A practice question
Choose an answer and it is marked, with the explanation. From USMLE Step 1 Practice Questions: 10 Worked Items.
A 32-year-old woman has amenorrhea, galactorrhea, and decreased libido. MRI shows a 9-mm pituitary microadenoma. Which medication most directly reduces the hormone driving her symptoms?
Cabergoline is a dopamine D2-receptor agonist. Dopamine released by the hypothalamus tonically inhibits prolactin secretion from lactotrophs, so a dopamine agonist lowers prolactin and often shrinks a prolactinoma. Octreotide suppresses growth hormone and is the strongest distractor because it is also used for a pituitary adenoma, but it does not directly treat hyperprolactinemia.
Yours are written from your own notes, and the free plan needs no payment details.
