Common complaints linked to these agents include nausea, diarrhea, insomnia, headache, agitation, and anxiety. Based on available data, it is not possible to determine whether or not the elderly are more sensitive than younger populations to these more frequent side effects.2 It should also be noted that SSRIs are metabolized in the liver and inhibit the drug metabolizing enzyme cytochrome

P-450, particularly isoenzyme CYP2D6,but others as well. The difference among SSRIs in this respect is probably of Inhibitors,research,lifescience,medical limited importance despite their heterogeneous metabolism. But this discussion is beyond the scope of this paper. It is widely acknowledged that a serotonin syndrome (excitation tremor, Inhibitors,research,lifescience,medical pyrexia) or a potentially fatal drug-drug interaction may occur if SSRIs are combined with MAOIs or L-tryptophan, or other drugs that might raise serotonin levels. Under its Evidence-Based Practice Program to guide clinical practice, the AHCPR reviewed newer antidepressants. With regard to older adults, and consistent with the above, dropouts overall and due to adverse effects do not differ significantly Inhibitors,research,lifescience,medical between older and newer antidepressants.46 In mixed-aged adults (data from older adults not being available), subjects discontinued treatment at similar rates for newer and older antidepressants due to lack of efficacy, adverse effects, or other reasons. However, about 4% fewer patients taking SSRIs discontinued

treatment due to adverse effects compared with patients taking TCAs. Compared with TCAs, SSRIs had higher rate differences (7% to 10%) of diarrhea, nausea, Inhibitors,research,lifescience,medical and insomnia, and a slight increase in headaches. TCAs had higher rate differences of dry mouth (30%), constipation (12%), dizziness (11%), blurred vision, and tremors (4%). Of particular concern in the elderly, several uncommon (<1%), but serious, adverse effects

were associated with the SSRIs, including bradycardia, bleeding, granulocytopenia, Inhibitors,research,lifescience,medical seizures, hyponatremia, hepatotoxicity, serotonin syndrome, extrapyramidal effects, and mania. Psychosocial therapy Psychosocial treatments have an essential role in the treatment of late-life Montelukast Sodium depression because of the broad range of functional and social consequences of depression in the elderly. Antidepressant treatments or electroconvulsive therapy (ECT) alone do not resolve many of the problems associated with geriatric depression, including lack of social support, medical illnesses, and Abiraterone solubility dmso significant and continuing adverse life events. Further, some patients strongly prefer nonbiologic interventions, while others are not suitable candidates for biologic interventions because of side effects, concomitant illnesses, or other circumstances. There are at least 8 randomized controlled trials indicating that psychosocial interventions are efficacious in treating major depression in the elderly (Table IV).
