Final answer:
Medications that do not lower blood pressure in normotensive patients are primarily used for treating diabetes.
Step-by-step explanation:
Medications that do not lower blood pressure in normotensive patients are primarily used for treating diabetes. These medications are not intended for controlling hypertension as they do not have an effect on blood pressure levels. Medications for blood pressure control, on the other hand, include classes such as thiazide-diuretics, calcium channel blockers, angiotensin converting enzyme inhibitors (ACE inhibitors), and angiotensin receptor blockers (ARBs).
