Benefits of Inderal Tablet

In Prevention of Angina (heart-related chest pain)

Inderal 20mg Tablet relaxes the blood vessels so that blood can flow more easily around your body and makes sure that your heart is getting a good supply of oxygen. This makes it less likely that you will suffer chest pain caused by angina. This medicine can help increase your ability to exercise and go about your daily life more easily by reducing the frequency of angina attacks. You should take it regularly and as long as it is prescribed for it to work effectively.

In Treatment of Arrhythmia

Inderal 20mg Tablet is used to stabilize heart rate. It helps in normalizing an abnormal heart rhythm, preventing it occurring in the first place or slowing down the heart rate during an episode.

In Prevention of Heart attack

Inderal 20mg Tablet helps lower your blood pressure and make it easier for your heart to pump blood around your body. This reduces the chances of you having a heart attack. It can also reduce the risk of dying if it is given immediately after a heart attack. This medicine needs to be taken regularly to be effective, so keep taking it even if you feel well. Do not stop without talking to your doctor.

In Treatment of Hypertension (high blood pressure)

Inderal 20mg Tablet relaxes the blood vessels so that blood can flow more easily around your body. This lowers your blood pressure and reduces your risk of having a stroke, a heart attack, or kidney problems in the future. You do not usually feel any direct benefit from taking this medicine, but it works in the long term to keep you well. You should take it regularly as prescribed for this medicine to be most effective, even if you feel better.

In Treatment of Anxiety

Inderal 20mg Tablet stops your brain from releasing the chemicals that make you feel anxious so it can reduce the symptoms of excessive anxiety and worry. It can also reduce feelings of restlessness, tiredness, difficulty concentrating, feeling irritable and sleep problems that often come with Anxiety Disorder. Inderal 20mg Tablet will therefore help you go about your daily activities more easily and be more productive. Keep taking this medicine even if you feel well. Stopping suddenly can cause serious problems.

In Treatment of Tremors

Inderal 20mg Tablet helps improve the flow of blood and prevents abnormal activity of muscles that trigger tremors. This medicine can therefore enhance the quality of life by improving the ability to carry out daily functions in a better manner.

In Prevention of migraine

Inderal 20mg Tablet helps improve the flow of blood in your brain and prevents abnormal activity of muscles that triggers migraines. It is a very effective medicine for preventing migraine attacks, however, it does not treat an attack that has already started. By preventing and reducing the frequency of migraine attacks, the medicine can help you carry out your daily activities and improve your quality of life.

In Treatment of Pheochromocytoma

While carrying out surgery for the removal of pheochromocytoma, there is a risk of abnormally high blood pressure. Inderal 20mg Tablet blocks the effect of some chemicals on your heart and blood vessels. This slows down the heart rate and helps the heartbeat with less force thereby lowering your blood pressure. It is used for the immediate reduction of very high blood pressure (hypertensive emergency). Controlled blood pressure reduces the risk of having a heart attack, stroke, or kidney problems.

How Inderal Tablet works

Inderal 20mg Tablet contains Propranolol, a beta blocker. It works by affecting the body’s response to nerve impulses, especially in the heart. It slows down your heart rate and makes it easier for the heart to pump blood around the body. This prevents arrhythmias. It also widens the blood vessels in the body for better blood flow, thereby preventing angina as well as migraine. The exact mechanism by which it prevents tremors is not known, but experts believe that Inderal 20mg Tablet helps block the nerve impulses to the muscles responsible for tremors. Propranolol helps block the effects of the chemical messengers namely, adrenaline and noradrenaline, that are produced by the brain and are responsible for increasing your heart rate which makes you feel anxious. This way it helps with anxiety. While treating pheochromocytoma, Inderal 20mg Tablet may be given to block the action of high-adrenaline hormones, to lower the risk of developing dangerously high blood pressure during surgery for removing the tumor.
