Fenostenyl - General Information

Fenostenyl is used to control certain seizures in the treatment of epilepsy. This medicine acts on the central nervous system (CNS) to reduce the number and severity of seizures.


Pharmacology of Fenostenyl

Fenostenyl is a ureal anticonvulsant indicated for control of severe epilepsy, particularly mixed forms of complex partial (psychomotor or temporal lobe) seizures, refractory to other anticonvulsants. Fenostenyl elevates the threshold for minimal electroshock convulsions and abolishes the tonic phase of maximal electroshock seizures. It also prevents or modifies seizures induced by pentylenetetrazol or other convulsants.
