Vasodilator drugs for headache

1 The spectrum of action of vasodilating

Drugs of this group are called vasodilating differently. The main task of the drugs is to restore the vascular function to normal and stabilize the brain activity by relaxing the walls of the artery or vein.

For this, drugs use the action of alpha and beta blockers of adrenergic receptors.

In addition, if a migraine is diagnosed, stimulation of imidazoline receptors should be carried out in parallel. In addition, at the same time, the level of calcium in the blood is restored, since it is the high level of calcium that leads to the development of a headache. In addition, medications affect cGMP cells by acting on vascular walls that are lined with a smooth muscle layer. So, it is briefly possible to tell about influence of a medicine on an organism of the person at occurrence of a headache. Depending on the narrow specialization of the constituent preparations, it is possible to single out:

• nitrates of organic origin, affecting the pain of venules;

• blockers and non-selective inhibitors that act on arterioles;
• have an effect on the entire vascular system.

Drugs can be divided into anti-spasmolytic drugs and drugs that lower blood pressure and dilate blood vessels. All medications for pain in the head can be combined in connection with their myotropic mechanism of action. However, it is very important to neutralize the headache in the body, the structure of nerve cells and blood vessels, sedative action and neurotropic action. The medicine is prescribed by the doctor not only for one-time treatment of pain in the head, but also for long-term therapy. For example, the doctor appoints a long-term tablets, when an arterial hypertension is diagnosed or chronic constriction in peripheral vessels is diagnosed. Below is a description of medicines that help to effectively cope with pain in the head.

2 Overview of medicines

Doctors usually prescribe the following vasodilators for treatment:

1. No-shp Tablets. The most popular tool. The tablets relieve spasm, they begin to act very quickly, after 10-15 minutes. And this is extremely important when there are severe pains.

4. Tablets: Eufillin. This medicine has an extended spectrum of action, it also helps with migraines. Tablets also dilate blood vessels, and relieve spasm, and lower blood pressure, and even relieve bronchospasm. To achieve a better effect, doctors usually inject injections of Eufillina intramuscularly instead of tablets. Sometimes add glucose. From these tablets can be observed side effect. Use with caution, as directed by your doctor.

Medicines with nicotinic acid. Assigned often, but can cause side effects - red spots on the face. With the correct dosage, this effect will be eliminated.

3 Tablets for antihypertensive and analgesic therapy

Drugs that dilate blood vessels can be divided into:

• beta-blockers;
• nitrates;
• inhibitors of ACE receptors.

B-adrenoblockers act on the peripheral receptors of the heart muscle. In addition, they reduce the number of heart beats per minute, thereby reducing cardiac output. Peripheral receptors are blocked, and, accordingly, oxygen consumption by myocardium decreases, blood pressure decreases. B-adrenoblockers give an antiarrhythmic effect, reduce the active effect on the body of renin. This group of medicines also has a cardioprotective effect. The blockers are divided into selective and non-selective. Most commonly, doctors prescribe the following drugs of this group:

• Nadolol;
• Propranolol;
• Pindolol;
• Oxprenolol;
• Bisoprolol;
• Betaxolol;
• Atenolol.

Usually, blockers are prescribed for migraines, myocardial infarction, heart failure, tachycardia, arterial hypertension, angina pectoris.

Drugs are prescribed only by a doctor, since they have side effects for pregnant women with diabetes. It is forbidden to take drugs of this group with patients with heart block, peripheral vascular diseases, and lung pathologies. The next group of drugs - nitrates, began to be used to treat hypertension, crisis, ischemic illness for a long time. Drugs of this group increase coronary current, because they dilate the vessels and remove spasms of the coronary arteries.

Nitrates are not allowed if there was a cerebral hemorrhage, or if the pressure inside the skull is increased. Vasoconstrictors are used to relieve spasms and eliminate migraine. In this case, it is good to use blockers that soothe the blood vessels. ACE inhibitors are used for the treatment of hypertension, infarction, left ventricular dysfunction. Do not use this group of drugs for people with stenosis of the renal arteries, with hyperkalemia and women during pregnancy. Vessel dilatation drugs are used in medicine and give a positive effect on the therapy of heart, vessel and head diseases. To apply this or that drug it is possible only under the reference of the doctor.
