Tenormin

What is it?

Composition

Tenormin contains the active substance atenolol, which is a representative of the group of selective beta-blockers. It provides a targeted effect on the cardiovascular system, reducing the load on the heart and blood pressure. In addition to the active component, the drug contains excipients that help maintain the stability of the drug and make it easy to use.

• Active substance: atenolol.
• Additional components: corn starch, lactose, povidone, magnesium stearate, hypromellose.
• Tablet shell: may contain titanium dioxide and macrogol to ensure strength and uniform dissolution.

Thanks to the combination of active and excipients, Tenormin is characterized by high bioavailability and long-term action. However, the presence of some components, such as lactose, may be important for patients with individual intolerance, so you should consult a doctor before use.

How to use?

Tenormin is intended for oral administration and its use requires strict adherence to doctors recommendations. Usually the drug is taken once a day at the same time to maintain a stable level of the active substance in the body. The tablet is washed down with a sufficient amount of water, regardless of food intake.

1. The standard starting dose is 50 mg per day. If necessary, the doctor may increase the dosage to 100 mg per day.
2. For patients with arterial hypertension, the minimum dose is often sufficient, while with angina or arrhythmia, a higher dose may be required.
3. In case of renal failure, the dosage is selected individually to avoid accumulation of the drug in the body.

It is important to remember that you cannot suddenly stop taking Tenormin, as this may cause an increase in symptoms, such as increased heart rate or increased blood pressure. If it is necessary to stop treatment, this should be done under the supervision of a doctor with a gradual reduction in the dose.

How does it work?

Tenormin acts due to the active substance atenolol, which belongs to the class of selective beta-blockers. This means that the drug specifically blocks beta-1-adrenergic receptors, located mainly in the heart. This mechanism helps reduce the load on the heart muscle and normalize the functioning of the cardiovascular system.

Atenolol reduces the frequency and strength of heart contractions, thereby reducing blood pressure and the volume of work of the heart. This is especially important in conditions such as angina, where the heart experiences oxygen deficiency. In addition, a decrease in heart rate helps prevent arrhythmia and reduces the risk of recurrent myocardial infarction.

Long-term use of Tenormin helps stabilize blood pressure and prevent sudden jumps. The drug acts gently, without affecting the respiratory system, which makes it safer for patients with mild asthma or chronic obstructive pulmonary disease.

Indications

Tenormin is used to treat various cardiovascular diseases. Its effectiveness is due to its targeted action on the heart and blood vessels, which makes the drug one of the key tools in the fight against hypertension and heart rhythm disorders. The drug is prescribed for long-term use, especially in situations requiring constant monitoring of the cardiovascular system.

• Arterial hypertension – to reduce and stabilize high blood pressure.
• Angina pectoris – to reduce the frequency and severity of chest pain attacks associated with a lack of oxygen in the heart muscle.
• Arrhythmia – to normalize the heart rhythm with tachycardia or extrasystole.
• Prevention of recurrent myocardial infarction – to reduce the risk of complications after a heart attack.
• Hyperkinetic cardiac syndrome – to reduce symptoms associated with increased activity of the cardiac system.

The appointment of Tenormin always requires taking into account the individual characteristics of the patient, including concomitant diseases and current medication regimens.

Contraindications

Tenormin is not suitable for use in a number of cases, as its action can worsen the condition or cause adverse reactions. Before starting treatment, it is important to ensure that there are no factors that make the use of the drug unsafe. The main contraindications are related to the specific effects of atenolol on the cardiovascular and other body systems.

• Bradycardia is a decrease in heart rate below normal.
• Cardiogenic shock is a critical condition in which the heart is unable to provide sufficient blood flow.
• Acute heart failure is the inability of the heart to pump blood effectively.
• Sick sinus syndrome is a malfunction of the natural pacemaker of the heart.
• Atrioventricular block grades II and III are serious disturbances in the conduction of electrical impulses in the heart.
• Severe forms of bronchial asthma or COPD are a risk of increased bronchospasm.
• Hypersensitivity to atenolol or any of the excipients of the drug.
• Metabolic acidosis is a violation of the acid-base balance in the body.

The drug should also be used with caution in liver and kidney diseases or diabetes. During pregnancy and breastfeeding, the use of Tenormin is allowed only under strict doctors instructions.

Side effects

Like any medicine, Tenormin can cause side effects, although not all patients experience them. Most often, they are associated with its effect on the cardiovascular system and the central nervous system. Most side effects go away on their own with continued treatment or after dose adjustment, but some of them require a visit to the doctor.

• Cardiovascular system: slow heart rate (bradycardia), decreased blood pressure, cold extremities.
• Central nervous system: fatigue, dizziness, drowsiness, in rare cases – depression or sleep disorders.
• Digestive system: nausea, diarrhea or constipation, dry mouth is possible.
• Respiratory system: in patients with bronchial asthma or COPD, bronchospasm may increase.
• Skin: skin reactions such as itching, rash, in rare cases – urticaria.

If you notice any side effects, especially those that get worse or cause discomfort, you should consult your doctor. In case of serious reactions, such as a sharp decrease in heart rate, severe dizziness or worsening breathing, you should immediately seek medical help.
