Subtitle: Antihypertensives for Stroke Prevention
High blood pressure (hypertension) is a major risk factor for stroke. It is important to understand what types of antihypertensives are available and how they can help reduce the risk of stroke.
Antihypertensives are medications that are used to lower blood pressure. They work by reducing the amount of fluid in the body, decreasing the heart rate, and widening the blood vessels. These medications are prescribed by doctors to help reduce the risk of stroke or other cardiovascular diseases.
Angiotensin-converting enzyme (ACE) inhibitors are a type of antihypertensive that work by blocking an enzyme in the body that helps to produce angiotensin, a hormone that can cause the blood vessels to constrict. Examples of ACE inhibitors include captopril, lisinopril, and enalapril. These medications can help reduce the risks of stroke and other cardiovascular diseases.
Angiotensin II receptor blockers (ARBs) are another type of antihypertensive that block the action of angiotensin II, a hormone that causes the blood vessels to constrict. Examples of ARBs include losartan, valsartan, and telmisartan. These medications can help reduce the risk of stroke and other cardiovascular diseases.
Calcium channel blockers are a type of antihypertensive that work by blocking the calcium channels in the heart and blood vessels, helping to relax the blood vessels and reduce the risk of stroke. Examples of calcium channel blockers include amlodipine, nifedipine, and diltiazem.
Diuretics are a type of antihypertensive that work by increasing the amount of urine produced, which helps to reduce the amount of fluid in the body, resulting in lower blood pressure. Examples of diuretics include hydrochlorothiazide, furosemide, and spironolactone.
Beta blockers are a type of antihypertensive that work by blocking the beta receptors in the heart, helping to slow the heart rate and reduce the risk of stroke. Examples of beta blockers include propranolol, atenolol, and metoprolol.
The best type of antihypertensive for stroke prevention depends on the individual's medical history, risk factors, and other medications being taken. It is important to talk to your doctor about what type of antihypertensive is best for you.
