Patient education over sexual dysfunction management must be handle carefully

Switching due to lack of efficacy after six weeks is appropriate and not an compliance issue

Abstract

Introduction

Novel pipeline drugs, lifecycle management of the current branded antidepressants, and development of atypical antipsychotics for depression are set to grow the depression market through to 2010 when it will peak at $14.6 billion. Thereafter, however, generic incursion of the atypical antipsychotics and the remaining branded antidepressants will see the depression market value drop to 2016.

Scope

This report focuses on the leading pharmacotherapies used to treat depression with sales and volume country- and indication-specific forecasts to 2016Assessment of current and future opportunities and threats in the depression market across the seven major pharmaceutical marketsFuture market events that are expected to affect drug revenues are discussed and quantified for each of the seven major marketsLifecycle management case studies show how previously successful strategies should be applied in today's market

Highlights

Sales of atypical antipsychotics in depression are set to be stimulated by anticipated positive clinical trial data investigating the use of Seroquel (quetiapine) in this indication. Datamonitor forecasts peak class level seven major market sales of $1.43 billion in 2008, followed by a decline due to competition from pipeline drugs and generics.Timing of launch of Wyeth's reformulation Pristiq (desvenlafaxine) would appear to be optimal. However, no evidence exists to indicate that it is an improvement over the parent compound Effexor (venlafaxine). By focusing Pristiq on a niche cohort of depressed patients, Wyeth has done enough to diversify Pristiq to ensure moderate success.The introduction of newer generation antidepressants such as the SNRIs Effexor and Cymbalta (duloxetine) and the SSRI Lexapro (escitalopram) into the Japanese depression market will drive its value considerably, resulting in a 52% increase by 2012.

Reasons to Purchase

Assess the impact of events such as patent expiries and new product launches on the depression-specific sales of key marketed brandsQuantify the future size of the depression market, in terms of volume and value, in each of the seven major marketsIdentify key lifecycle management strategies that can ensure growth in the competitive depression market
