AstraZeneca plc (NYSE:AZN) (LON:AZN) reported its second quarter earnings this morning, posting a 12 percent decline in profits because of competition from generic versions of some of its top sellers. The company’s sales fell by approximately $500 million because of the patent expirations. However, the decline during the second quarter was less than the 25 percent decline the drug maker attributed to generic drugs in the first quarter.

More of AstraZeneca’s patents expiring

The drug maker will continue to lose sales as more of its medications lose their patent protection. Crestor, the cholesterol control drug, and Seroquel, the antipsychotic medication, are both losing their patent protection. However, AstraZeneca plc (NYSE:AZN) (LON:AZN) is looking for ways to add more products. On Tuesday it announced that it would pay $815 million plus royalties to FibroGen Inc. for its experimental anemia therapy. In June the drug maker also announced it would acquire Pearl Therapeutics.

The drug maker’s Chief Executive Officer noted that patent expirations had a smaller effect on its profits in the second quarter, although the company still projects for sales to drop by a mid to high-single digit percentage if exchange rates are kept constant for the rest of this year. It expects core operating costs to increase to the low to mid-single digits.

AstraZeneca addresses legal problems

Last month staff members of AstraZeneca in China were interrogated by police. The drug maker said it is confident that the issue is an individual case and that it is sure that it has “the right processes in place to be compliant.”

The company is still cooperating with U.S. officials in connection with its practices in China and other markets while also conducting its own internal investigation.
