Widespread Generic Erosion of Atypical Antipsychotics Will Cause the Bipolar Disorder Drug Market to Decline By More Than $1 Billion Through 2018

Decision Resources, one of the world's
leading research and advisory firms for pharmaceutical and healthcare issues,
finds that widespread generic erosion of branded atypical antipsychotics will
cause the bipolar disorder drug market to decline from $6.3 billion in 2008 to
approximately $5 billion in 2018 in the United States, France, Germany, Italy,
Spain, the United Kingdom and Japan.

The new Pharmacor report entitled Bipolar Disorder finds that the market will
be constrained over the next several years by the patent expiries and
subsequent generic erosion of key antipsychotic agents such as AstraZeneca's
Seroquel, Eli Lilly's Zyprexa, Bristol-Myers Squibb/Otsuka's Abilify and
Pfizer's Geodon. In 2008, sales of atypical antipsychotics exceeded $4 billion
but generic competition, beginning in 2011, will cause sales of these agents
to decline to just under $3 billion by 2018, according to the report.
Additionally, patent expiries of branded antidepressants that include Wyeth's
(now Pfizer's) Effexor XR, Eli Lilly's Cymbalta/Xeristar and Forest/Lundbeck's
Lexapro/Cipralex will further constrain the market.
