Final answer:
After a thiazide diuretic, an ACE inhibitor or an ARB is commonly started in a hypertensive patient with diabetes.
Step-by-step explanation:
After a thiazide diuretic, a medication that is commonly started in a hypertensive patient with diabetes is an angiotensin converting enzyme inhibitor (ACE inhibitor) or an angiotensin receptor blocker (ARB). These medications are especially recommended for patients with diabetes because they have been shown to have protective effects on the kidneys and can help reduce the risk of diabetic nephropathy.
