ANSWERS AND EXPLANATIONS

---

A) Lamotrigine is a known teratogen, or evidence for its teratogenicity exists.

This answer is incorrect.

The statement, "Lamotrigine is a known teratogen, or evidence for its teratogenicity exists." is false.
Lamotrigine causes reduction of sodium currents, causes increase of GABA-mediated currents, is a glutamate receptor antagonist, is indicated for treatment of partial seizures, is indicated for tonic-clonic, is indicated for treatment of atonic seizures, is indicated for treatment of tonic seizures, is indicated for treatment of myoclonic seizures, is indicated for treatment of Lennox-Gastaut syndrome, is metabolized primarily in the liver, and is excreted in breast milk.  (See References)

B) Ethosuximide causes reduction of sodium currents.

This answer is incorrect.

The statement, "Ethosuximide causes reduction of sodium currents." is false.
Ethosuximide causes reduction of T-Calcium currents, is indicated for treatment of absence seizures, is metabolized primarily in the liver, induces hepatic enzymes, has leukopenia as a relatively common side effect, has no known significant drug interactions, has no known significant interactions with other AEDs, and is the drug of first choice for patients with absence seizures only.  (See References)

C) Clonazepam 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, "Clonazepam 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.
Clonazepam causes reduction of sodium currents, causes increase of GABA-mediated currents, is indicated for treatment of absence seizures, is indicated for treatment of atypical absence seizures, is indicated for treatment of atonic seizures, is indicated for treatment of myoclonic seizures, is metabolized primarily in the liver, and is a known teratogen, or evidence for its teratogenicity exists.  (See References)

D) Primidone is approved as adjunct therapy only.

This answer is incorrect.

The statement, "Primidone is approved as adjunct therapy 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)

E) Lamotrigine is indicated for tonic-clonic.

This answer is correct.

The statement, "Lamotrigine is indicated for tonic-clonic." is true.
Lamotrigine causes reduction of sodium currents, causes increase of GABA-mediated currents, is a glutamate receptor antagonist, is indicated for treatment of partial seizures, is indicated for tonic-clonic, is indicated for treatment of atonic seizures, is indicated for treatment of tonic seizures, is indicated for treatment of myoclonic seizures, is indicated for treatment of Lennox-Gastaut syndrome, is metabolized primarily in the liver, and is excreted in breast milk.  (See References)
