Uses Of Isordil

  • Isordil is used in the prevention of angina pectoris and heart failure. It cannot be used in an acute angina episode as its onset of action is not rapid.

How Does Isordil Work?

  • Sublingual Isordil tablet is meant to be kept under the tongue, during an attack of angina pectoris.

Common Dosage Of Isordil

  • The dosage of Isordil depends on severity of disease.
