Preferred Antidepressant for an 84-Year-Old with Dyslipidemia and Recent Fall

Sertraline is the preferred antidepressant for this 84-year-old patient with dyslipidemia who is currently on escitalopram 15mg and has had a recent fall. 1

Current Situation Assessment

• The patient is currently on escitalopram (Cipralex/Lexapro) 15mg with "some benefit" for 4 years 1
• Recent fall is a significant concern as falls in older adults are associated with high rates of morbidity, mortality, and functional decline 1
• Dyslipidemia is a comorbid condition that requires consideration when selecting antidepressant therapy 1

Recommended Approach

First-line Recommendation:

• Switch to sertraline (50-200 mg/day) as it is:
  • Well-tolerated in elderly patients 1
  • Has less effect on metabolism of other medications compared to other SSRIs 1
  • Considered appropriate for older adults due to favorable adverse effect profile 1
  • Starting dose should be 50% of standard adult dose (25-50mg) 1

Rationale for Changing from Escitalopram:

• While escitalopram is generally well-tolerated in older adults, the recent fall suggests a need to reevaluate the current medication 1
• Falls in older adults with depression may be related to medication side effects, including SSRIs 1
• Sertraline has a more favorable side effect profile in terms of:
  • Less risk of QT prolongation compared to escitalopram
  • Less drug-drug interaction potential 1

Medications to Avoid in This Patient

• Paroxetine - associated with more anticholinergic effects that can increase fall risk 1
• Fluoxetine - has greater risk of agitation and overstimulation; not recommended in older adults 1
• Tricyclic antidepressants (especially tertiary-amine TCAs like amitriptyline) - associated with significant adverse anticholinergic effects and considered potentially inappropriate in older adults per Beers Criteria 1, 2
• Glyburide - should be avoided in older individuals due to greater risk of hypoglycemia 1

Implementation Plan

1. Gradual transition from escitalopram to sertraline:

   • Taper escitalopram over 10-14 days to limit withdrawal symptoms 1
   • Start sertraline at 25mg daily and titrate slowly based on response and tolerability 1

2. Fall risk mitigation:

   • Assess for orthostatic hypotension, which can be exacerbated by antidepressants 1
   • Consider referral for fall risk assessment 1

3. Monitoring plan:

   • Follow-up within 2-4 weeks after medication change to assess for side effects and efficacy 1
   • Monitor for drug-drug interactions, especially with medications for dyslipidemia 1

Duration of Treatment

• Since this patient has been on antidepressant therapy for 4 years, suggesting recurrent depression, continued treatment is likely beneficial 1
• After remission from recurrent depression, long-term maintenance treatment is recommended as the probability of recurrence increases with each episode (70% after two episodes, 90% after three episodes) 1

Special Considerations for Elderly Patients with Dyslipidemia

• Lower starting doses (approximately 50% of adult starting dose) are recommended due to greater risk of adverse drug reactions 1
• Consider the impact of antidepressants on lipid profiles - SSRIs generally have neutral effects on lipids 1
• Polypharmacy is a major concern in older adults with multiple conditions; medication review should be conducted regularly 1

By switching to sertraline, we aim to maintain antidepressant efficacy while potentially reducing the risk of falls and minimizing drug interactions in this elderly patient with dyslipidemia.
