MONOTRATE 10MG

# Isosorbide Mononitrate 10 mg ## SHORT DESCRIPTION **Isosorbide Mononitrate 10 mg** is a **nitrate medicine** used primarily to prevent **angina (chest pain)** caused by reduced blood flow to the heart muscle. It works by relaxing and widening blood vessels, reducing the workload on the heart and lowering its oxygen demand. Isosorbide mononitrate is generally used for **prevention of angina attacks** and is **not intended to provide rapid relief of an acute angina attack**. ## KEY BENEFITS * Helps prevent episodes of angina * Relaxes and widens blood vessels * Reduces the workload on the heart * Reduces the amount of oxygen required by the heart * Helps improve blood flow through the coronary circulation * May improve exercise tolerance in people with stable angina * Supports long-term management of chronic stable angina when prescribed ## USES / INDICATIONS Isosorbide Mononitrate 10 mg may be prescribed for: * **Prevention of chronic stable angina** * Prevention of recurrent chest pain due to coronary artery disease * Other nitrate-responsive cardiovascular conditions when specifically prescribed > **Important:** Isosorbide mononitrate is primarily a **preventive medicine**. It should not be relied upon for immediate relief of sudden chest pain. ## HOW IT WORKS Isosorbide mononitrate is converted to **nitric oxide (NO)** in the body. Nitric oxide activates an enzyme pathway that increases **cyclic GMP**, causing the smooth muscles in blood-vessel walls to relax. This results in: * Widening of veins and arteries * Reduced blood returning to the heart * Reduced pressure and workload on the heart * Lower oxygen demand by the heart * Improved balance between oxygen supply and demand These effects help prevent angina caused by inadequate oxygen supply to the heart muscle. ## DOSAGE & ADMINISTRATION The dose and schedule depend on the formulation and individual clinical needs. * Take Isosorbide Mononitrate 10 mg exactly as prescribed. * It may generally be taken with or without food. * Take it at the same time(s) each day as directed. * Swallow tablets with water unless the product is specifically designed for another method of administration. * Do not change the dose without medical advice. ### Nitrate-free interval Regular nitrate therapy may require a **daily nitrate-free interval** to reduce the development of tolerance. The exact schedule depends on whether the product is immediate-release or modified-release. **Do not create or change the nitrate-free interval yourself.** Follow your doctor's specific dosing schedule. ### Missed dose Take the missed dose when remembered unless it is close to the next scheduled dose. Do not take two doses together. ### Acute chest pain Isosorbide mononitrate is **not a rapid-acting rescue medicine** for an acute angina attack. Follow your prescribed emergency plan, which may include sublingual or spray nitroglycerin. If chest pain is new, severe, prolonged, or different from usual, seek emergency medical attention. ## SIDE EFFECTS Common side effects may include: * Headache * Dizziness * Lightheadedness * Flushing * Low blood pressure * Weakness * Nausea * Increased heart rate ### Headache Headache is particularly common when nitrate treatment is started and may decrease as the body becomes accustomed to the medicine. ### Serious side effects Seek medical attention for: * Severe or persistent dizziness * Fainting * Very low blood pressure * Rapid or irregular heartbeat * Severe allergic reaction * Worsening or persistent chest pain ## PRECAUTIONS & WARNINGS ### Low blood pressure Isosorbide mononitrate can significantly lower blood pressure. Use caution if you already have low blood pressure or are prone to dizziness or fainting. ### Sudden withdrawal Do not stop long-term nitrate therapy suddenly without medical advice, as angina symptoms may worsen. ### Heart conditions Tell your doctor if you have: * Severe anemia * Low blood pressure * Recent head injury * Increased pressure inside the skull * Certain heart-valve disorders * Hypertrophic cardiomyopathy ### Alcohol Alcohol may increase the blood-pressure-lowering effects of isosorbide mononitrate and increase dizziness or fainting. ### Elderly patients Older adults may be more sensitive to blood-pressure changes and dizziness and may require careful monitoring. ### Pregnancy Use during pregnancy only when specifically recommended by a healthcare professional. ### Breastfeeding Consult your healthcare professional before using isosorbide mononitrate while breastfeeding. ## DRUG INTERACTIONS ### PDE-5 inhibitors — IMPORTANT **Do NOT combine isosorbide mononitrate with PDE-5 inhibitors**, including: * **Sildenafil** * **Tadalafil** * **Vardenafil** * **Avanafil** The combination can cause a **dangerous and potentially life-threatening drop in blood pressure**. ### Other medicines that lower blood pressure The effects may be increased when combined with: * ACE inhibitors * ARBs * Beta-blockers * Calcium-channel blockers * Diuretics * Other antihypertensive medicines ### Alcohol Alcohol can increase dizziness and hypotension. ### Other nitrate medicines Taking multiple nitrate-containing medicines can increase the risk of excessive blood-pressure reduction and nitrate tolerance. Tell your doctor or pharmacist about all prescription medicines, OTC medicines, vitamins, and herbal supplements you take. ## STORAGE INFORMATION * Store Isosorbide Mononitrate 10 mg according to the manufacturer's instructions. * Keep at room temperature unless the product label specifies otherwise. * Protect from excessive heat, moisture, and direct sunlight. * Keep tablets in their original packaging. * Keep the container tightly closed. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use tablets if the packaging is damaged or the medicine appears abnormal. ## PRESCRIPTION STATUS **Isosorbide Mononitrate 10 mg is generally a prescription medicine.** It should be used under medical supervision because the dose, formulation, dosing interval, cardiovascular condition, and potential drug interactions require appropriate assessment. ## GENUINE MEDICINE ASSURANCE To help ensure you receive genuine Isosorbide Mononitrate 10 mg: * Purchase only from a licensed and reputable pharmacy. * Check the medicine name and **10 mg strength**. * Verify the manufacturer and formulation. * Check the batch number and expiry date. * Ensure the packaging is sealed and undamaged. * Confirm whether the product is immediate-release or modified-release. * Avoid products with suspicious or altered packaging. * Consult a pharmacist if you have concerns about authenticity. ## FAQ SECTION ### What is Isosorbide Mononitrate 10 mg used for? Isosorbide Mononitrate 10 mg is mainly used to **prevent angina (chest pain)** associated with coronary artery disease. ### Is Isosorbide Mononitrate a blood pressure medicine? It can lower blood pressure because it widens blood vessels, but its primary use is generally **prevention of angina**, rather than treatment of uncomplicated hypertension. ### How does Isosorbide Mononitrate work? It releases nitric oxide, which relaxes blood vessels and reduces the workload and oxygen demand of the heart. ### Is Isosorbide Mononitrate a nitrate? Yes. It belongs to the **organic nitrate** class of medicines. ### Does Isosorbide Mononitrate stop chest pain immediately? No. Isosorbide mononitrate is generally used to **prevent angina**, not to provide rapid relief during an acute attack. ### What should I take for sudden angina? Use the rapid-acting medicine prescribed in your angina action plan, commonly sublingual or spray nitroglycerin. If chest pain is severe, new, persistent, or does not improve as directed, seek emergency medical attention. ### Can Isosorbide Mononitrate prevent angina? Yes. Preventing angina is one of its primary uses. ### Can Isosorbide Mononitrate be taken every day? Yes, when prescribed. The dosing schedule is designed to provide protection while often incorporating a nitrate-free period to reduce tolerance. ### Why is a nitrate-free interval needed?
