Abstract |
INTRODUCTION: Antidepressants (ADs) are widely used among elderly persons, making AD-related safety an important issue. Areas covered: This review highlights safety considerations related to AD use including risks associated with inappropriate and off-label use. The age-related pharmacokinetic and pharmacodynamic changes underlying safety concerns connected to ADs are outlined. Drug-drug interactions as a cause of AD-related adverse drug reactions (ADRs) are also discussed. We reviewed scientific evidence concerning three important safety outcomes related to ADs in elderly persons: cardiac arrhythmias, hyponatraemia and falls/fractures. Expert opinion: Several AD-related ADRs in elderly people are likely to be preventable. Current evidence suggests that selective serotonin re-uptake inhibitors (SSRIs) are best avoided particularly in persons with kidney disease due to the risk of hyponatraemia. The use of tricyclic antidepressants (TCAs) should be limited in the elderly due to anticholinergic adverse effects. TCAs should also be avoided in elderly persons at high risk of cardiovascular events due to a risk of cardiac arrhythmia. Emerging evidence suggests that SSRIs also have arrhythmogenic potential. Both TCAs and SSRIs should be used cautiously in elderly persons at risk of falls. Future research in this area should aim to investigate the lowest effective dose of AD possible, the relationship between AD dose and adverse effects, and which elderly subgroups are most prone to develop severe ADRs.
