Ismo Retard (Isosorbide 5 Mononitrate)

Isosorbide 5‑Mononitrate, the active ingredient in Ismo Retard, is a nitrate vasodilator presented as an extended‑release tablet for oral use. It is employed to prevent angina attacks and to manage chronic stable angina in adult patients.

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

Ismo Retard, a nitrate vasodilator, is used in the management of coronary artery disease‑related chest pain. - Prophylaxis of angina pectoris: reduces the frequency of angina episodes. - Chronic stable angina: improves exercise tolerance and reduces pain on exertion. - Ischemic heart disease: decreases myocardial oxygen demand, helping to prevent ischemic episodes.

Ismo Retard may cause a range of adverse reactions, most of which are dose‑related and reversible.

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

Serious or Rare Side Effects: - Severe hypotension: marked blood pressure fall requiring medical attention. - Syncope: fainting episodes due to sudden circulatory changes. - Life‑threatening allergic reaction: rash, swelling, or difficulty breathing. - Methemoglobinemia: rare blood disorder causing reduced oxygen delivery. - Myocardial infarction: extremely rare but reported in vulnerable patients. - Life‑threatening arrhythmias: abnormal heart rhythms requiring urgent care.

Before prescribing Ismo Retard, clinicians should evaluate patient‑specific risk factors and monitor for adverse events. - Blood pressure assessment: ensure baseline values are stable before initiation. - Concomitant PDE‑5 inhibitors: avoid due to risk of profound hypotension. - Use with other nitrates: contraindicated because of additive vasodilatory effects. - Hepatic impairment: dose adjustment may be required; monitor liver function. - Elderly patients: start at the lowest effective dose and titrate cautiously. - Store at ambient temperature: keep in the original container, protect from moisture and light.

Ismo Retard can interact with several drug classes, requiring careful management.

Major Interactions (Avoid): - Phosphodiesterase‑5 inhibitors (e.g., sildenafil, tadalafil): risk of severe hypotension. - Other organic nitrates (e.g., nitroglycerin, isosorbide dinitrate): additive vasodilation leading to dangerous blood pressure drops. - Sodium nitroprusside: combined nitrate effect may cause profound hypotension.

Moderate Interactions (Monitor Closely): - Antihypertensive agents (ACE inhibitors, beta‑blockers, calcium channel blockers): may enhance blood pressure‑lowering effect. - Diuretics: can increase orthostatic hypotension risk. - Alcohol: potentiates vasodilatory response and dizziness.
