We provide formulations of
ion channel modulators. [Solution] The present invention partially relates to compositions or dosage forms comprising condensed heteroaryl compounds useful for preventing and / or treating diseases or conditions associated with abnormal function of
voltage-gated
sodium ion channels, such as abnormal delayed / persistent
sodium currents. Methods for treating diseases or conditions associated with abnormal function of
sodium ion channels, including neurological disorders (e.g.,
Dravet syndrome,
epilepsy), pain, neuromuscular disorders, trigeminal-autonomic headache (TAC), migraines, cranial nerve disorders or polycranial nerve disorders, and cortical spreading depression (CSD), are also provided herein. In another aspect, the present invention provides methods for producing
ion channel modulators.
