Isorem

Isosorbide dinitrate, the active ingredient in Isorem, is a nitrate vasodilator presented as a sublingual formulation for sublingual use. It is employed to relieve acute episodes of angina pectoris and to reduce the frequency of angina attacks in patients with coronary artery disease.

GNH USA supplies Isorem as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides reliable sourcing for regulated markets. Our distribution network ensures timely delivery and compliance with local regulatory requirements.

Isosorbide dinitrate is a nitrate vasodilator used in the management of angina.

Acute angina pectoris: provides rapid relief of chest pain by dilating coronary vessels. Prophylaxis of angina: reduces the frequency of angina attacks during daily activities. Chronic stable angina: improves exercise tolerance by decreasing myocardial oxygen demand.

Isosorbide dinitrate may cause a range of adverse reactions, most of which are dose‑related and transient.

Common Side Effects: - Headache: throbbing pain often occurring shortly after administration. - Dizziness or light‑headedness: due to reduced blood pressure. - Flushing: warm sensation and reddening of the skin. - Hypotension: noticeable drop in blood pressure, especially when standing. - Nausea: mild gastrointestinal discomfort. - Palpitations: awareness of heartbeat acceleration.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure requiring medical attention. - Syncope: sudden loss of consciousness. - Methemoglobinemia: abnormal hemoglobin that impairs oxygen delivery. - Reflex tachycardia: rapid heart rate as a compensatory response. - Allergic reactions: rash, itching, or swelling that may progress to anaphylaxis. - Ischemic paradox: worsening chest pain despite therapy.

Before prescribing Isosorbide dinitrate, clinicians should consider several safety aspects.

Avoid use in patients with severe hypotension: monitor blood pressure before administration. Do not combine with phosphodiesterase‑5 inhibitors: risk of profound hypotension. Use with caution in patients with anemia or increased intracranial pressure: may exacerbate symptoms. Educate patients on proper sublingual placement: avoid swallowing the tablet. Pregnancy and lactation: safety not established; weigh benefits against potential risks. Store at room temperature: keep in original container, protect from moisture and light.

Isosorbide dinitrate can interact with several drug classes, requiring careful management.

Major Interactions (Avoid): - Sildenafil and other PDE‑5 inhibitors: may cause severe hypotension. - Concurrent nitrates (e.g., nitroglycerin): additive vasodilatory effect leading to dangerous blood pressure drops. - Alcohol: enhances hypotensive effect and may increase dizziness.

Moderate Interactions (Monitor Closely): - Antihypertensives (ACE inhibitors, beta‑blockers): may augment blood pressure‑lowering effect. - Diuretics: can potentiate orthostatic hypotension. - Azole antifungals (e.g., ketoconazole): may increase plasma levels of isosorbide dinitrate.
