"We continued to see growth in our front-end business, and with Easter falling on April 8 this year we anticipate that much of our Easter sales will be reflected in our April results," said Walgreens Executive Vice President and CFO Wade Miquelon.

Prescriptions processed by Express Scripts comprised 12.6 percent of Walgreens prescriptions in March 2011.

March pharmacy sales decreased 8.4 percent, while comparable store pharmacy sales decreased 11.1 percent. Calendar day shifts negatively impacted pharmacy sales in comparable stores by 2.1 percentage points. Comparable store pharmacy sales also were negatively impacted by 2.5 percentage points due to generic drug introductions in the last 12 months, by 0.9 percentage point due to lower incidence of cough, cold and flu and by 10.6 percentage points due to no longer being part of the Express Scripts network. Pharmacy sales accounted for 63.5 percent of total sales for the month.
