Seloken ZOK works by blocking the action of a chemical called noradrenaline, which is released from nerves in the heart to control its rhythm. Seloken ZOK also blocks another chemical called adrenaline, which is a hormone (chemical signal carried in the blood) that has similar effects to noradrenaline. Seloken ZOK does this by stopping these chemicals from attaching (binding) to sites, called beta-receptors, in the heart so they can’t produce their effects.
Seloken ZOK reduces the heart rate and is useful in treating abnormally rapid heart rhythms.
It also reduces the force of heart muscle contraction and reduces blood pressure.
By reducing the heart rate and the force of muscle contraction, Seloken ZOK reduces the amount of oxygen that the heart muscle needs. Seloken ZOK is, therefore, helpful in treating angina.
Lowering the blood pressure puts less strain on the heart and therefore Seloken ZOK improves the pumping efficiency of the heart and is used to treat patients with heart failure.
It helps the heart to recover and helps to prevent later complications such as heart failure, arrhythmias or weakness of the heart muscle.

Seloken ZOK is intended for once daily treatment and can be takenwith or without food. The Seloken ZOK tablet should be swallowed with liquid. The tablet can be divided, but should not be chewed or crushed.
It is very important to take this medicine as often as your doctor has told you to, even if you do not feel ill. This is because heart and blood pressure problems, if not treated, can get progressively worse.
It is also important to follow any lifestyle instructions that your doctor has given to you, like trying to give up smoking, reducing your weight, doing more exercise and eating a healthy diet.
