All of the following are neuroleptic drugs except:
- A.
Lamotrigine
- B.
Thioxanthenes
- C.
Clozapine
- D.
Haloperidol.
Correct Answer
A. LamotrigineExplanation
Lamotrigine is not classified as a neuroleptic drug because it does not primarily act on dopamine receptors in the brain. Neuroleptic drugs, such as thioxanthenes, clozapine, and haloperidol, are commonly used to treat psychiatric disorders by blocking dopamine receptors. Lamotrigine, on the other hand, is an anticonvulsant medication primarily used to treat epilepsy and bipolar disorder by stabilizing neuronal membranes and inhibiting the release of glutamate. Therefore, lamotrigine does not belong to the neuroleptic drug class.Rate this question:

- A.
Carbamazepine
- B.
Lamotrigine
- C.
Ethosuximide
- D.
Depakene
Correct Answer(s)
C. Ethosuximide
D. DepakeneExplanation
Ethosuximide and Depakene are both known to block T-type calcium channels. T-type calcium channels are low voltage-activated calcium channels that play a role in regulating neuronal excitability. Blocking these channels can help reduce abnormal electrical activity in the brain, making them effective in the treatment of certain types of seizures. Carbamazepine and Lamotrigine, on the other hand, do not specifically target T-type calcium channels and have different mechanisms of action in the treatment of seizures.Rate this question:

- A.
Thalamus
- B.
Area of relay of thalamic neurons in the cortex
- C.
Basal ganglia
- D.
Brain stem
Correct Answer
B. Area of relay of thalamic neurons in the cortexExplanation
Ethusoximide exerts its anti-epileptic effect at the area of relay of thalamic neurons in the cortex. This means that the drug targets the specific region in the cortex where thalamic neurons relay information. By acting on this area, ethusoximide is able to regulate the transmission of signals and prevent abnormal electrical activity that leads to seizures. The drug's mechanism of action in this specific brain region helps to control and reduce epileptic episodes.Rate this question:

- A.
Tegretol
- B.
Depakene
- C.
Phenytoin
- D.
Lamotrigine
Correct Answer
B. DepakeneExplanation
Depakene is the correct answer because it is approved for first-line treatment of absence seizures when Ethusoximide is not available. Depakene, also known as valproic acid, is an anticonvulsant medication that is effective in controlling absence seizures. It works by increasing the levels of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain, which helps to reduce the occurrence of seizures. Tegretol, Phenytoin, and Lamotrigine are also anticonvulsant medications, but they are not specifically approved for the treatment of absence seizures when Ethusoximide is not available.Rate this question:

- A.
Valproate
- B.
Phenytoin
- C.
Carbamazepine
- D.
Lamotrigine
Correct Answer(s)
A. Valproate
C. CarbamazepineExplanation
Thrombocytopenia is a condition characterized by a low platelet count in the blood. Valproate and carbamazepine are both anticonvulsant medications that have been associated with thrombocytopenia as a potential side effect. These drugs can suppress the production of platelets in the bone marrow or cause immune-mediated destruction of platelets. Phenytoin and lamotrigine, on the other hand, are not commonly associated with thrombocytopenia. Therefore, the chronic use of valproate and carbamazepine can lead to thrombocytopenia.Rate this question:
