• Autoimmune and Rare Diseases Business
    of Mallinckrodt Pharmaceuticals

    Mallinckrodt is pleased to bring Questcor and its entire business into our company, including its main product, H.P. Acthar® Gel (repository corticotropin injection), a naturally-derived formulation of adrenocorticotropic hormones used in a variety of disorders having an inflammatory component.

    The former Questcor is now known as the Autoimmune and Rare Diseases business within Mallinckrodt’s Specialty Brands segment. We will continue their focus on the treatment of patients with serious, difficult-to-treat autoimmune and inflammatory disorders, primarily in the fields of neurology, nephrology, rheumatology and pulmonology. All are areas of medicine which have significant unmet medical needs.

  • H.P. Acthar® Gel is now part of the Mallinckrodt Pharmaceuticals portfolio of products. Please click here for Full Prescribing Information for H.P. Acthar Gel. To learn more about Acthar and it's FDA-approved therapeutic indications, visit www.acthar.com.
