Therapeutic indications 

  • Control of hypertension( (or high blood pressure is a chronic medical condition in which the blood pressure in the arteries is higher than it should be. This requires the heart to work harder than normal to circulate blood through the blood vessels).
  • Management of angina pectoris( a medical term for chest pain or discomfort due to coronary heart disease. It occurs when the heart muscle doesn’t get as much blood as it needs. This usually happens because one or more of the heart’s arteries is narrowed or blocked, also called ischemia).
  • Control of cardiac dysrhythmias( a problem with the rate or rhythm of your heartbeat caused by changes in your heart’s normal sequence of electrical impulses. Your heart may beat too quickly, called tachycardia; too slowly, bradycardia; or with an irregular pattern)
  • Myocardial infarction for early intervention in the acute phase and long term prophylaxis after recovery ( Myocardial Infarction is the medical name for a heart attack. A heart attack is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage. This is usually the result of a blockage in one or more of the coronary arteries).

Dose and administration

  • Always take Blokium tablets exactly as your doctor has instructed you. You should check with your doctor or pharmacist if you are unsure. The general dose is for guidance only, and is as follows.
  • Generally, treatment is initiated at a low quantity, e.g. 25 mg. In accordance with the instructions of the doctor who is treating you, the dosage is then built up to the following quantities over the course of a few days. 
  • Elderly people: If you are an elderly person, your doctor may decide to give you a lower dose, particularly if you have problems with your kidneys.
  • People with severe kidney problems: If you have severe kidney problems your doctor may decide to give you a lower dose.

Hypertension Dosage: Most patients respond to 50 to 100 mg daily given orally in a single dose. The effect will be fully established after one to two weeks. A further reduction in blood pressure may be achieved by combining Blokium tablets with other antihypertensive agents. 

Angina Dosage: Most patients with angina pectoris will respond to 100 mg daily given orally as a single or divided dose. It is unlikely that additional benefit will be gained by increasing the dose. 

Certain types of chest pain (angina pectoris): The usual quantity for adults is 50 to 100 mg once a day (possibly split into 50 mg twice a day), or whatever quantity your doctor advises.  

Certain heart rhythm disorders (arrhythmias): The usual quantity for adults is 50 to 100 mg once a day, or whatever quantity your doctor advises. 

After a heart attack: Initial treatment will be by intravenous injection. After 15 minutes this will usually be followed by a 50mg dose of atenolol given orally (by mouth). 12hr after the intravenous dose, a further 50 mg oral dose will be given. A 100mg oral dose will be given after a further 12hrs. Treatment will then continue as a once daily 100mg dose.
