**Core Concept**
Hyperprolactinemia is a condition characterized by an elevated level of prolactin in the bloodstream, which can be caused by various factors including medications, pituitary tumors, and other endocrine disorders. Prolactin is a hormone produced by the pituitary gland that stimulates lactation and has a role in reproductive functions.

**Why the Correct Answer is Right**
The correct answer will involve identifying a medication or condition that does not cause hyperprolactinemia. This requires knowledge of the pathophysiology of prolactin regulation and the effects of different medications on the pituitary gland. The dopamine agonist bromocriptine, for example, is known to lower prolactin levels by stimulating dopamine receptors in the pituitary gland. In contrast, medications that block dopamine receptors, such as metoclopramide, can cause hyperprolactinemia.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because dopamine agonists, such as cabergoline, are known to cause hyperprolactinemia by stimulating dopamine receptors in the pituitary gland, which normally inhibit prolactin release.
**Option B:** This option is incorrect because antipsychotic medications, such as risperidone, can cause hyperprolactinemia by blocking dopamine receptors in the pituitary gland, leading to increased prolactin release.
**Option C:** This option is incorrect because antidepressant medications, such as selective serotonin reuptake inhibitors (SSRIs), can cause hyperprolactinemia by blocking serotonin receptors in the pituitary gland, which normally inhibit prolactin release.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that medications that block dopamine receptors can cause hyperprolactinemia, while dopamine agonists can lower prolactin levels. This knowledge can help clinicians identify and manage patients with hyperprolactinemia effectively.

**Correct Answer: D. Bromocriptine**
