Psychopharmacologic treatment of depression in the medically ill.

Appropriate selection of an antidepressant agent in medically ill patients requires a careful risk-benefit assessment matching the pharmacokinetic and pharmacodynamic properties of the drug being considered against the patient's physiological vulnerabilities, potential for drug interactions, and primary symptoms of the patient's depression. While in the past antidepressant drug selection was limited by the almost sole availability of the tricyclic antidepressants, newer drugs such as selective serotonin reuptake inhibitors, bupropion, and venlafaxine have vastly simplified treating depression in the medically ill. In refractory cases of depression in patients with medical illness, electroconvulsive therapy can be used with appropriate anesthetic management.
