CNS Stimulants Drugs Pharmacology Quiz Questions
Question 1 of 5
Which of the following drugs, is an insulin sensitizer:
Correct Answer: B
Rationale: Rosiglitazone (choice B), a thiazolidinedione, enhances insulin sensitivity by activating PPAR-γ receptors, improving glucose uptake in muscle and fat, ideal for type 2 diabetes. Chlorpropamide (choice A), Glipizide (choice C), and Glyburide (choice D), sulfonylureas, stimulate insulin secretion, not sensitivity. Rosiglitazone's sensitizing action contrasts with secretagogues, addressing insulin resistance without hypoglycemia risk. This mechanism is critical for patients with metabolic syndrome, though its use is limited by side effects like fluid retention, requiring careful patient selection.

Question 4 of 5
A 27-year-old woman with amenorrhea, infertility, and galactorrhea was treated with a drug that successfully restored ovulation and menstruation. Before being given the drug, the woman was carefully questioned about previous mental health problems, which she did not have. The drug used to treat this patient was probably:
Correct Answer: A
Rationale: Bromocriptine (choice A), a dopamine agonist, treats hyperprolactinemia (causing amenorrhea, infertility, galactorrhea) by inhibiting prolactin, restoring ovulation. Mental health screening avoids psychosis risk. Desmopressin (choice B), HGH (choice C), and Octreotide (choice D) target different conditions. Bromocriptine fits the scenario.
Question 5 of 5
