OverviewWhat are blood pressure medications?Blood pressure medications (antihypertensives) are medicines that bring your blood pressure down in various ways. Some blood pressure medications make your blood vessels widen so blood gets through more easily. Others remove extra fluids from your blood or block natural hormones your body makes that raise blood pressure. Show
In addition to your age, race and gender/sex, your healthcare provider will consider your other health problems and how high your blood pressure is when deciding which high blood pressure medication to give you. Your treatment will be different from your neighbor’s or your brother’s prescriptions because each of you has a unique situation. You may need to take more than one type of high blood pressure medication to bring your blood pressure numbers down. Your healthcare provider may try one antihypertensive agent and add a second or third little by little to bring your blood pressure down. They may also start and stop antihypertensive drugs if they aren’t giving results or you develop intolerable side effects or unsafe changes in your bloodwork. Your healthcare provider will likely ask you to take your blood pressure at home each morning, before you have had any caffeine. Most people take blood pressure medications in the form of a pill you swallow every day, but your doctor may give you some antihypertensive medications through an IV (intravenous) in your arm during a hospital stay. What do blood pressure medications treat?Blood pressure medications treat high blood pressure, or hypertension, with the goal of keeping your heart strong and preventing heart failure, a heart attack, kidney failure or a stroke. High blood pressure makes your heart’s job more difficult and more demanding. Bringing your blood pressure down makes it easier for your heart to keep pumping blood to your essential organs and cells 24 hours a day. How common are antihypertensives?Antihypertensive drugs are very common, as an estimated 1 billion people in the world have high blood pressure. In the United States, about 50% of people aged 20 and older have high blood pressure and might take high blood pressure medication. What is the most popular medication for high blood pressure?Healthcare providers have several “first-line” or first-choice blood pressure medications they prescribe. They include:
Types of blood pressure medicationAdrenergic blockers (including alpha, beta, alpha-beta and peripherally acting blockers)What they do: They keep your body from raising its blood pressure in reaction to stress. Selected blood pressure medication side effects:
Angiotensin-converting enzyme (ACE) inhibitorsWhat they do: They keep your body from making angiotensin II (a blood vessel constrictor). Selected blood pressure medication side effects:
Angiotensin II receptor blockers (ARBs)What they do: They keep angiotensin II from making your blood vessels constrict. Selected blood pressure medication side effects:
Calcium channel blockers (including dihydropyridines and nondihydropyridines)What they do: They keep calcium out of your blood vessels, which lets the muscle in your blood vessels relax and loosen. Selected blood pressure medication side effects:
Centrally acting alpha-agonistsWhat they do: They prevent your nervous system from responding to stress. Selected blood pressure medication side effects:
Direct vasodilatorsWhat they do: They make your blood vessels more open. Selected blood pressure medication side effects:
Diuretics (including potassium-sparing, loop, thiazide and thiazide-type diuretics)What they do: They help your blood vessels get wider and make your kidneys move extra fluid and salt into your pee. Selected blood pressure medication side effects:
Risks / BenefitsWhat are the advantages of antihypertensives?Blood pressure medications help many people lower their high blood pressure and keep their hearts from becoming overworked. They also help people avoid having heart failure, kidney failure, a heart attack or stroke. What are the risks or complications of blood pressure medication?Some older adults have a sudden drop in blood pressure when they stand up (orthostatic hypotension). Antihypertensive medication can make this worse, and older adults can get dizzy and fall, sometimes getting injured. Some antihypertensive medications change your electrolyte levels as you lose extra fluid in your urine. Too high or too low levels of potassium can cause dangerous heart rhythms. Recovery and OutlookWhat is my outlook on blood pressure medication?Many people are successful in controlling their blood pressure with antihypertensive drugs. This helps prevent serious cardiovascular and kidney problems, in combination with a healthy diet and exercise. People who keep their blood pressure in a normal range keep taking their medicine at the same time every day without missing doses. They also keep going to regular checkups with periodic bloodwork to be sure the antihypertensive drugs aren’t causing any problems. It’s also important to follow a good lifestyle, including:
Why is my blood pressure still high on medication?There are a number of reasons why your blood pressure may still be high when you’re taking blood pressure medication. Reasons why it seems your high blood pressure medication isn’t working include:
When to Call the DoctorWhen should I see my healthcare provider?Tell your healthcare provider if you’re having problems with blood pressure medication side effects.

What is the first drug of choice for hypertension?First-line (first choice) options include these blood pressure medication names: Thiazide diuretics, calcium channel blockers and ― for people who have kidney disease and heart failure ― angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs). Beta-blockers may also be first-line choices if you have a history of heart disease. What is the best antihypertensive medication?The best antihypertensive medication is the one that works best for you and your specific situation. Everyone has different health problems. What works well for one person may not work well for another. You may need two or three different antihypertensive agents to bring your blood pressure into the normal range.

Which dietary choice is most appropriate and should be encouraged by the nurse for a client diagnosed with hypertension?The DASH diet is a healthy-eating plan designed to help treat or prevent high blood pressure (hypertension). The DASH diet includes foods that are rich in potassium, calcium and magnesium. These nutrients help control blood pressure. The diet limits foods that are high in sodium, saturated fat and added sugars.
Which agent would the nurse anticipate administering intravenously to lower a patient's severely elevated blood pressure?If the blood pressure remains elevated after beta blockade, a vasodilator such as intravenous nitroglycerin or nitroprusside may be administered. The drugs of choice in treating a hypertensive emergency with acute pulmonary edema are intravenous nitroglycerin, clevidipine, or nitroprusside (1,2,5).
When describing the adverse effects associated with ACE inhibitors which would the nurse include?The primary adverse effects of ACE inhibitors include hyperkalemia, dry cough, angioedema, hypotension, dizziness, headache, and renal insufficiency. [10][16] These effects may be more common in patients with renal, autoimmune, or collagen vascular diseases.
