AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
RAYOS is a delayed-release oral tablet formulation of prednisone, a corticosteroid hormone receptor agonist approved by the FDA in July 2012. It is indicated for multiple conditions requiring corticosteroid therapy, with the delayed-release mechanism designed to optimize therapeutic delivery and tolerability. As a reformulated version of a legacy corticosteroid, RAYOS occupies a niche position in the broad corticosteroid market where it competes against both branded and generic prednisone products as well as alternative corticosteroid formulations.
