Modisal Xl (Isosorbide Mononitrate)

Isosorbide mononitrate, the active ingredient in Modisal Xl, is a nitrate vasodilator presented as an oral tablet for systemic use. It is employed to relieve angina pectoris by improving myocardial oxygen balance in adult patients with coronary artery disease. The drug’s rapid absorption and predictable nitrate release allow consistent therapeutic effect throughout the day.

GNH USA supplies Modisal Xl as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, adhering to stringent quality standards and regulatory requirements across EU and global markets.

Isosorbide mononitrate is used in the management of coronary artery disease‑related conditions, primarily targeting angina. - Angina pectoris: reduces frequency and severity of chest pain episodes by decreasing myocardial oxygen demand. - Chronic stable angina: improves exercise tolerance and prevents angina attacks during physical activity.

Isosorbide mononitrate may cause a range of adverse reactions, which are classified by frequency and severity.

Common Side Effects: - Headache: throbbing pain often occurring shortly after dosing. - Dizziness or light‑headedness: due to transient blood pressure reduction. - Flushing: warm sensation and reddening of the skin. - Nausea: mild gastrointestinal upset.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure leading to fainting. - Syncope: sudden loss of consciousness associated with vasodilation. - Allergic reactions: rash, itching, swelling, or anaphylaxis in rare cases.

When prescribing or dispensing Modisal Xl, consider the following precautions to ensure safe use. - Discontinue abruptly: sudden stop may precipitate rebound angina; tapering is recommended. - Monitor blood pressure: check for hypotension especially after dose initiation. - Concomitant PDE‑5 inhibitors: avoid co‑administration due to risk of profound hypotension. - Hepatic impairment: use with caution as metabolism may be altered. - Pregnancy and lactation: safety not established; avoid unless benefits outweigh risks. - Store at ambient temperature: keep below 25 °C in original packaging, protected from moisture.

Isosorbide mononitrate interacts with several medicines; awareness of these interactions helps prevent adverse events.

Major Interactions (Avoid): - Other nitrates (e.g., nitroglycerin): additive vasodilation can cause severe hypotension. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): may lead to dangerous blood pressure drops. - Alcohol: excessive intake can enhance hypotensive effects.

Moderate Interactions (Monitor Closely): - Antihypertensive agents (e.g., ACE inhibitors, beta‑blockers): may increase blood‑pressure‑lowering effect. - Diuretics: can cause volume depletion and accentuate hypotension. - Azole antifungals (e.g., ketoconazole): may raise plasma levels of isosorbide mononitrate.
