title: Impact of formulary restrictions on the cost-effectiveness of antidepressant treatment.
abstract: Newer antidepressants are associated with higher costs of treatment of anxiety and depression. Managed care organizations are challenged to control treatment costs by implementing restricted formularies based on price and perceived medical value. Despite unfavorable side effects of efficacious tricyclic antidepressants, the low acquisition cost rationalizes the inclusion of this older class of agents on a formulary. On the other hand, cost-containment approaches have been taken toward more expensive drug classes (e.g., selective serotonin reuptake inhibitors) despite a superior safety profile of these drug classes over tricyclics. There is compelling evidence that dual reuptake inhibitors (e.g., venlafaxine extended-release), which have acquisition costs similar to serotonin reuptake inhibitors, have a broad spectrum of efficacy and thus added value, contributing to the cost-effectiveness of including this agent in the managed care formulary. Assessment of overall cost-effectiveness should not be limited by acquisition costs but should take total healthcare costs into consideration.
