Angina pectoris is defined as a sudden, sharp, severe pain originating from the apex of heart and radiating to the left shoulder. The pain is severe and crushing, and it is characterized by feeling of pressure and suffocation, behind breastbone. It can also help to control certain types of heart failure.

Isosorbide-5-mononitrate works by relaxing the blood vessels of the heart and this reduces the strain on the heart making it easier to pump blood.

USES OF MONIT 20MG

Prevents angina pectoris

HOW MONIT 20MG WORKS

After administration, isosorbide-5-mononitrate is converted into free radical nitric oxide which activates the enzyme guanylate cyclase. Activation of this enzyme is followed by synthesis of cyclic guanosine 3′,5′-monophosphate (cyclic GMP) in smooth muscle and other tissues. This process leads to dephosphorylation of myosin light chain of smooth muscles, and results in relaxation and increased blood flow in arteries, veins and cardiac tissue (vasodilatation), this in turn decreases cardiac workload and provides relief from anginal symptoms.
