Abstract

• SSRIs are the first-line therapy choice for most depressive disorders, although psychiatrists are increasingly prescribing SNRIs. Do patients consult PCPs or psychiatrists for help with their depressive disorders? What agents do physicians prefer? What role do reimbursement considerations play in prescribing habits?
• With dozens of antidepressants on the market, including a number of generic agents, it is becoming increasingly difficult for manufacturers of these agents to distinguish their products. What strategies have antidepressant manufacturers used to position their products? How well have these strategies succeeded? What strategies can be used to distinguish emerging agents?
• Branded antidepressants consistently have some of the highest promotional budgets among all pharmaceuticals. What is the correlation between promotional spend and drug sales? How does directto- consumer (DTC) advertising affect the uptake of a drug?

• Overview of antidepressants: tricyclics, monoamine oxidase inhibitors, SSRIs, SNRIs, dopaminergic/noradrenergic agents.
• Prescribing habits of physicians: treatment algorithms for major depression and bipolar disorder, physicians' choices of agents.
• Market for antidepressants: 2007 sales, generic erosion patterns for antidepressants, role of managed care in the market.
• Marketing strategies for antidepressants: Zoloft, Lexapro, Cymbalta, Pristiq, agomelatine. Market outlook: the value of promotional spend, the value of DTC advertising, marketing strategies for emerging agents.
