What is the primary medical treatment for prolactinoma?

• A. Bromocriptine
• B. Cabergoline
• C. Octreotide
• D. Levodopa

Answer: (A)

The primary medical treatment for prolactinoma, a type of pituitary tumor that secretes excess prolactin, involves the use of dopamine agonists. Bromocriptine is one of these agents, specifically designed to reduce prolactin levels and promote shrinkage of the tumor. It works by stimulating dopamine receptors in the pituitary gland, which in turn inhibits the secretion of prolactin. Although cabergoline is also an effective dopamine agonist and is often preferred in clinical practice due to its more favorable dosing schedule and side effect profile, bromocriptine is traditionally recognized as the standard treatment for prolactinoma. This makes it a correct answer, particularly in contexts where historical or foundational knowledge is emphasized. Other treatment options like octreotide, primarily used for somatostatin-secreting tumors such as those found in acromegaly, and levodopa, which is used primarily in Parkinson's disease, are not suitable for managing prolactinomas, further supporting the relevance of bromocriptine in this scenario.
