METHSUXIMIDE Chemical Properties,Usage,Production
Description
Methsuximide is a succinimide that is converted to N-desmethylmethosuximide, a channel blocker that targets low threshold calcium currents. Methsuximide is a substrate of cytochrome P450 (CYP) isoform 2C19 that, in turn, inhibits CYP2C19-mediated metabolism of biguanides. Methsuximide has been shown to have anticonvulsant properties in clinical trials.
Chemical Properties
Light Yellow Oil
Originator
Celontin,Parke Davis,US,1957
Uses
A calcium channel succinimide antiepileptic drug. Anticonvulsant.
Definition
ChEBI: Methsuximide is an organic molecular entity.
Manufacturing Process
100 g of α-phenyl-α-methylsuccinic acid and 110 g of 40% aqueous methyl amine are heated together at 200 to 250°C until no more distillate is obtained. Upon vacuum distillation of the residue, the N-methyl-α-phenyl-αmethylsuccinimide, of BP 121° to 122°C at 0.1 mm is obtained. After recrystallization from aqueous ethanol, this compound melts at 52° to 53°C.
brand name
Celontin (Parke-Davis).
Therapeutic Function
Anticonvulsant
Clinical Use
Although methsuximide is less commonly used, it may be indicated for the control of absence seizures refractory to other drugs. Although it does not precipitate tonic-clonic convulsions, it often is combined with phenytoin or phenobarbital when absence seizures coexist with tonic-clonic symptoms. Much of the efficacy of methsuximide is attributed to its desmethyl metabolite. The half-life of methsuximide is between 2.6 and 4.0 hours, but the half-life for N-desmethylsuximide is 25 hours, causing it to accumulate substantially. Concentrations of greater than 40 g/mL may be associated with toxicity. Methsuximide is considered to be more toxic than ethosuximide.
