Analysts were looking for earnings of 37 cents per share, according to consensus figures compiled by Thompson Financial/First Call. But the company's performance was within its previously predicted range of 35 cents to 37 cents per share. Second-quarter revenue grew to $3.2 billion, an increase of 6% from a year ago. Sales of human pharmaceuticals, the company's largest division, grew 8% to $2.5 billion in the second quarter.
