Isordil

Isosorbide dinitrate, the active ingredient in Isordil, is a nitrate vasodilator presented as a sublingual formulation for sublingual use. It treats angina pectoris and heart failure in adult patients.

GNH USA supplies Isordil as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Isordil (isosorbide dinitrate) is used in the management of coronary artery disease and related cardiac conditions.

- Angina pectoris: provides rapid relief of chest pain by reducing myocardial oxygen demand. - Chronic stable angina: maintains symptom control with scheduled dosing. - Heart failure: improves functional status by decreasing preload and afterload. - Prophylaxis of angina attacks: lowers the frequency of episodes when taken regularly.

Isordil may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Headache - Dizziness - Flushing - Mild hypotension

Serious or Rare Side Effects: - Severe hypotension - Syncope - Allergic reaction (anaphylaxis)

Before prescribing Isordil, clinicians should consider several safety measures.

- Avoid use with phosphodiesterase‑5 inhibitors: risk of profound hypotension. - Monitor blood pressure: may cause symptomatic hypotension, especially on standing. - Use caution in patients with anemia: nitrates can exacerbate symptoms. - Adjust dose in renal or hepatic impairment: clearance may be reduced. - Do not discontinue abruptly: may precipitate rebound angina. - Store at room temperature: keep in the original container, protect from moisture and light.

Isordil interacts with several drug classes; some require avoidance while others need close monitoring.

Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): can cause severe hypotension. - Other nitrates: additive vasodilation may lead to dangerous blood pressure drops. - Antihypertensive agents: may produce excessive hypotension.

Moderate Interactions (Monitor Closely): - Alcohol: can enhance hypotensive effects. - Diuretics: may increase the risk of low blood pressure. - Beta‑blockers: may mask tachycardia that signals hypotension.
