Isoket

Isosorbide dinitrate, the active ingredient in Isoket, is an organic nitrate presented as an oromucosal tablet for oromucosal use. It treats angina pectoris and is used for prophylaxis of angina in adult patients. GNH USA supplies Isoket as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Isoket, an organic nitrate, is employed in the management of coronary artery disease‑related chest pain. - Angina pectoris: reduces the frequency and severity of chest pain episodes. - Prophylaxis of angina: helps prevent angina attacks during physical exertion or stress. - Chronic stable angina: improves exercise tolerance by decreasing myocardial oxygen demand.

Isoket may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Headache: throbbing pain often occurring shortly after dosing. - Flushing: warmth and redness of the face or neck. - Dizziness or light‑headedness: especially on standing. - Hypotension: noticeable drop in blood pressure causing faintness.

Serious or Rare Side Effects: - Severe hypotension: may lead to syncope or shock. - Reflex tachycardia: rapid heart rate in response to blood pressure fall. - Methemoglobinemia: rare discoloration of blood causing cyanosis.

Before prescribing Isoket, clinicians should consider several safety factors. - Concomitant nitrate therapy: avoid combined use to prevent profound hypotension. - Phosphodiesterase‑5 inhibitors: contraindicated due to risk of severe blood pressure loss. - Cardiovascular instability: use cautiously in patients with recent myocardial infarction or unstable angina. - Hepatic or renal impairment: monitor closely as clearance may be altered. - Store at ambient temperature: keep below 25°C in the original container, protected from moisture and direct sunlight.

Isoket interacts with several drug classes that can modify its hemodynamic effects.

Major Interactions (Avoid): - Other organic nitrates or nitroglycerin: additive vasodilatory effect leading to dangerous hypotension. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): risk of severe blood pressure reduction.

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