What is the recommended treatment for depression in geriatric patients?

From the Guidelines

The most effective treatment for depression in geriatric patients is a combination of psychotherapy and medication, with selective serotonin reuptake inhibitors (SSRIs) being the first-line pharmacological option, as recommended by the most recent study 1. When treating depression in geriatric patients, it is essential to consider the risk of adverse effects, comorbidities, and the presence of behavioral and psychological symptoms associated with these mental health disorders.

• Non-pharmacological treatments such as exercise, psychotherapy, and behavioral interventions can help to alleviate depressive symptoms and improve mental health.
• Pharmacotherapy, particularly SSRIs, is effective and well-tolerated in older adults with dementia; however, antidepressants with an anticholinergic burden, such as tricyclics, should be avoided for older adults in general and especially for those with frailty and dementia. Some key points to consider when treating depression in geriatric patients include:
• Using medications with minimal anticholinergic side effects, such as sertraline, escitalopram, or citalopram, as they appear to be effective and have few side effects 1.
• Avoiding fluoxetine due to its long half-life and side-effects, and instead considering safer options such as venlafaxine, vortioxetine, or mirtazapine in terms of drug interactions 1.
• Implementing interventions targeting frailty, such as programs focused on physical activity, nutrition optimization, social engagement, and cognitive stimulation, which can improve physical function and quality of life, helping to reduce depressive symptoms 1. The treatment should be individualized and appropriate, considering the patient's specific needs and circumstances, and should continue for at least 6-12 months after symptom resolution, with some patients requiring maintenance therapy for years 1.

From the FDA Drug Label

Geriatric Use–U. S. geriatric clinical studies of Sertraline hydrochloride in major depressive disorder included 663 Sertraline hydrochloride -treated subjects ≥ 65 years of age, of those, 180 were ≥ 75 years of age No overall differences in the pattern of adverse reactions were observed in the geriatric clinical trial subjects relative to those reported in younger subjects No overall differences in the pattern of efficacy were observed in the geriatric clinical trial subjects relative to those reported in younger subjects.

The recommended treatment for depression in geriatric patients is Sertraline hydrochloride, as it has been studied in geriatric clinical trials with 663 subjects ≥ 65 years of age and showed no overall differences in the pattern of efficacy compared to younger subjects 2. However, it is essential to note that greater sensitivity of some older individuals cannot be ruled out, and SSRIS and SNRIs, including Sertraline hydrochloride, have been associated with cases of clinically significant hyponatremia in elderly patients. Key considerations for treatment include:

• Monitoring for adverse events, particularly urinary tract infection and hyponatremia
• Being mindful of the potential for greater sensitivity in older individuals
• Weighing the benefits and risks of treatment in this population.

From the Research

Treatment Options for Depression in Geriatric Patients

• The recommended treatment for depression in geriatric patients includes the use of selective serotonin reuptake inhibitors (SSRIs) such as sertraline 3, 4.
• Sertraline is generally well tolerated in elderly patients with major depressive disorder and lacks the marked anticholinergic effects that characterize the adverse event profiles of tricyclic antidepressants (TCAs) 4.
• The dose regimen for sertraline in the treatment of depression has been well established, with a starting dose of 50 mg/day, which is the usually effective therapeutic dose, and the optimal dose when considering both efficacy and tolerability for most patients 3.

Considerations for Geriatric Patients

• Elderly patients are particularly prone to the anticholinergic effects of TCAs, making SSRIs such as sertraline a better choice for the treatment of major depressive disorder in this age group 4.
• No dosage adjustments are warranted for elderly patients solely based on age, and sertraline has a low potential for drug interactions at the level of the cytochrome P450 enzyme system 4.
• Mirtazapine, a noradrenergic and specific serotonergic antidepressant (NaSSA), may be preferable to sertraline for certain elderly patients, particularly those with dementia, and can be cross-titrated with sertraline if required 5.

Management of Depression in Older Adults

• Depression in older adults is a common psychiatric disorder that can be effectively treated with antidepressants, psychotherapy, exercise therapy, and electroconvulsive therapy 6.
• Antidepressants may pose a greater risk for adverse events in older adults due to multiple medical comorbidities and drug-drug interactions in the case of polypharmacy, and high-quality evidence does not support the use of pharmacologic treatment of depression in patients with dementia 6.
• The use of SSRIs, such as sertraline, is recommended as a primary treatment for major depressive disorder in geriatric patients, due to their significant advantages over older drugs, especially tricyclic agents, in this age group 7.
