Isosorbide Dinitrate

Isoket (Isosorbide dinitrate) is an organic nitrate of medium-long duration that is used in the treatment and prevention of angina pectoris. Isosorbide dinitrate produces a direct relaxation of the vascular smooth muscle fiber, which is independent of the presence or absence of endothelium. The normal recommended dose is Isoket 1 tablet every 3-4 hours, ingested whole, without chewing, with a sufficient amount of liquid. On the other hand, the rapid absorption of isosorbide dinitrate sublingually means that this medicine can also be used in emergency situations, such as in acute angina attacks.
