Positive outcomes. Positive patient stories. At Paratek, we pursue solutions that enable positive outcomes and lead to positive patient stories. Paratek Pharmaceuticals is a biopharmaceutical company that develops transformative solutions for patients, both in and out of the hospital, with diseases that are difficult to treat. We focus on drugs that target infectious disease and other difficult to treat conditions. Four core elements serve as the foundation upon which our brand is built. They guide how we communicate, how we act and the experiences we create for our stakeholders.
