Methsuximide binds to T-type
calcium channels and
inhibits calcium influx. It
targets the alpha-1G subunit
specifically.
Hyperpolarization prevents
absence seizures
GABA release is inhibited
due to mutations of the
SCN1A, SCN1B gene causing
enhanced reuptake
Methsuximide is administered
as an oral capsule
