Phenytoin primarily exerts its anticonvulsant effects by inhibiting voltage-gated sodium channels in neurons, thereby stabilizing neuronal membranes and reducing the likelihood of seizure generation.

Lamotrigine is often used as an adjunctive therapy in refractory epilepsy due to its broad-spectrum anticonvulsant activity and relatively favorable tolerability profile.

Valproate is primarily metabolized in the liver to form a glucuronide conjugate, which is then excreted in the urine.

Valproate is associated with the highest risk of hepatotoxicity among the commonly used antiepileptic drugs, particularly in children under the age of 2 years.

Ethosuximide is the drug of choice for the treatment of absence seizures due to its high efficacy and relatively low risk of adverse effects.

Valproate is associated with the highest risk of teratogenicity among the commonly used antiepileptic drugs, particularly in the first trimester of pregnancy.

Phenytoin is a broad-spectrum antiepileptic drug that is commonly used in the treatment of tonic-clonic seizures, as well as other types of generalized and partial seizures.

Phenytoin is associated with the highest risk of neurotoxicity among the commonly used antiepileptic drugs, particularly at high doses.

Valproate is commonly used in the treatment of myoclonic seizures due to its broad-spectrum anticonvulsant activity and relatively favorable tolerability profile.

Carbamazepine is associated with the highest risk of skin rash among the commonly used antiepileptic drugs, particularly in children.

Vigabatrin is commonly used in the treatment of infantile spasms due to its high efficacy and relatively low risk of adverse effects.

Valproate is associated with the highest risk of pancreatitis among the commonly used antiepileptic drugs, particularly in children under the age of 2 years.

Valproate is commonly used in the treatment of Lennox-Gastaut syndrome due to its broad-spectrum anticonvulsant activity and relatively favorable tolerability profile.

Carbamazepine is associated with the highest risk of blood dyscrasias among the commonly used antiepileptic drugs, particularly in children.

Stiripentol is commonly used in the treatment of Dravet syndrome due to its high efficacy in reducing seizure frequency and severity.
