A 40 year old male patient is suffering from type II diabetes mellitus and hypertension. Which of the following antihypertensive drugs should not be used in such patients
## **Core Concept**
The question tests the understanding of antihypertensive drug classes and their implications in patients with type II diabetes mellitus. Type II diabetes mellitus is often associated with hypertension, and the choice of antihypertensive agent can significantly impact glycemic control and renal function.
## **Why the Correct Answer is Right**
The correct answer, , typically refers to a class of antihypertensive drugs that can worsen insulin resistance or have a negative impact on glucose metabolism. Beta-blockers, particularly non-selective ones, can mask symptoms of hypoglycemia and potentially worsen insulin resistance, although some newer beta-blockers have more favorable metabolic profiles.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option might represent ACE inhibitors or ARBs, which are generally considered beneficial or neutral in terms of glucose metabolism and are often recommended for patients with diabetes due to their protective effects on the kidneys.
- **Option B:** This could represent calcium channel blockers, which are also considered safe and effective in patients with diabetes, having a neutral effect on glucose and lipid metabolism.
- **Option D:** This might represent diuretics, specifically thiazide diuretics, which can have a negative effect on glucose tolerance but are not as directly implicated in worsening insulin resistance as some other classes.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that in patients with type II diabetes mellitus, ACE inhibitors and ARBs are preferred antihypertensive agents due to their renoprotective effects. Beta-blockers should be used cautiously, especially in patients with diabetes, as they can potentially worsen insulin resistance and mask hypoglycemic symptoms.
## **Correct Answer:** . Beta-blockers
