In which condition are ACE inhibitors typically used?

1. Diabetes

2. Hypertension

3. Asthma

4. Hypothyroidism

The correct answer is: Hypertension

ACE inhibitors, or angiotensin-converting enzyme inhibitors, are primarily utilized in the management of hypertension, which is high blood pressure. Their mechanism involves blocking the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. This leads to the dilation of blood vessels, thereby reducing blood pressure. Additionally, ACE inhibitors help to decrease the workload on the heart and can improve outcomes in patients with heart failure or those who have had a heart attack. While ACE inhibitors can have benefits for patients with diabetes, they are specifically indicated for hypertension to help reduce the risk of cardiovascular events and protect renal function. In conditions like asthma or hypothyroidism, ACE inhibitors do not have a primary role in treatment, as their mechanisms and effects do not address the underlying issues related to these diseases. This makes hypertension the primary condition for which these medications are typically prescribed.
