Imdur

Isosorbide Mononitrate, the active ingredient in Imdur, is a nitrate vasodilator presented as an oral tablet for oral use. It is employed to prevent episodes of angina pectoris in patients with chronic coronary artery disease. GNH USA supplies Imdur as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Imdur belongs to the nitrate class of antianginal agents and is used to manage coronary artery disease‑related chest pain. - Angina pectoris (stable): Reduces the frequency and severity of chest pain episodes. - Chronic stable angina: Improves exercise tolerance and delays onset of pain. - Ischemic heart disease: Lowers myocardial oxygen demand by decreasing cardiac preload and afterload.

Isosorbide mononitrate may cause a range of adverse reactions.

Common Side Effects: - Headache: often mild to moderate and transient. - Dizziness or light‑headedness: related to blood pressure lowering. - Flushing: warm sensation, usually short‑lived. - Nausea: occasional gastrointestinal upset.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure requiring medical attention. - Syncope: fainting episodes due to inadequate cerebral perfusion. - Allergic reaction: rash, itching, or swelling that may progress to anaphylaxis. - Worsening angina: paradoxical increase in chest pain in rare cases.

Before initiating Imdur, several safety considerations should be observed. - Avoid abrupt discontinuation: may precipitate rebound angina. - Monitor blood pressure: risk of symptomatic hypotension, especially on standing. - Use with caution in hepatic impairment: metabolism may be reduced. - Do not combine with phosphodiesterase‑5 inhibitors: can cause profound hypotension. - Store at room temperature: keep in the original container, protect from moisture and light.

Isosorbide mononitrate interacts with several drug classes; awareness helps prevent adverse events.

Major Interactions (Avoid): - Other nitrates (e.g., nitroglycerin): additive vasodilation leading to severe hypotension. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): risk of profound blood pressure fall.

Moderate Interactions (Monitor Closely): - Antihypertensives (ACE inhibitors, beta‑blockers): may enhance blood‑pressure‑lowering effect. - Alcohol: can increase hypotensive response. - Diuretics: may cause electrolyte disturbances and augment blood‑pressure changes.
