What are some examples of ACE inhibitors?

ACE inhibitors are a class of medications commonly used to treat conditions such as hypertension and heart failure by inhibiting the angiotensin-converting enzyme. This action leads to the relaxation of blood vessels and a decrease in blood pressure, making these medications effective in managing cardiovascular conditions.

The correct examples of ACE inhibitors include enalapril, ramipril, and lisinopril. These drugs specifically target the renin-angiotensin system to decrease the production of angiotensin II, a potent vasoconstrictor. Enalapril is often used for both hypertension and heart failure, ramipril has benefits in heart attack prevention, and lisinopril is commonly prescribed for its efficacy in improving outcomes in patients with heart failure.

The other options provided consist of various drug classes that do not include ACE inhibitors. Dopamine, dobutamine, and phenylephrine, for example, are primarily classified as inotropic agents or vasopressors used to support cardiac function or increase blood pressure in acute settings, but they do not have the same mechanism as ACE inhibitors. Hydralazine and nitroprusside are vasodilators but not ACE inhibitors, while milrinone is a phosphodiesterase inhibitor also used in
