[Hyponatremia: old age and antidepressants].

Area of Science:

• Geriatric Medicine
• Clinical Pharmacology
• Psychiatry

Background:

• Antidepressants are frequently prescribed for older adults.
• Selective serotonin reuptake inhibitors (SSRIs) are preferred due to their safety profile.
• Hyponatremia is a serious adverse effect associated with antidepressant use, particularly in the elderly.

Purpose of the Study:

• To investigate the incidence and clinical significance of hyponatremia in elderly patients using antidepressants.
• To analyze the clinical and psychiatric manifestations associated with antidepressant-induced hyponatremia in this population.

Main Methods:

• Literature review and analysis of existing studies on antidepressant use and hyponatremia in older adults.
• Examination of clinical case reports and epidemiological data.
• Synthesis of pharmacological and clinical information.

Main Results:

• Hyponatremia prevalence in elderly patients on antidepressants varies significantly (0.5% to 32%).
• Older adults are a particularly vulnerable group for developing hyponatremia.
• The condition is often underestimated or overlooked in clinical practice.

Conclusions:

• Hyponatremia is a relevant and potentially serious complication of antidepressant therapy in the elderly.
• Clinical awareness and systematic monitoring are crucial for early detection and management.
• Further research is needed to fully understand and mitigate the risks.
