Isosorbide dinitrate is an organic nitrate used in the management of ischemic heart disease and heart failure.

Angina pectoris: rapid relief of chest pain by reducing myocardial oxygen demand. Heart failure: improves symptoms by decreasing preload and afterload. Prophylaxis of exertional angina: prevents episodes of angina during physical activity.

Isoket Spray may cause a range of adverse reactions.

Common Side Effects: - Headache - Flushing - Dizziness - Low blood pressure (hypotension)

Serious or Rare Side Effects: - Severe hypotension - Syncope (fainting) - Methemoglobinemia

Use Isoket Spray with caution and follow medical guidance.

Avoid use in patients with severe anemia: may worsen tissue hypoxia. Monitor blood pressure: risk of hypotension, especially when standing. Use cautiously with phosphodiesterase‑5 inhibitors: additive vasodilation can be dangerous. Do not combine with other nitrates: may cause severe blood pressure drops. Pregnancy and breastfeeding: safety not established; prescribe only if benefit outweighs risk. Store at room temperature: keep in the original container, protect from moisture and light.

Isoket Spray can interact with several drug classes.

Major Interactions (Avoid): - Other nitrates: additive hypotensive effect. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): risk of severe hypotension. - Sodium nitrite: increased nitrate load may precipitate toxicity.

Moderate Interactions (Monitor Closely): - Antihypertensives (ACE inhibitors, beta‑blockers): may enhance blood pressure lowering. - Diuretics: can increase volume depletion. - Alcohol: may intensify vasodilatory responses.
