Isoprenaline Macure

Isoprenaline Hydrochloride, 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 bradycardia or heart block and to produce bronchodilation in asthma and bronchospasm. GNH USA supplies Isoprenaline Macure as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Isoprenaline is a non‑selective beta‑adrenergic agonist used in cardiovascular and respiratory conditions where stimulation of β‑receptors is required.

- Bradycardia: raises heart rate to relieve symptomatic slow rhythms. - Heart block: improves atrioventricular conduction by enhancing myocardial contractility. - Asthma: induces bronchodilation to ease airway obstruction. - Bronchospasm: relaxes bronchial smooth muscle during acute attacks.

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

Common Side Effects: - Tachycardia - Palpitations - Headache - Nausea - Tremor - Flushing

Serious or Rare Side Effects: - Severe arrhythmias - Myocardial ischemia - Pulmonary edema - Hypotension - Anaphylactic reactions - Severe hypertension

Careful monitoring and patient assessment are essential when using Isoprenaline.

- Cardiovascular monitoring: observe heart rate and rhythm continuously during infusion. - Electrolyte balance: correct potassium or magnesium abnormalities before administration. - Ischemic heart disease: use with caution, as increased demand may precipitate angina. - Thyroid disorders: hyperthyroid patients may experience exaggerated tachycardia. - Concomitant β‑blockers: may blunt therapeutic effect and require dose adjustment. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

Isoprenaline can interact with several drug classes, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Beta‑blockers: antagonize β‑receptor stimulation, potentially causing severe bradycardia. - MAO inhibitors: may precipitate hypertensive crises when combined. - Tricyclic antidepressants: increase risk of cardiac arrhythmias.

Moderate Interactions (Monitor Closely): - Digitalis glycosides: additive effect on cardiac conduction, monitor for arrhythmias. - Diuretics: electrolyte shifts can modify cardiac response to Isoprenaline. - Theophylline: combined bronchodilator effect may lead to excessive tachycardia.
