Monoket (Isosorbide Mononitrate)

Isosorbide mononitrate, the active ingredient in Monoket, is a organic nitrate presented as an oral tablet for oral use. It treats chronic stable angina pectoris and helps prevent angina attacks in adult patients.

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

Monoket belongs to the organic nitrate class and is used to manage angina‑related conditions.

- Chronic stable angina pectoris: reduces the frequency and severity of angina episodes. - Prevention of angina attacks: maintains adequate myocardial oxygen supply during daily activities. - Exercise‑induced angina: improves exercise tolerance by decreasing cardiac workload.

Isosorbide mononitrate may cause a range of adverse reactions.

Common Side Effects: - Headache: mild to moderate throbbing pain, often transient. - Dizziness or light‑headedness: related to blood pressure lowering. - Flushing: warm sensation and reddening of skin, especially on the face. - Nausea: occasional upset stomach or vomiting. - Palpitations: awareness of heartbeat acceleration.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure requiring medical attention. - Syncope: sudden loss of consciousness due to inadequate cerebral perfusion. - Myocardial infarction: rare but possible if coronary flow is compromised. - Allergic reaction: rash, itching, swelling, or difficulty breathing. - Stevens‑Johnson syndrome: rare severe skin reaction.

Before initiating therapy, clinicians should consider several safety measures.

- Blood pressure monitoring: check for hypotension, especially after the first dose. - Concomitant nitrates: avoid using other nitrate preparations to prevent excessive vasodilation. - PDE5 inhibitors: do not combine with sildenafil, tadalafil, or similar agents. - Hepatic impairment: use with caution; dose adjustment may be required. - Renal impairment: monitor renal function and adjust dose if necessary. - Pre‑operative use: discontinue at least 24 hours before elective surgery. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Isosorbide mononitrate can interact with several drug classes.

Major Interactions (Avoid): - Other organic nitrates (e.g., nitroglycerin): risk of profound hypotension. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil, tadalafil): may cause severe blood pressure fall. - Potent vasodilators (e.g., hydralazine): additive blood pressure effects.

Moderate Interactions (Monitor Closely): - Antihypertensive agents (ACE inhibitors, beta‑blockers): may enhance hypotensive response. - Diuretics: increased risk of volume depletion and low blood pressure. - Alcohol: can potentiate vasodilatory effects and dizziness. - Smoking: induces metabolism, potentially reducing efficacy.
