Isosorbide Mononitrate (ISMN)
- OralIsosorbide Mononitrate (ISMN)Imdur, DurideLong-acting, to be used to control stable angina pectoris
- Mechanism of Action
- Converted to nitrous oxide which stimulates vascular smooth muscle relaxation through stimulation of cGMP-dependant protein kinase with resultant reduction in intracellular calcium.
Results in venous dilatation (reduced preload), arterial dilatation (reduced afterload) and coronary dilatation (improved myocardial oxygen supply)
- Stable angina pectoris
- Adverse Effects
