Nitrosorbide is one of the main antianginal organic nitrates for oral use. In the form of special dosage forms is available for sublingual, intravenous and inhalation use.

When taken orally in the form of tablets, the onset of action of nitrosorbide is noted after 30 - 50 minutes, the maximum effect - after 1, 5 - 2 hours, the total duration of action - 4 - 6 hours or more.

Nitrosorbide is widely prescribed as an antianginal agent in the chronic course of IHD to prevent attacks; with infrequent attacks of stable angina pectoris. Take before meals, usually 0.005 - 0.01 g (5 - 10 mg) 3-4 times a day. Sometimes patients require higher single doses (20-30 mg) (According to existing data, in order to avoid the development of tolerance, it is advisable to take nitrosorbide 30 mg 2 times a day: at 8 a.m. and 1 p.m., i.e. "the period of greatest physical activity. From 13 p.m. to 8 p.m. the next morning, sensitivity to the drug is restored.).

Applied sublingually (in the form of conventional tablets) nitrosorbide can stop an attack of angina pectoris, but more slowly than nitroglycerin (after 3 - 5 minutes).

In recent years, nitrosorbide, like nitroglycerin, began to be used as a peripheral vasodilator in severe forms of heart failure. Reducing the tone of peripheral venous vessels (venules), the drug reduces venous blood flow to the heart, pressure in the vessels of the small circle, shortness of breath, suffocation, cyanosis. It is taken orally at 20 mg (2 tablets) every 4 to 5 hours.

With prolonged use of nitrosorbide, tolerance may develop, and therefore it is recommended after 3 to 6 weeks of regular tablets to take a break for 3 to 5 days, replacing nitrosorbide with other antianginal drugs.
