of exclusivity of Camptosar and Zyrtec/Zyrtec D, lower sales of Chantix following the changes to the product label, increased rebates partly as a result of the impact of certain contract changes, and increased pricing pressures. These factors were partially offset by the solid performance from certain legacy Pfizer products, including Lyrica, Viagra, Revatio, Xalatan and Sutent, and alliance revenues in 2009; and

• in our international markets, Biopharmaceutical revenues were flat in 2009, compared to 2008. Higher revenues due to the addition of legacy Wyeth products of $931 million, or 4%, and higher operational revenues from legacy Pfizer products of $783 million, or 3%, were offset by the unfavorable impact of foreign exchange on international revenues of $1.7 billion, or 7%. The increase in operational revenues of legacy Pfizer products was due to operational growth from Lipitor, Lyrica, Zyvox, Vfend, Sutent and alliance products, partially offset by lower revenues of Norvasc and Camptosar, among others.

During 2009, international Biopharmaceutical revenues represented 56% of total Biopharmaceutical revenues, compared to 57% in 2008.

Effective January 1, 2010, August 14, 2009, and January 3, 2009, we increased the published prices for certain U.S. Biopharmaceutical products. These price increases had no material effect on wholesaler inventory levels in comparison to the prior year.

2008 vs. 2007

Worldwide Biopharmaceutical revenues in 2008 were $44.2 billion, a decrease of 1% compared to 2007, primarily due to:

• a decrease in revenues for Zyrtec/Zyrtec D of $1.4 billion in 2008, primarily due to the loss of U.S. exclusivity and the cessation of selling this product in late January 2008 as a result of the 2006 divestiture of our former consumer healthcare business;

• a decrease in revenues for Norvasc of $757 million in 2008, primarily due to the loss of U.S. exclusivity in March 2007;

• an increase in rebates in 2008 due to a 2007 favorable adjustment recorded in 2007 based on the actual claims experienced under the Medicare Act, as well as the impact of our contracting strategies with both government and non-government entities in the U.S.;

• a decrease in revenues for Camptosar in the U.S. of $457 million in 2008, primarily due to the loss of U.S. exclusivity in February 2008;

• a decrease in revenues for Lipitor in the U.S. of $863 million in 2008, primarily resulting from competitive pressures from generics, among other factors; and

• an adjustment to the prior years’ liabilities for product returns of $217 million recorded in 2008,

partially offset by:

• an aggregate increase in revenues from products launched in the U.S. since 2006, particularly Sutent, and from many in-line products, including Lyrica, which increased 41% in 2008; and

• the weakening of the U.S. dollar relative to many foreign currencies, especially the euro, Japanese yen and Canadian dollar, which increased Biopharmaceutical revenues by approximately $1.5 billion, or 3.3%, in 2008.

Geographically,

• in the U.S., Biopharmaceutical revenues in 2008 decreased 13% compared to 2007, primarily due to the effect of the loss of exclusivity on Norvasc,
