Isosorbide dinitrate sustained-release capsules

The main pharmacological effect of isosorbide dinitrate (ISDN) is to relax vascular smooth muscle. ISDN is metabolized in the body to form isosorbide mononitrate (ISMN), which releases nitric oxide (NO). NO is the same as endothelial relaxing factor, activating guanylate cyclase, increasing cyclic guanosine monophosphate (cGMP) in smooth muscle cells, thereby relaxing vascular smooth muscle, dilating peripheral arteries and veins, and having a stronger dilating effect on veins. Venous dilation causes blood to remain in the periphery, reducing the amount of blood returning to the heart, and reducing left ventricular end-diastolic pressure and pulmonary capillary wedge pressure (preload). Arterial dilation reduces peripheral vascular resistance, systolic arterial pressure, and mean arterial pressure (afterload). Coronary artery dilation increases coronary perfusion. The overall effect is to reduce myocardial oxygen consumption, increase oxygen supply, and relieve angina pectoris. Prevent and treat angina pectoris caused by coronary artery disease.

Main ingredients: The chemical name of this product is: 1,4,3,6-dianhydro-D-sorbitol dinitrate. Molecular formula: C6H8N2O8 Molecular weight: 236.14

This medicine is a white or nearly white spherical capsule with small particles.

Prevention and treatment of angina pectoris caused by coronary artery disease.

Adults: 20-40 mg each time, 1-2 times a day.

In the early stage of medication, nitrate-induced vasodilatory headache may occur, as well as facial flushing, dizziness, orthostatic hypotension and reflex tachycardia. Occasionally, blood pressure may be significantly reduced, bradycardia and angina pectoris may be aggravated, and collapse and syncope may rarely occur.

Acute circulatory failure (shock, circulatory collapse); severe hypotension (systolic blood pressure 90 mmHg); acute myocardial infarction with low filling pressure (unless under continuous hemodynamic monitoring); hypertrophic obstructive cardiomyopathy; constrictive pericarditis or cardiac tamponade; severe anemia; glaucoma; increased intracranial pressure; primary pulmonary hypertension; allergy to nitro compounds; allergy to isosorbide dinitrate or any ingredient of this product.

Precautions for children: The safety and effectiveness of this product in children have not been established. Precautions for pregnancy and lactation: Women in the first 3 months of pregnancy are prohibited from using this product, and lactating women should use this product with caution. Precautions for the elderly: Not yet clear.

The combination of this drug with other vasodilators, calcium antagonists, beta-receptor blockers, antihypertensive drugs, tricyclic antidepressants and alcohol can enhance the blood pressure lowering effect of this drug. It can also enhance the pressor effect of dihydroergot alkaloids. The simultaneous use of steroid anti-inflammatory drugs can reduce the efficacy of this drug.

Keep in a light-proof and sealed container. The validity period is tentatively 2 years.
