Generalized tonic-clonic seizures also are known as grand mal or major motor seizures. The study to evaluate the drug in primary generalized tonic-clonic seizures was a 12-week randomized double-blind placebo-controlled phase 3 study that evaluated 2 doses of pregabalin in 219 patients aged 5 to 65 years with primary generalized tonic-clonic seizures. Levetiracetam and perampanel are indicated as adjunctive therapy for these seizures.

Primary generalized tonic-clonic seizures respond to valproic acid topiramate or lamotrigine. To assess efficacy and safety of adjunctive perampanel in patients with drug-resistant primary generalized tonic-clonic PGTC seizures in idiopathic generalized epilepsy IGE. Clonic is the second stage when the muscles begin to jerk rapidly.

Primary generalized seizures arise simultaneously in both cerebral hemispheres. What are the types of generalized seizures. NCT01118949 comprising 12 weeks historical baseline 4 weeks prospective baseline 3 weeks titration target.
