Isosorbide Dinitrate 10 mg Tablets
Product Overview
Isosorbide dinitrate is a nitrate medication used to prevent and manage angina pectoris (chest pain) associated with coronary artery disease. It works by relaxing and widening blood vessels, improving blood flow to the heart muscle, thereby reducing its workload and oxygen demand.
Indications
Angina Pectoris: Prevention and long-term management of angina episodes.
Heart Failure: May be used in combination with other medications for the treatment of heart failure.
Dosage and Administration
Dosage: The typical starting dose is 5 to 20 mg taken two or three times daily. Maintenance doses range from 10 to 40 mg two or three times daily. It's essential to follow your healthcare provider's specific dosing instructions. :contentReference[oaicite:0]{index=0}
Administration: Take the tablet orally with a full glass of water. To minimize the risk of developing tolerance, it's crucial to have a daily dose-free interval of at least 14 hours. Do not crush or chew the tablet; swallow it whole.
Precautions
Avoid Concurrent Use with PDE5 Inhibitors: Do not use isosorbide dinitrate with medications for erectile dysfunction (e.g., sildenafil, tadalafil) as this combination can cause a significant drop in blood pressure. :contentReference[oaicite:1]{index=1}
Hypotension: Monitor blood pressure regularly, as this medication can cause low blood pressure, leading to dizziness or fainting. Rise slowly from sitting or lying positions to reduce the risk of dizziness.
Tolerance: Continuous use can lead to tolerance, reducing the medication's effectiveness. Ensure dosing schedules include a nitrate-free period each day to prevent this.
