Summary of ANTIDEPRESSANTS Overview (SSRIs, MAOIs, TCAs) | Nursing Pharmacology | NurseInTheMaking
Summary of Video on Antidepressants
Main Ideas:
- Overview of antidepressants commonly tested in nursing school: SSRIs, TCAs, and MAOIs.
- Importance of understanding the risks associated with antidepressants, especially the increased risk of suicide when starting treatment.
- Need for gradual tapering of medications rather than abrupt cessation.
Key Concepts:
- General Risks of Antidepressants:
- All antidepressants may increase the risk of suicide, particularly when energy levels rise before mood improves.
- Patients should not stop taking these medications abruptly; a tapering schedule is necessary.
- SSRIs (Selective Serotonin Reuptake Inhibitors):
- Uses: Depression, anxiety, OCD, eating disorders.
- Mechanism: Inhibit serotonin reuptake, increasing serotonin levels in the brain.
- Suffixes to Remember: -talopram, -oxitine, -zodone (with sertraline as an outlier).
- Common Side Effects: Sexual dysfunction, gastrointestinal upset, weight gain, and serotonin syndrome (characterized by muscle rigidity, restlessness, high heart rate, and mental changes).
- Patient Education:
- Takes 4-6 weeks to see effects; compliance is crucial.
- Should be taken in the morning (memory trick: "take at sunrise").
- Avoid combining with MAOIs or St. John's Wort due to risk of serotonin syndrome.
- TCAs (Tricyclic Antidepressants):
- Uses: Depressive episodes, bipolar disorder, OCD, neuropathy.
- Mechanism: Block reuptake of serotonin and norepinephrine.
- Suffixes to Remember: -triptyline, -pramine (with amoxapine as an outlier).
- Common Side Effects: Dizziness, orthostatic hypotension, anticholinergic effects (urinary retention, blurred vision, dry mouth, constipation).
- Patient Education:
- MAOIs (Monoamine Oxidase Inhibitors):
- Uses: Depression.
- Mechanism: Inhibit monoamine oxidase, increasing epinephrine, norepinephrine, dopamine, and serotonin levels.
- Medications to Remember: Tranylcypromine, Isocarboxazid, Phenelzine (spelling out "TIP").
- Patient Education:
- Wait 14 days after stopping SSRIs or TCAs before starting MAOIs.
- Follow a tyramine-restricted diet to avoid hypertensive crises (high-tyramine foods include aged cheese, fermented meats, and overripe fruits).
- Should be taken in the morning to avoid sleep disturbances (memory trick: "MAOIs think morning").
- Takes 4 weeks to reach therapeutic effects.
Methodology/Instructions:
- Monitoring for Suicide Risk:
- Assess for suicidal thoughts, especially when a patient expresses increased energy.
- Patient Education:
- Educate patients about the time required for medications to take effect.
- Discuss dietary restrictions for MAOIs.
- Emphasize the importance of not stopping medications abruptly and the need for gradual tapering.
