For adults, the usual dose of Razine tablet for chronic angina is:

• Initial Dose: 500 mg taken orally twice daily.
• Titration: May increase to 1000 mg taken orally twice daily based on clinical response.

How does Razine tablet work?

Razine tablet 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, Razine tablet helps to reduce symptoms of angina (chest pain) and improve exercise tolerance, without significantly affecting heart rate or blood pressure.
