This section contains further information about the Therapy Areas in which our efforts are focused:

• Cardiovascular

We describe the business environment, trends and other factors that have influenced our decision to focus on diseases in these six areas, our strategic objectives for each and our progress towards achieving these objectives. We include information about our marketed medicines and how they are designed to make a meaningful difference for patients, together with an overview of performance during the year. We also report in detail on the potential new products and product life-cycle developments in our pipeline that reflect our commitment to maintaining a flow of innovation that adds value for our shareholders and to society.

For a list of all our potential new products and product life-cycle developments see the Pipeline by Therapy Area at 27 January 2011 table and the Development Pipeline table. For details of patent expiries of our key marketed products, see the Patent expiries section.
