Also Known As: Isosorbide dinitrate, Dilatrate sr, Dilatrate, Isordil, Sorbitrate
Isosorbide dinitrate (ISDN) (also known as Dilatrate) is a nitrate used pharmacologically as a vasodilator, e.g. in angina pectoris but also for anal fissure, a condition which is known to involve decreased blood supply leading to poor healing. It is also used as a direct vasodilator to treat congestive heart failure.
Isosorbide dinitrate is sold under the brand names Isordil by Biovail, Cedocard, Sorbitrate and Isotrate. In UK, Argentina and Hong Kong, a trade name of it is Isoket. It is also a component of BiDil.
It is more useful in preventing angina attacks than reversing them once they have commenced.
