**Core Concept**
Bulimia nervosa is a complex eating disorder characterized by recurrent episodes of binge eating followed by compensatory behaviors such as self-induced vomiting, laxative abuse, or excessive exercise. The treatment of bulimia nervosa requires a multidisciplinary approach, incorporating psychotherapy, nutrition counseling, and pharmacotherapy.

**Why the Correct Answer is Right**
The primary pharmacological treatment for bulimia nervosa is selective serotonin reuptake inhibitors (SSRIs), which have been shown to reduce the frequency and severity of binge eating and purging behaviors. SSRIs work by increasing the levels of serotonin in the brain, which helps to regulate appetite, mood, and impulse control. Fluoxetine, a specific SSRI, is the only medication that has received FDA approval for the treatment of bulimia nervosa.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because antidepressants other than SSRIs, such as tricyclic antidepressants, are not typically used to treat bulimia nervosa due to their side effects and lack of efficacy in this population.
**Option B:** This option is incorrect because antipsychotics are not a first-line treatment for bulimia nervosa and are typically reserved for patients with co-occurring psychotic symptoms.
**Option C:** This option is incorrect because mood stabilizers are not typically used to treat bulimia nervosa, as they are more commonly associated with the treatment of bipolar disorder.

**Clinical Pearl / High-Yield Fact**
It's essential to note that the treatment of bulimia nervosa should be individualized and may involve a combination of psychotherapy, nutrition counseling, and pharmacotherapy. Cognitive-behavioral therapy (CBT) is a commonly used form of psychotherapy for bulimia nervosa, as it helps patients identify and change negative thought patterns and behaviors.

**Correct Answer:** C.
