Isomex

Isosorbide Mononitrate, the active ingredient in Isomex, is an organic nitrate presented as an oral tablet for systemic use. It is employed to manage chronic stable angina pectoris and to help prevent angina attacks in adult patients. The medication dilates veins and arteries, lowering cardiac preload and afterload while enhancing myocardial oxygen supply.

GNH USA supplies Isomex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, with a distribution network that ensures timely delivery and adherence to global quality standards.

Isosorbide Mononitrate is used in the management of coronary artery disease‑related angina.

Chronic stable angina pectoris: reduces the frequency and severity of chest pain episodes. Prevention of angina attacks: provides sustained symptom control to lower the risk of acute episodes. Exercise‑induced angina: improves exercise tolerance by enhancing myocardial oxygen delivery.

Isosorbide Mononitrate may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Headache - Dizziness or light‑headedness - Flushing - Nausea

Serious or Rare Side Effects: - Severe hypotension leading to syncope - Methemoglobinemia - Anaphylactic reaction - Cardiac arrhythmias

When prescribing Isosorbide Mononitrate, clinicians should observe several precautionary measures to ensure patient safety.

Assess cardiovascular status: measure blood pressure and heart rate before initiating therapy. Avoid concurrent PDE‑5 inhibitors: combined use can cause profound hypotension. Monitor for tolerance development: efficacy may diminish with prolonged use. Adjust dose in renal impairment: use caution in patients with severe renal dysfunction. Pregnancy and lactation: safety not established; prescribe only if benefit outweighs potential risk. Store at ambient temperature: keep below 25 °C, protect from moisture and light in the original packaging.

Isosorbide Mononitrate can interact with several medicines, altering its effect or safety profile.

Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil, tadalafil): may cause severe hypotension. - Other organic nitrates (e.g., nitroglycerin, isosorbide dinitrate): additive vasodilatory effect. - Alcohol: enhances hypotensive response.

Moderate Interactions (Monitor Closely): - Antihypertensive agents (ACE inhibitors, beta‑blockers, calcium channel blockers): may require dose adjustment. - Diuretics: increase risk of low blood pressure. - Azole antifungals (e.g., ketoconazole): may raise plasma concentrations of isosorbide mononitrate.
