Imdur

Isosorbide Mononitrate, the active ingredient in Imdur, is a nitrate vasodilator presented as an oral tablet for oral use. It is employed in the prophylaxis of angina pectoris and the management of chronic stable angina in adult patients, reducing myocardial oxygen demand and improving exercise tolerance.

GNH USA supplies Imdur as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring quality, regulatory compliance and reliable global distribution.

Imdur, a nitrate vasodilator, is used in the treatment of coronary artery disease‑related conditions. - Angina pectoris: reduces the frequency and severity of anginal attacks. - Chronic stable angina: improves exercise tolerance and decreases symptom burden. - Ischemic heart disease: helps prevent episodes of myocardial ischemia in patients with established disease.

Adverse reactions may occur with any nitrate therapy.

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

Serious or Rare Side Effects: - Severe hypotension: may cause syncope or shock. - Reflex tachycardia: rapid heart rate in response to vasodilation. - Methemoglobinemia: rare blood disorder presenting with cyanosis. - Allergic reactions: rash, pruritus, or anaphylaxis. - Myocardial infarction: extremely rare but reported.

Before prescribing Imdur, clinicians should consider several safety measures. - Cardiovascular assessment: evaluate blood pressure and heart rate prior to initiation. - Concomitant PDE‑5 inhibitors: avoid due to risk of profound hypotension. - Tolerance development: monitor efficacy over time and adjust therapy if needed. - Renal impairment: use caution and consider dose adjustment. - Store at room temperature: keep in original packaging, protect from moisture and direct sunlight.

Isosorbide mononitrate may interact with several drug classes.

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

Moderate Interactions (Monitor Closely): - Antihypertensives (ACE inhibitors, beta‑blockers): may increase blood‑pressure lowering. - Diuretics: can potentiate volume depletion and hypotension. - Antiplatelet agents (e.g., aspirin, clopidogrel): monitor for increased bleeding risk.
