Monocinque (Isosorbide 5 Mononitrate)

Isosorbide 5 Mononitrate, the active ingredient in Monocinque, is a nitrate vasodilator presented as an oral formulation for oral use. It is used for the prevention and treatment of chronic stable angina pectoris in adults. GNH USA supplies Monocinque as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Isosorbide 5 Mononitrate is indicated for conditions involving myocardial oxygen demand and supply imbalance. - Chronic stable angina: reduces the frequency of chest pain episodes during daily activities. - Exercise‑induced angina: improves exercise tolerance by decreasing cardiac workload. - Angina prophylaxis: helps prevent angina attacks during physical or emotional stress.

Isosorbide 5 Mononitrate may cause a range of adverse reactions.

Common Side Effects: - Headache: mild to moderate, often transient. - Flushing: warm sensation, especially after the first dose. - Dizziness or light‑headedness: related to blood pressure reduction. - Nausea or abdominal discomfort. - Palpitations: sensation of irregular heartbeat.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure requiring medical attention. - Syncope: fainting episodes. - Methemoglobinemia: rare discoloration of blood. - Allergic reactions: rash, itching, or swelling. - Chest pain worsening: paradoxical increase in angina.

Before prescribing Isosorbide 5 Mononitrate, consider the following safety measures. - Cardiovascular assessment: evaluate blood pressure and heart rate baseline. - Concomitant nitrates: avoid combined use to prevent severe hypotension. - Phosphodiesterase‑5 inhibitors: contraindicated due to risk of profound vasodilation. - Hepatic or renal impairment: adjust monitoring as clearance may be affected. - Pregnancy and lactation: use only if potential benefit justifies potential risk. - Store at ambient temperature: keep below 25°C in the original container, protect from moisture and direct sunlight.

Isosorbide 5 Mononitrate can interact with several drug classes.

Major Interactions (Avoid): - Other nitrates (e.g., nitroglycerin): may cause dangerous drops in blood pressure. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): risk of severe hypotension.

Moderate Interactions (Monitor Closely): - Antihypertensives (e.g., ACE inhibitors, beta‑blockers): additive blood pressure‑lowering effect. - Diuretics: may enhance orthostatic hypotension. - Alcohol: can increase vasodilatory response and dizziness.
