carbamazepine-Decreased effectiveness of SSRIs
    • Cyproheptadine-Decreased effectiveness of SSRIs

    SSRIs Contraindications

    • Combining with MAOIs: Serotonin syndrome risk

    • Pregnancy (especially later stages)
    • Bipolar disorder
    • Hypersensitivity to the components

    SSRIs Side Effects

    • Insomnia
    • Headache
    • Weight loss

    Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)
