Effects of Acute Administration of Trazodone and Amitriptyline on Cognition, Cardiovascular Function, and Salivation in the Normal Geriatric Subject

Abstract
Trazodone, unlike amitriptyline, produced no impairment of psychomotor function or memory in normal geriatric subjects. Moreover, trazodone produced few cardiovascular effects. While drowsiness and a reduction in salivary flow were observed with trazodone, both are probably related to an α-blocking mechanism of action. Therefore, the unique pharmacological profile of trazodone offers a significant safety advantage over the tricyclic antidepressants in the geriatric patient.
