Betalox is a very common cardiac drug, which is also often used in clinical practice to treat coronary heart disease, and also has a certain therapeutic effect on chronic heart failure and cardiomyopathy.
Betalox is a β receptor blocker that exerts antiarrhythmic and myocardial oxygen consumption by inhibiting cardiac beta-1 receptor activity.
Long-term use of betalux can effectively improve the clinical symptoms of patients with coronary heart disease, and at the same time reduce the mortality rate of patients, but if betalux is taken for a long time, it will also bring some adverse reactions.
Let's take a look at the possible adverse reactions of long-term consumption of betalux.
1. Bradycardia
Bradycardia is the most common adverse effect of betalux, and there are two main reasons for this.
The first reason is that betalux can inhibit the contractile function of cardiomyocytes, causing patients to have bradycardia, and the second reason is that betalux can increase the excitability of sympathetic nerves.
In general, after taking betalux, the patient's heart rate will drop significantly, but if it is taken for a long time, it will cause the patient to develop bradycardia. When a patient develops bradycardia, it can also lead to an increase in myocardial oxygen consumption, which increases the risk of coronary heart disease and angina.
If bradycardia is caused by medications, you may want to change your medication or stop it. If bradycardia is caused by another medical condition, it can be improved by taking other medications. If the patient has a low heart rate, prompt symptomatic treatment is required.
2. Blood pressure drops
Betalox can inhibit the secretion of adrenaline and catecholamines, can effectively improve the function of the human myocardium, and can also inhibit sympathetic excitability, thereby reducing blood pressure. However, if you take betalux for a long time, it will cause the body's blood pressure to drop. Clinically, there are many elderly people who have a chronic disease called hypertension, and if the elderly have high blood pressure, they need to take betalux for long-term treatment.
If the blood pressure of the elderly does not drop after taking betalux, they need to continue taking it for a period of time. If the elderly take betalux for a long time, it will cause some adverse reactions in the body, and symptoms such as heart failure and arrhythmia may also occur.
3. Bronchospasm
Bronchospasm is a common adverse reaction in clinical practice, after taking betalux, patients will also have symptoms of bronchospasm, mainly due to the long-term use of betalux, the activity of β2 receptors in the human body will change, resulting in bronchial smooth muscle stimulation.
Patients may experience symptoms such as dry cough, chest tightness, and difficulty breathing after taking betalux, which can cause bronchospasm if not treated in time. Especially for some patients with asthma or chronic bronchitis, if you take betalux for a long time, it will also cause aggravation of the condition.
If symptoms of bronchospasm occur after the use of betalux, inhaled glucocorticoids and β blockers can be used reasonably under the guidance of a doctor. If the condition is not effectively controlled after taking the drug, it is necessary to seek medical attention in time to check whether you have bronchospasm.
4. Low blood pressure
Long-term use of betalux is likely to cause hypotension, mainly due to the fact that betalux belongs to a type of β blocker, which affects the endothelial cells of blood vessels, resulting in a decrease in vasodilation, which leads to a drop in blood pressure. And if there is a sudden drop in blood pressure while taking the drug, it is likely that there is some problem in the patient's body.
Therefore, when taking betalux, you must pay attention to not stopping the drug or reducing the dose suddenly, otherwise it is likely to cause the blood pressure to drop too quickly. If the drug is stopped or reduced suddenly, it is likely to cause low blood pressure and even fainting.
5. Dizziness and headache
After taking betalux, there will also be symptoms of dizziness and headache, this dizziness headache is generally caused by the adverse reaction of the drug, many patients will have a brief headache after taking the drug, mainly because the ingredients contained in the drug have a certain dilating effect on the blood vessels of the brain, thus causing cerebral congestion.
When the blood flow in the body slows down after taking the drug, the brain will experience dizziness and headache due to insufficient blood supply. If you take betalux for a long time, it will also have a certain effect on the brain, which will cause problems such as memory loss and mental decline. If the above symptoms appear, the patient should go to the hospital in time.
6. Edema
Long-term use of betalux can also lead to edema in the human body, especially in the lower limbs and facial areas. The mechanism of action of betalux is to enhance the heart function by inhibiting the cardiac β1 receptor, thereby reducing the oxygen consumption of the myocardium, which can play a role in the treatment of coronary heart disease and chronic heart failure.
If edema occurs after taking betalux, it is necessary to stop the drug in time, otherwise the condition will be aggravated. But there are also some things to be aware of in everyday life. When taking betalux, it is important to pay attention to the dosage of the drug not to be too large, otherwise it will increase the burden on the kidneys.
In addition, if you have uncomfortable symptoms such as cough, phlegm, and asthma after taking betalux, you must go to the hospital in time.
Reminder: Be cautious when taking medication, do not use drugs without authorization, and do not increase or decrease the dose at will without the guidance of a doctor
