BACKGROUND: The choice of antidepressants for initial pharmacological treatment of depression in older adults and associated patients' characteristics are understudied. We aimed to describe the first selected antidepressant (first-choice) for depression in older adults (≥65 years) and whether patients' sociodemographic and clinical characteristics influence selecting an alternative first-choice (any other antidepressant than the nationally recommended first-choice sertraline) in Denmark.
METHODS: Register-based cross-sectional study including all older adults who redeemed their first antidepressant prescription for depression at community pharmacies in Denmark in 2015-2019. We analyzed the effect of patients' characteristics on the first-choice antidepressant selection using multinomial logistic regression.
RESULTS: Among 34,337 older adults with a first antidepressant-prescription, over two-thirds filled alternative first-choice antidepressants than sertraline (28.9 %): escitalopram or citalopram (30.3 %) or mirtazapine (34.4 %). Socially disadvantaged older adults (e.g., with short educational attainment, being single, or of non-western ethnicity) and clinically vulnerable older adults (e.g., having somatic diagnoses and hospital contacts) were more likely to use alternative first-choice antidepressants.
LIMITATIONS: Information on prescribers and in-hospital medications was not included in this study.
CONCLUSIONS: Further investigation of the first antidepressant selection and its impact on depression treatment outcomes in older adults is necessary. Moreover, for older patients, national guidelines on depression treatment should be more specific.
ARTICLE SUMMARY: Antidepressant selection for initial pharmacological treatment of depression in older adults can be difficult due to comorbidity, polypharmacy, and age-related changes in pharmacokinetics and pharmacodynamics. Real-world evidence/knowledge on first-choice antidepressant selection and associated user characteristics are rare. This Danish register-based cross-sectional study found over two-thirds of older adults filled alternative antidepressants (primarily escitalopram/citalopram or mirtazapine) than nationally recommended first-choice sertraline for depression treatment and identified wide-ranging sociodemographic and clinical factors influencing the first antidepressant selection.
