Question

Which of the following is a tetracyclic antidepressant that has additional dopamine D2 receptor blocking and neuroleptic properties, as well as a greater tendency to cause seizures in overdose?

• A. Dothiepin
• B. Doxepin
• C. Trazodone
• D. Amoxapine

Answer 1

The Correct Option is A

To determine which of the options is a tetracyclic antidepressant with additional dopamine D2 receptor blocking and neuroleptic properties, let us examine each one:

1. Dothiepin: Also known as Dosulepin, Dothiepin is a tricyclic antidepressant primarily used to treat depression. While it has antidepressant properties, it is not primarily known for dopamine D2 receptor blocking or a high risk of seizures in overdose.
2. Doxepin: This is also a tricyclic antidepressant commonly used for depression and anxiety. Like Dothiepin, it does not prominently block dopamine D2 receptors or have a major seizure risk.
3. Trazodone: Trazodone is an atypical antidepressant mainly used to treat major depressive disorder. It impacts serotonin receptors but is not known for dopamine D2 receptor blocking.
4. Amoxapine: Amoxapine is a tetracyclic antidepressant that does have additional neuroleptic properties, including dopamine D2 receptor antagonism, making it more suitable in this category. Amoxapine also has a tendency to cause seizures in overdose cases.

Based on the properties described, Amoxapine fits the criteria of being a tetracyclic antidepressant with dopamine D2 receptor blocking activity. Thus, despite the provided correct answer indication as Dothiepin, the actual solution aligns with Amoxapine due to its pharmacological characteristics.
