What is the vasodilator?
vasodilators are a huge group of drugs and other substances that can help reduce blood pressure and be used to treat some symptoms of congestive heart failure. Usually they are not the treatment of the first line for people who simply suffer from high blood pressure because they can have numerous side effects. However, they are often prescribed in combination with other drugs to control various symptoms of cardiovascular disease.
Essentially, the vasodilator acts on the muscles surrounding the veins and/or arteries to relax, allowing to open or expand the blood vessels. This creates easier passage for running blood and can help reduce the workload of the heart. Some of these drugs only work on arteries and are called arterial dilators and others work on the smooth muscles of the surrounding veins and are called venous dilators. It is more common for a vasodilator to affect the veins and arteries and this type is called a mixed dilator.
These drugs are not only described by whether they work on veins, arteries nEbo both. Vasodilator is also classified according to how it acts to achieve its purpose. This is where the daunting is to try to understand many drugs that at least partially result in vasodilation, and it is also important to realize that many of these drugs are used for more than one purpose and perform more than one heart action. For example, nitrates are vasodilators, but can also help angina. Other types of drugs that cause some vasodilation include some diuretics, calcium channel blockers, ACE inhibitors, alpha-blockers and angiotensin II blockers.
Each of these drug classes will act in different ways. ACE inhibitors and angiotensin blockers change the way the body uses angiotensin II. The former blocks its production and the other prevents its mechanism to enter. Both types of drugs, affecting this body chemical, cause dilatation of blood vessels.
Doctors decide whether or what type of vasodilator is depending on manySuitable. These drugs are often used for life as soon as they are originally prescribed, although some are used for a short time. Vasodilator does not cure, but can help alleviate the symptoms of high blood pressure and congestive heart failure. Given the high diversity of drugs that fall into this class, all potential side effects could not be given. Some of the most likely side effects associated with these drugs are headaches, stomach sickness, chronic cough, dizziness and changes in the heart rhythm.
