<p><b>New page</b></p><div>[[Angiotensin-converting enzyme]] inhibitors (ACE inhibitors) represent a class of medications primarily utilized in the treatment of [[hypertension]], but also find application in the management of heart-related conditions, diabetes, kidney diseases, and stroke. ACE inhibitors function by blocking the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, hence leading to blood vessel dilation and a reduction in blood pressure.<br />

=== Pharmacology ===<br />
<br />
Angiotensin-converting enzyme is a key component of the [[renin-angiotensin system]] (RAS), a critical regulatory system for blood pressure and fluid balance. ACE inhibitors effectively block the conversion of angiotensin I to the potent vasoconstrictor angiotensin II, thereby reducing vascular resistance and blood pressure. They also decrease angiotensin II-mediated aldosterone secretion, which reduces sodium and water reabsorption, contributing further to blood pressure reduction.<br />
<br />
=== Therapeutic Uses ===<br />
<br />
While primarily indicated for the treatment of hypertension, ACE inhibitors are also employed in managing various other medical conditions:<br />
<br />
* '''Heart Conditions:''' ACE inhibitors are useful in treating [[heart failure]], [[myocardial infarction]], and left ventricular dysfunction, as they help reduce cardiac workload and improve cardiac output.<br />
* '''[[Kidney disease]]:''' They offer renal protective effects, particularly in patients with [[diabetes]], by reducing intraglomerular pressure, thus slowing the progression of kidney disease.<br />
* '''[[Stroke prevention]]:''' These medications also play a role in secondary prevention of stroke, given their blood pressure-lowering effect.<br />
* '''[[Diabetes]]:''' ACE inhibitors have been found to delay the progression of diabetic nephropathy and mitigate cardiovascular risks in patients with diabetes.<br />
=== Side Effects and Contraindications ===<br />
<br />
As with any medication, ACE inhibitors are associated with potential side effects, such as dry cough, hyperkalemia, dizziness, and renal function alteration. Rare but severe side effects can include angioedema and neutropenia. Pregnant women or those planning to conceive should not use ACE inhibitors due to potential teratogenic effects.<br />
<br />
ACE inhibitors are contraindicated in patients with a history of angioedema related to previous ACE inhibitor therapy and those with bilateral renal artery stenosis.<br />
