Which of the following drugs are not used in the treatment of hypertension?

Options

A. vasodilators
B. diuretics
C. vasoconstrictors
D. reserpine

Answer

To determine which drugs are not used in the treatment of hypertension, we need to understand the types of medications typically prescribed for managing high blood pressure.

### Step-by-Step Solution:

1. **Understanding Hypertension**:
- Hypertension, or high blood pressure, is a condition where the blood pressure in the arteries is persistently elevated. Normal blood pressure is around 120/80 mmHg, while hypertension can be 140/90 mmHg or higher.

2. **Types of Drugs Used in Hypertension**:
- **Vasodilators**: These drugs help to widen blood vessels, which lowers blood pressure. They are commonly used in the treatment of hypertension.
- **Diuretics**: These medications help the body eliminate excess sodium and water, reducing blood volume and lowering blood pressure. They are also commonly used in hypertension management.
- **Beta-blockers**: These drugs reduce heart rate and the force of contraction of the heart, which can lower blood pressure.

3. **Identifying Non-Treatment Drugs**:
- **Vasoconstrictors**: These drugs cause blood vessels to narrow, which raises blood pressure. Since hypertension is characterized by high blood pressure, vasoconstrictors are not used to treat this condition. Instead, they would exacerbate the problem.

4. **Conclusion**:
- Among the options provided, the drug that is not used in the treatment of hypertension is the vasoconstrictor.

### Final Answer:
- The drug that is not used in the treatment of hypertension is **vasoconstrictor**.
