**Question:** Drug of choice for panic disorders is -
A. Buspirone
B. Fluoxetine
C. Clonazepam
D. Alprazolam
**Core Concept:**
Panic disorders are a type of anxiety disorder characterized by sudden and recurrent episodes of intense fear or anxiety, often accompanied by physical symptoms such as palpitations, sweating, and trembling. Treatment options for panic disorders typically involve pharmacotherapy and psychotherapy.
**Why the Correct Answer is Right:**
The correct answer, Buspirone (A), is an azaspirodiazepine compound that acts as a partial 5-HT1A receptor agonist. It increases GABAergic neurotransmission in the central nervous system, leading to a reduction in anxiety symptoms. Buspirone is generally well-tolerated, with fewer side effects compared to other anxiolytics like benzodiazepines or selective serotonin reuptake inhibitors (SSRIs).
**Why Each Wrong Option is Incorrect:**
**Option B (Fluoxetine):**
Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) primarily used for treating depression and obsessive-compulsive disorder (OCD). While it can improve anxiety symptoms and panic disorder-related symptoms, it is not the first-choice medication for panic disorders due to its slower onset of action and potential side effects.
**Option C (Clonazepam):**
Clonazepam is a benzodiazepine commonly used for treating anxiety disorders. It acts as a GABA agonist, increasing the inhibitory neurotransmission of GABA in the central nervous system. While clonazepam is effective in reducing anxiety symptoms, it carries the risk of dependence, tolerance, and withdrawal symptoms upon discontinuation. Additionally, it is not specifically tailored for panic disorders and can be associated with sedation and cognitive impairment.
**Option D (Alprazolam):**
Alprazolam is another benzodiazepine that acts as a potent GABA agonist, increasing the inhibitory neurotransmission of GABA in the central nervous system. Similar to clonazepam, alprazolam is effective in reducing anxiety symptoms but carries risks of dependence, tolerance, and withdrawal symptoms upon discontinuation. Additionally, it is not specifically tailored for panic disorders and can be associated with sedation and cognitive impairment.
**Core Concept:**
Pharmacotherapy for panic disorders often involves selective serotonin reuptake inhibitors (SSRIs) or benzodiazepines. Buspirone is a suitable choice due to its slower onset of action and fewer side effects compared to benzodiazepines.
**Why Each Wrong Option is Incorrect:**
**Option B (Fluoxetine):**
Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) commonly used for treating depression and obsessive-compulsive disorder (OCD). While it can be effective in reducing anxiety symptoms, it is associated with a slower onset of action compared to benzodiazepines, making it less suitable for acute management of panic attacks.
