Family Nurse Practitioner Exam

Which medication is indicated for the treatment of obsessive-compulsive disorder?

1. Paroxetine (Paxil CR)

2. Haldoperidol (Haldol)

3. Lorazepam (Xanax)

4. Imipramine (Elavil)

The correct answer is: Paroxetine (Paxil CR)

Paroxetine (Paxil CR) is indicated for the treatment of obsessive-compulsive disorder (OCD) as it belongs to the class of selective serotonin reuptake inhibitors (SSRIs). SSRIs are commonly used as a first-line treatment for OCD because they help increase the levels of serotonin in the brain, which can improve mood and reduce symptoms of anxiety associated with OCD. Paroxetine has been specifically studied and shown to be effective in reducing the obsessive thoughts and compulsive behaviors characteristic of this disorder. The favorable efficacy and safety profile make it a preferred option among clinicians treating patients with OCD. The other medications listed do not target OCD specifically: Haldoperidol is an antipsychotic that is typically used for schizophrenia and other psychotic disorders. Lorazepam is a benzodiazepine primarily used for anxiety and does not treat the underlying causes of OCD. Imipramine, while an antidepressant, is primarily used for depression and not a primary treatment for OCD. This distinction underlines the importance of utilizing medications that target the specific neurotransmitter pathways involved in OCD.
