King's three key businesses are not only complementary to Pfizer's businesses, but are also strategically aligned with Pfizer's Primary Care, Established Products and Animal Health business units, enabling a seamless combination that will maximize King's assets with Pfizer's global organization's scale and resources. This strategic combination will allow Pfizer to leverage its existing commercial capabilities and expertise to create one of the leading broad portfolios for pain relief and management in the biopharmaceutical industry, offering both currently marketed opioid and non-opioid products, as well as a pipeline spanning stages of clinical development. In addition to Pfizer's current treatments for pain – which include Lyrica and Celebrex – King will bring Avinza, the Flector Patch and the recently launched Embeda, the first approved opioid pain product with design features intended to discourage misuse and abuse, two compounds in registration, which have the potential to lower the risk of abuse, as well as other compounds in development.
