How does Angiotec tablet er work?

Angiotec tablet er works by inhibiting certain sodium and calcium channels in the heart cells. This reduces the sodium overload in the heart muscle, helping to prevent an increase in intracellular calcium levels, which in turn reduces the heart's oxygen demand. By improving the heart's efficiency in using oxygen, Angiotec tablet er helps to reduce symptoms of angina (chest pain) and improve exercise tolerance, without significantly affecting heart rate or blood pressure.

Who should avoid taking Angiotec tablet er?

Angiotec tablet er should be used with caution in patients with liver disease, as it may affect liver function.
