Everything you need to know about beta blockers

Beta-blockers are a group of drugs that have long been used in medicine to treat various diseases. Their action is based on blocking beta-adrenergic receptors, which affects many processes in the body. In this article, we will discuss how beta-blockers work, in what cases they are used, possible side effects and contraindications, and what important information is worth keeping in mind when using them.

Action of beta-blockers and indications for their use

Beta-blockers work by blocking beta-adrenergic receptors, which are responsible for transmitting nerve impulses to the heart and blood vessels. As a result, the heart beats slower and with less force, which leads to lower blood pressure and a reduction in the heart muscle’s demand for oxygen. Therefore, beta blockers are used in various situations:

• In the treatment of hypertension – they reduce blood pressure, which reduces the risk of cardiovascular complications.
• In the treatment of heart diseases such as arrhythmias, coronary artery disease and heart failure – they improve heart function, reduce the risk of heart attack and other complications.
• In migraine prevention – they can reduce the frequency and severity of migraine attacks.
• In the treatment of cardiac neuroses – they help control symptoms such as tachycardia and tremor.

Side effects and contraindications

Although beta-blockers are an effective drug, they can also cause some side effects and have their contraindications. Therefore, it is worth consulting a doctor before starting therapy. The most common side effects of beta blockers are:

• Slow heart rate – may lead to feeling tired and weak.
• Sleep problems and nightmares.
• Cold hands and feet.
• Stomach problems such as nausea and heartburn.

Contraindications to the use of beta-blockers include: asthma and other bronchopulmonary diseases, bradycardia (low heart rate), heart failure in the decompensation stage and some kidney and liver diseases.

What is worth remembering when using beta-blockers?

If you are a patient who uses beta blockers, there are a few important things to keep in mind:

• Check your blood pressure and pulse regularly under the supervision of a doctor.
