Which medication works by increasing insulin sensitivity in peripheral tissues, facilitating glucose uptake by cells, and is commonly used in the treatment of type 2 diabetes mellitus?
Metformin.
Glipizide.
Insulin lispro.
Exenatide.
The Correct Answer is A
Metformin is a commonly used oral antidiabetic medication that improves insulin sensitivity in peripheral tissues, reduces hepatic glucose production, and enhances glucose uptake by cells.
Incorrect choices:
b. This choice is incorrect. Glipizide is a sulfonylurea medication that stimulates insulin secretion from the pancreas, rather than increasing insulin sensitivity.
c. This choice is incorrect. Insulin lispro is a rapid-acting insulin analog used for mealtime coverage in insulin therapy.
d. This choice is incorrect. Exenatide is a glucagon-like peptide-1 (GLP-1) receptor agonist that stimulates insulin secretion and suppresses glucagon release, but it does not primarily target insulin sensitivity.
