Description
Phenacemide 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.
Indication
Used to control certain seizures in the treatment of epilepsy.
Pharmacology
Phenacemide 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. Phenacemide 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.
Toxicity
Oral, mouse: LD50 = 987 mg/kg; Oral, rabbit: LD50 = 2500 mg/kg; Oral, rat: LD50 = 1600 mg/kg
Affected Organisms
Humans and other mammals
Biotransformation
Metabolized in the liver by hepatic microsomal enzymes, where it is inactivated by p-hydroxylation.
Absorption
Almost completely absorbed.
Half Life
22-25 hours.
