November 3, 2022

Sumial or propranolol is a medicine widely used to treat symptoms of physiological anxiety like the tachycardias and tremors. It is also frequently used in cases of hypertension and cardiovascular problems in general.

We propose to analyze what Sumial is, what it is for and what are the possible side effects it can cause, especially if we use it irresponsibly.

What is propranolol?

"Sumial" is the commercial name of propranolol, a drug from the group of beta-blockers, which inhibit adrenaline and noradrenaline a and therefore the physiological stress response.

This means that propranolol decreases the activation of the sympathetic nervous system, which manifests itself in a reduction in heart rate that has relaxing effects at the physical and psychological levels.

Sumial and other beta-blockers are used mainly for "stage fright" and to treat heart and cardiovascular system problems, such as cardiac arrhythmias.

What is it for?

We have already mentioned the best known uses of propranolol, but has other therapeutic applications in addition to the reduction of heart rate and physical activation . Anyway, it must be taken into account that this product should only be consumed under medical indication and supervision.

1. Physical symptoms of anxiety

Sumial is effective in reducing symptoms of physiological arousal such as palpitations, tremors and excessive sweating or hyperhidrosis. All these can be presented as physical symptoms of anxiety, so in many cases they occur in stressful situations that our body interprets as threats.

This type of symptoms are more frequent in people with a tendency to anxiety of physiological type , as it may be in cases of social phobia or post-traumatic stress, although they can occur in anxiogenic situations without the need to comply with this condition.

However, although Sumial's regular use without a prescription is difficult, given difficult exams or speeches in public, this can be risky: since we can not be sure how our body will react to the medication, taking it in these cases could worsen the performance.

2. Hypertension and cardiac disorders

The main indication of the Sumial is the treatment of heart problems since it reduces the heart rate . In this way it is effective to treat hypertension, cardiac arrhythmia and angina pectoris, as well as to prevent heart attacks in people who have already suffered one.

Previously propranolol and beta blockers in general were widely used to treat hypertension, but these drugs have lost popularity because there are other more effective. Diuretic drugs such as thiazides stand out, because by making the blood vessels contain less fluid they cause a reduction in blood pressure.

3. Headache

Sumial is effective for the treatment of headaches, migraines and headaches, including cluster headache. In particular, it is considered to work well for the prevention of headaches.

Propranolol is especially indicated in the prevention and treatment of childhood migraines since there are few medications that combat them effectively and safely. Amitriptyline, riboflavin and some anticonvulsants can also be used for this purpose.

4. Capillary hemangioma

The hemangioma or "strawberry mark" is a type of benign tumor of the skin that appears in some babies during its first year of life. The striking red color of hemangiomas is due to the fact that they are formed by blood vessels.

Capillary hemangiomas usually disappear between 5 and 10 years without the need for treatment. If necessary, corticosteroids or beta-blockers are administered or a surgical operation is performed. to.

5. Hyperthyroidism

Sumial may also be effective in treating thyroid problems , which produce symptoms such as increased heart rate, diarrhea, weight loss and irritability, as well as others similar to those of anxiety.

This is important, given that the thyroid gland is a kind of directory of hormones. Problems in this organ are able to generate a chain reaction that affect several areas of the body, as well as affect mood.

6. Pheochromocytoma

Pheochromocytoma is a type of tumor of the adrenal gland caused by high blood pressure. The recommended treatment for this disease is a combination of propranolol and an alpha-adrenergic blocker .

7. Glaucoma

Glaucoma is an eye disease that is usually due to ocular hypertension . This disorder manifests itself in the progressive diminution of the visual field and if left untreated can cause significant damage to the optic nerve, as well as loss of vision.

8. Essential tremor

The concept "essential tremor" refers to a type of benign tremors that normally occur in the hands, usually begin after age 40 and worsen with age.

Essential tremor seems to have a genetic basis and is affected by factors such as physical exhaustion or stress . When they are severe enough to require treatment, beta-blockers are used as first-line medication.
