Pfizer, the manufacturer of Viagra, is among the big pharma players that has experienced setbacks and continued challenges. The latest announcement was a plunge of 18% in first-quarter profits for 2009.

The company’s Q1 2009 Earnings & Conference Call transcript will be available on April 29, 2009 at seekingalpha.com.

In terms of company stock, it was down 22 percent in 2008 and 12 percent in 2007. Pfizer shares sold at about $28 on June 1, 2007 and now (April, 2009) stand at less than $14.

Pfizer acquired Wyeth this year but forecasts for the manufacturer are not great despite substantial price increases for many of its products. Previous downsizing has occurred and will continue to occur due to the merger, and Lipitor’s patent will expire in 2011.
