Final answer:
Glucocorticoids, such as cortisone and cortisol, are drugs that are thought to elevate blood glucose levels. They promote glycogen synthesis in the liver.
Step-by-step explanation:
Drugs that are thought to elevate blood glucose levels are called glucocorticoids. Glucocorticoids, such as cortisone and cortisol, increase blood glucose levels by promoting glycogen synthesis in the liver. Cortisol, for example, is released in response to stress and raises blood glucose levels at the expense of the metabolism of carbohydrates, fats, and proteins.
