Milestone Pharmaceuticals' CARDAMYST Nasal Spray Gains Express Scripts Formulary Access
Express Scripts has added Milestone Pharmaceuticals' CARDAMYST nasal spray to its national formularies, improving access to the first FDA-approved self-administered treatment for PSVT in 30 years. The drug was approved in December 2025 and clinical studies show it converts PSVT episodes twice as likely and three times faster than placebo. The company has also submitted a marketing application to European regulators.
