Isoprenaline Macure

Isoprenaline, the active ingredient in Isoprenaline Macure, is a beta‑adrenergic agonist presented as an injectable solution for intravenous use. It is employed to increase heart rate and contractility in bradyarrhythmias and to provide bronchodilation in severe bronchospasm, typically in acute care settings.

GNH USA supplies Isoprenaline Macure as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide.

Isoprenaline acts on the beta‑adrenergic system and is indicated for several acute cardiac and respiratory conditions.

- Bradycardia: restores adequate heart rate by stimulating cardiac beta‑1 receptors. - Heart block: improves conduction through the atrioventricular node by increasing impulse speed. - Asystole: provides temporary cardiac stimulation while definitive resuscitation measures are applied. - Bronchospasm: relaxes airway smooth muscle to relieve severe bronchoconstriction.

Isoprenaline may produce a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Tachycardia: excessive increase in heart rate. - Palpitations: sensation of rapid or irregular heartbeat. - Tremor: fine muscle shaking, especially in the hands. - Headache: mild to moderate cranial pain. - Nausea: feeling of queasiness or urge to vomit.

Serious or Rare Side Effects: - Arrhythmias: potentially life‑threatening irregular heart rhythms. - Myocardial ischemia: reduced blood flow to heart muscle causing chest pain. - Severe hypotension: marked drop in blood pressure leading to dizziness or collapse. - Pulmonary edema: fluid accumulation in lungs causing respiratory distress.

When using Isoprenaline, clinicians should observe several safety measures to minimize risk.

- Cardiac monitoring: continuous ECG and blood pressure observation during infusion. - Dose titration: adjust infusion rate gradually based on hemodynamic response. - Contraindications: avoid in patients with uncontrolled ventricular tachyarrhythmias or severe coronary artery disease. - Drug interactions: review concomitant use of other sympathomimetics or anti‑arrhythmic agents. - Store at ambient temperature: keep in original container, protect from light and moisture, and do not freeze.

Isoprenaline can interact with other medications, altering its efficacy or safety profile.

Major Interactions (Avoid): - Beta‑blockers: may blunt the cardiovascular effects of Isoprenaline. - Calcium channel blockers (non‑dihydropyridine): increase risk of severe bradycardia or heart block. - Monoamine oxidase inhibitors: can potentiate hypertensive responses.

Moderate Interactions (Monitor Closely): - Diuretics: may exacerbate electrolyte imbalances affecting cardiac rhythm. - Anticholinergic agents: can enhance tachycardia. - Inhaled bronchodilators: additive bronchodilatory effect may cause excessive tachycardia.
