Calcium channel blockers

Calcium channel blockers are medicines used to lower blood pressure. They work by preventing calcium from entering the cells of the heart and arteries. Calcium causes the heart and arteries to contract (constrict) more forcefully. By blocking calcium, calcium channel blockers allow blood vessels to relax and open.

Calcium channel blockers can also slow the heart rate, which can lower blood pressure. These medications may also be prescribed to relieve chest pain (angina) and control an irregular heartbeat.

Calcium channel blockers are also called calcium antagonists.

Common side effects of calcium channel blockers include: constipation, dizziness, rapid heartbeat (palpitations), fatigue, flushing and hot flashes in the face and chest area, headache, and swelling in the feet and legs.

Grapefruit products should be avoided while taking some calcium channel blockers. Because grapefruit juice with medication and can affect heart rate and blood pressure. This can cause symptoms such as headache and dizziness.

What is Angina?

Angina is pain or discomfort (a feeling of pressure or squeezing) that occurs when the heart does not get enough oxygen (blood supply). Usually, a patient with angina feels pressure, pain, or soreness just below the chest bone, and sometimes pain can occur in the shoulder, arm, neck, jaw, or back. The symptoms of angina pectoris may be similar to the symptoms of indigestion.

Angina pectoris is not a disease, but rather a symptom of heart disease or ailment, and is usually the result of a disease in the coronary artery that supplies the heart with blood and oxygen (CAD). An angina attack occurs in coronary artery patients as a result of one or more of the following triggering factors:

  • Physical exertion, such as walking, climbing stairs, engaging in strenuous physical activity, or having sex.
  • Going out on a very hot or very cold day.
  • Eat a heavy meal.
  • Emotional stress or severe psychological crisis.
  • smoking.

Angina patients can be divided into two types:

Chronic stable angina pectoris: It results from a permanent and stable blockage in the coronary arteries feeding the heart muscle. It is also called stable angina pectoris or chronic stable angina pectoris.
Variable angina: It results from temporary narrowing, constriction or spasm of the coronary arteries supplying the heart. It is also called variable angina pectoris, Pranzimetl’s angina.

Why is Isoptin prescribed to patients with angina pectoris?

Cardiologists prescribe verapamil (the scientific name for Isoptin) for the prevention of chest pain caused by narrowing of the coronary arteries of the heart muscle (angina pectoris, also known as stable angina). Or in less frequent cases, such as chest pain resulting from severe contraction of the coronary arteries of the heart muscle (vasospastic angina, also known as Pranzimtel’s angina or variable angina).

If you suffer from angina pectoris (stable or variable), you should know that Isoptin improves the blood supply to the heart muscle, thus prevent chest pain (angina pain). It should be noted that verapamil does not relieve chest pain once it is used, but rather from continued use.

Isoptin is not prescribed to treat angina pain if it has already occurred, but it prevents its occurrence, therefore it is recommended to keep the doses of Isoptin that your doctor prescribed to you even if you feel well to avoid having an angina attack.

Isoptin is used as a first-line treatment in cases of coronary insufficiency, whether as a result of permanent obstruction (stable angina) or constriction of coronary arteries (Pranzimtel or variable angina) or both. Isoptin can also be used in cases of possible constriction of the coronary arteries. Isoptin may also be used alone or in combination with other anti-anginal medicines in patients who have not responded to nitrates and/or appropriate doses of beta-adrenergic blockers.

Isoptin is mainly used to treat myocardial ischemia when it is caused by a permanent blockage of the blood vessels in the myocardium, as in stable angina pectoris .

Isoptin can only be used as a stand-alone treatment or may be used in combination with other angina medications in patients who do not respond adequately to treatment with nitrates and/or beta-blockers.

What is supraventricular tachycardia?

Supraventricular tachycardia is a condition in which your heart suddenly beats much faster than usual. Supraventricular tachycardia is not usually serious, but some people may need treatment.

Supraventricular tachycardia occurs when the electrical system that controls your heart’s rhythm isn’t working properly.

This suddenly makes your heart beat faster. It can also slow down suddenly.

The normal resting heart rate is 60 to 100 beats per minute. But with supraventricular tachycardia, your heart rate suddenly rises above 100 beats per minute. This happened while resting or exercising.

Having supraventricular tachycardia means that your heart is suddenly beating faster. This tachycardia usually lasts a few minutes, but can sometimes last for several hours, and it can happen several times a day or once a year.

Supraventricular tachycardia can be caused by fatigue, caffeine, alcohol, or drugs — but there’s often no clear cause.

Supraventricular tachycardia can occur at any age, but most often it first begins in children and young adults – many people often have their first symptoms between 25 and 40 years of age.

People with supraventricular tachycardia may not have any other symptoms, but sometimes people may also feel:

  • pain in chest
  • Weakness, shortness of breath, or dizziness.
  • Unexplained fatigue.
  • Nausea , vomiting.

what is the high blood pressure?

High blood pressure, a medical condition known as (hypertension), it is also called (the silent killer). It is a condition mostly caused by narrowed arteries, which impede the easy flow of blood through the blood vessels. As a result, the heart is forced to pump blood more forcefully.

Over time, uncontrolled high blood pressure can damage arteries and other organs. This can lead to heart attack, heart failure, stroke, kidney disease, and other serious health consequences. High blood pressure is called the “silent killer,” because it has no symptoms. The only way to know if you have high blood pressure is to have your blood pressure checked by a doctor.

There is no cure for high blood pressure, however, there are several medications, including verapamil (Isoptin) that help control blood pressure. It’s important to note that eating a healthy diet, maintaining a healthy weight, not smoking, and being physically active can be just as important as taking medication. In most cases, cardiologists advise patients with high blood pressure to change their lifestyle.

Why Isoptin prescribed to patients with pressure?

If you suffer from high blood pressure, know that verapamil (the generic name for Isoptin) works by relaxing or widening the blood vessels, making blood pass through the blood vessels (arteries) easier.
