Isordil

Pronounced: ICE-or-dill
Generic name: Isosorbide dinitrate
Other brand name: Sorbitrate

Why is Isordil prescribed?

Isordil is prescribed to relieve or prevent angina pectoris (suffocating chest pain). Angina pectoris occurs when the arteries and veins become constricted and sufficient oxygen does not reach the heart. Isordil dilates the blood vessels by relaxing the muscles in their walls. Oxygen flow improves as the vessels relax, and chest pain subsides.

In swallowed capsules or tablets, Isordil helps to increase the amount of exercise you can do before chest pain begins.

In chewable or sublingual (held under the tongue) tablets, Isordil can help relieve chest pain that has already started or prevent pain expected from a strenuous activity such as walking up a hill or climbing stairs.

Most important fact about Isordil

Isordil may cause severe low blood pressure (possibly marked by dizziness or fainting), especially when you stand or sit up quickly. People taking diuretic medication or those who have low blood pressure should use Isordil with caution.

How should you take Isordil?

Swallowed capsules or tablets should be taken on an empty stomach. While regular tablets may be crushed for easier use, sustained- or prolonged-release products should not be chewed, crushed or altered.

Chewable tablets should be chewed thoroughly and held in the mouth for a couple of minutes. Do not eat, drink, smoke, or use chewing tobacco while a sublingual tablet is dissolving.

This drug's effectiveness is closely linked to the dose, so follow your doctor's instructions carefully.
