The therapeutic effect of isosorbide mononitrate sustained-release capsules lasts over 20 hours. For myocardial ischemia caused by coronary atherosclerosis, these capsules can also be used as a preventive medication for angina pectoris, helping to dilate blood vessels. At the beginning of treatment, patients may experience headaches or facial flushing due to vasodilation.

This medication must not be discontinued abruptly, as doing so may lead to rebound worsening of myocardial ischemia.

After taking isosorbide mononitrate sustained-release capsules, monitor your condition closely. If any discomfort occurs, consult your doctor immediately and adjust the dosage according to medical advice.
