What are antihypertensive medicines?
Antihypertensives are medicines that help reduce abnormally high blood pressure or hypertension. Sometimes they are also called blood pressure medicines and can be used to treat more than one symptom of cardiovascular disease. Typically, these drugs are divided into a number of sub -groups that are defined by the way they act to reduce blood pressure. The type of the most recommended antihypertensive will vary from patient to patient and is a good topic of conversation between patients and their doctors.
Antihypertensive groups may include medicines called alpha and beta-blockers, angiotensin or ACE, calcium channel blockers, vasodilators and diuretics. Several other classes are angiotensin receptor blockers, central agonists and sympathetic nerves inhibitors. Several drugs may belong to the same class and each class is defined by its action.
alpha and beta-blockers look different from each other. Beta-blockers that are commonly prescribed to reduce heart rate to heartE worked less, and it can reduce blood flow to the heart and out of the heart, causing blood pressure to fall. Alfa-blockers focus on arteries and how rigid or durable they can be. Blood reduces the stiffness smoothly and blood pressure can be reduced. Antihypertensive drugs sometimes include both Alfa and Beta-blocker that uses this combined action. Carvedilol is an example of combined alpha and beta-blocker.
Somewhat similar to beta-blockers are vasodilators that also cause blood vessels to relax. Medicins falling in this class include minoxidil, which can be better known for its attributes as the current medicine for hair loss. Central agonists represent another solution and reduce blood vessels. Other antihypertensive drugs do not focus on blood vessels, but instead affect how the body repositses liquids. Diuretics accelerates the process of removing fluids from the body in the form of urine and mIt can reduce blood pressure by reducing the volume of fluid.
Some antihypertensive drugs prevent certain effects of the body. Calcium channel blockers prevent calcium migration to heart cells, and this reduces the heart rhythm. Blood vessels also relax when these drugs are used. ACE inhibitors reduce the production of angiotensin of the body, resulting in blood vessels narrowing and a higher risk of hypertension. On the other hand, angiotensin receptor blockers prevent angiotensin from binding to certain cells, causing less blood vessels to reduce.
There is a possibility that many of these drugs could be combined and the right choice for each person depends on different health conditions, especially on other heart conditions. Another point of view is the tolerance of the patient with antihypertensive treatment and can be said that people will have different effects that are individually based and depend on the type of drug used. It is best to discuss with a physician expected types of side effects with each groupFor medicines and warning signals that the drug may not work properly or causes undesirable reaction.
