Tenormin and its Uses
Generic Tenormin belongs to a group of medicines called beta-blockers.
Beta-blockers reduce the workload on the heart and help it to beat more regularly. Generic Tenormin controls, but does not cure, high blood pressure (hypertension).
Generic Tenormin also relieves chest pain (angina), and can be helpful after a heart attack. Sometimes Tenormin is used to help prevent migraine headaches.
Generic Tenormin is often used in combination with other high blood pressure medications such as diuretics (water pills) when the use of one medication by itself is not enough to control blood pressure.

Tenormin Mechanism Tenormin Working
Generic Tenormin works by blocking beta receptors that are found in various parts of the body. Blocking beta receptors prevents the action of two chemicals, called noradrenaline and adrenaline, which are produced naturally by the body. These are often referred to as the 'fight or flight' chemicals, because they are responsible for the body's reaction to stressful situations.
Beta receptors are found in the heart. When they are blocked by Generic Tenormin the heart is made to beat more slowly and with less force. This reduces the pressure at which the blood is pumped out of the heart and around the body. This in turn reduces blood pressure, which means that Tenormin can be used to treat high blood pressure. It also reduces the energy used by the heart to pump blood around the body, and so reduces the heart's need for oxygen, which means it can also be used in the management of angina.
Angina is chest pain that occurs because the heart does not get enough oxygen to meet demand, such as when doing exercise. Generic Tenormin reduces the workload of the heart and so decreases its demand for oxygen. This helps to prevent attacks of angina.
Slowing the heart rate helps to control abnormal heart beats called arrhythmias. Arrhythmias can seriously undermine the pumping action of the heart and result in inefficient blood circulation around the body. Generic Tenormin corrects the abnormal heart beat and thus can be used to treat arrhythmias.
Generic Tenormin has also been shown to reduce the damage to the heart if taken in the period shortly following a heart attack. This decreases the likelihood of having a further heart attack and lowers the risk of continued illness and death.

Missed Dose of Tenormin
Take the missed dose of Tenormin as soon as you remember. However, if it is almost time for the next dose, skip the missed dose of Tenormin and take only the next regularly scheduled dose. Do not take a double dose of Tenormin.
Excess dose of Tenormin
Generic Tenormin in excess dose may show symptoms such as a slow heart beat, shortness of breath, fainting, dizziness, weakness, confusion, nausea, and vomiting.
Conditions with Tenormin
Store Tenormin at room temperature away from moisture and heat.

Food and Drug Interactions with Tenormin
- In people with diabetes, Generic Tenormin can prolong the lowering of blood sugar (hypoglycaemia) caused by insulin or other antidiabetic medicines. Individuals should monitor their blood sugar, as Tenormin can also mask the signs of hypoglycaemia.
- If Generic Tenormin is taken together with calcium channel blockers such as verapamil or diltiazem, the risk of slow heart rate, low blood pressure and heart failure may be increased. Tenormin should not be injected into a vein (intravenously) within 48 hours of discontinuing verapamil or diltiazem and vice versa.
- If Generic Tenormin is taken with nifedepine and possibly other calcium channel blockers, the risk of a severe fall in blood pressure and heart failure may be increased.
- If Tenormin medication is taken in combination with clonidine to lower blood pressure, there is a risk of a rebound increase in blood pressure if the clonidine is stopped. To avoid this, the Tenormin should be stopped several days before slowly stopping the clonidine.
- Non-steroidal anti-inflammatory drugs (NSAIDs) such as indomethacin may reduce the blood pressure lowering effects of Tenormin.
- Care should be taken when adrenaline is given with Tenormin medication as this combination can cause severe high blood pressure and slow heart rate.
- If Tenormin is taken with digoxin or anti-arrhythmic medicines such as disopyramide there may be an increased risk of slow heart rate.

Adverse effects with Tenormin
The adverse effects associated with Tenormin are
- Slower than normal heart beat (bradycardia)
- Dry mouth
- Changes in mood
- Disturbances of the gut such as diarrhoea, constipation, nausea, vomiting or abdominal pain
