HOW DO ANTIANGINAL AGENTS WORK?

Antianginal agents are drugs used to provide immediate relief from angina symptoms and prevent angina attacks.

Angina is chest pain or discomfort that happens because of reduced blood flow to the heart. Angina results from an imbalance in the oxygen supply/demand ratio. Due to the lower oxygen supply and greater oxygen demand, there is increased pressure on the heart. Constriction of blood vessels and formation of blood clots may be the major reason for disturbing the oxygen supply/demand ratio. 

Antianginal drugs act by:

  • Increasing blood flow to the heart
  • Increasing oxygen supply to the heart
  • Dilating the blood vessels to reduce the load on the heart
  • Preventing clot formation in the blood vessels
  • Reducing oxygen demand by decreasing heart rate and contraction
