Methods of medical treatment with sur1-trpm4 channel inhibitors

Abstract

A method of treating or preventing adverse outcomes associated with tissue plasminogen activator (tPA) administration, cerebral edema-related side effects, cerebral edema associated with radiation therapy, or migraine headaches by administering an effective amount of a SUR1-TRPM4 channel inhibitor, such as glyburide, and optionally the co-administration of a second therapeutically active agent, to a subject in need thereof. Adverse outcomes associated with tPA include cerebral hemorrhage, cerebral edema, physical impairment or death. The administration of the SUR1-TRPM4 channel inhibitors occurs prior to the radiation therapy, during the radiation therapy, after the radiation therapy, or combinations thereof. The SUR1-TRPM4 channel inhibitor is administered prior to surgical excision of a brain tumor, CAR-T therapy, or administration of flutarabine. Alternatively, or in addition, the SUR1-TRPM4 channel inhibitor is administered prior the onset of the cerebral edema-related side effects.
