Effects of this medicine
This medicine has calcium antagonistic action to inhibit calcium influx of extracellular fluid into cells, and delays the
excitation-conduction of the heart to correct irregular heart beats due to tachyarrhythmia. It also dilates the
coronary arteries to increase the blood flow to the heart and the peripheral vessels to reduce the work load of the
heart. It consequently suppresses the symptoms such as chest pain due to myocardial ischemia.
It is usually used for treatment of atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia, angina,
myocardial infarction or other ischemic heart diseases.
