Pharmacology
Indication: For the control of absence (petit mal) seizures that are refractory to other drugs.
Pharmacology:
Used in the treatment of epilepsy. Methsuximide suppresses the paroxysmal three cycle per second spike and wave activity associated with lapses of consciousness which is common in absence (petit mal) seizures. The frequency of epileptiform attacks is reduced, apparently by depression of the motor cortex and elevation of the threshold of the central...

Mechanism of Action:
Binds to T-type voltage sensitive calcium channels. Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The i...

Half Life: 1.4-2.6 hours for mesuximide and 28-38 hours for the active metabolite.
Toxicity: Acute overdoses may produce nausea, vomiting, and CNS depression including coma with respiratory depression. Levels greater than 40 µg/mL have caused toxicity and coma has been seen at levels of 150 µg/mL.
Affected organisms: Humans and other mammals
Interactions
Food interaction:
Take with food
Avoid alcohol
Drug interaction:
TiclopidineTiclopidine may decrease the metabolism and clearance of Methsuximide. Consider alternate therapy or monitor for adverse/toxic effects of Methsuximide if Ticlopidine is initiated, discontinued or dose changed.
TriprolidineThe CNS depressants, Triprolidine and Methsuximide, may increase adverse/toxic effects due to additivity. Monitor for increased CNS depressant effects during concomitant therapy.
LamotrigineMethsuximide decreases the effect of lamotrigine
