This answer is incorrect.

The statement, "Levetiracetam is a drug for which the AAN recommends patients stick to one manufacturer's preparation, as evidence exists that there are differences between generic and brand name preparations." is false.
Levetiracetam works via an unknown mechanism, is indicated for treatment of partial seizures, is metabolized primarily by the kidney, is approved as adjunct therapy only, is excreted in breast milk, has no known significant drug interactions, and has no known significant interactions with other AEDs.  (See References)

B) Valproic acid is a drug for which the AAN recommends patients stick to one manufacturer's preparation, as evidence exists that there are differences between generic and brand name preparations.

This answer is incorrect.

The statement, "Valproic acid is a drug for which the AAN recommends patients stick to one manufacturer's preparation, as evidence exists that there are differences between generic and brand name preparations." is false.
Valproic acid causes reduction of sodium currents, causes increase of GABA-mediated currents, is indicated for treatement of complex partial seizures, is indicated for tonic-clonic, is indicated for treatment of absence seizures, is indicated for treatment of myoclonic seizures, is metabolized primarily in the liver, is a known teratogen, or evidence for its teratogenicity exists, is associated with an increased risk of spina bifida if taken during pregnancy, and is excreted in breast milk.  (See References)

C) Primidone is the drug of first choice for patients with absence seizures only.

This answer is incorrect.

The statement, "Primidone is the drug of first choice for patients with absence seizures only." is false.
Primidone causes reduction of sodium currents, causes increase of GABA-mediated currents, is a glutamate receptor antagonist, works via an unknown mechanism, is indicated for treatement of complex partial seizures, is indicated for treatment of partial seizures, is indicated for tonic-clonic, induces hepatic enzymes, is a known teratogen, or evidence for its teratogenicity exists, and is excreted in breast milk.  (See References)

This answer is incorrect.

The statement, "Oxcarbazepine is a drug for which the AAN recommends patients stick to one manufacturer's preparation, as evidence exists that there are differences between generic and brand name preparations." is false.
Oxcarbazepine causes reduction of sodium currents, is indicated for treatement of complex partial seizures, is indicated for treatment of partial seizures, is indicated for treatment of partial seizures with secondary generalization, is metabolized primarily in the liver, is approved as adjunct therapy only, induces hepatic enzymes, and is excreted in breast milk.  (See References)
