Isoprenalin Macure

Isoprenaline, the active ingredient in Isoprenalin Macure, is a non‑selective beta‑adrenergic agonist presented as an intravenous solution for acute cardiovascular and respiratory use. It is employed to increase heart rate and contractility in bradyarrhythmias, to support cardiac output during heart block or cardiac arrest, and to produce bronchodilation in severe asthma attacks. The drug acts rapidly when administered by infusion and is typically used under close clinical monitoring in hospital settings.

GNH USA supplies Isoprenalin Macure as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Isoprenalin is used in conditions that require rapid stimulation of beta‑adrenergic receptors to improve cardiac output or airway patency. - Bradyarrhythmias: raises heart rate to restore adequate perfusion. - Heart block: increases conduction through the AV node to improve rhythm. - Cardiac arrest (adjunct): supports circulation while definitive resuscitation measures are applied. - Bronchial asthma: relaxes bronchial smooth muscle to relieve acute bronchospasm.

Isoprenalin may cause a range of adverse reactions, from mild to severe, depending on dose and patient sensitivity.

Common Side Effects: - Tachycardia: rapid increase in heart rate. - Palpitations: awareness of heart beating. - Tremor: fine muscle shaking. - Headache: mild to moderate pain. - Nausea: feeling of sickness. - Hyperglycemia: elevated blood glucose levels.

Serious or Rare Side Effects: - Arrhythmias: abnormal heart rhythms, including ventricular tachycardia. - Myocardial ischemia: reduced blood flow to heart muscle. - Severe hypotension: dangerous drop in blood pressure. - Pulmonary edema: fluid accumulation in lungs. - Allergic reactions: rash, itching, or anaphylaxis. - Cardiac arrest: loss of effective heart function.

Use of Isoprenaline requires careful assessment of cardiovascular and respiratory status. - Cardiac monitoring: continuous ECG and blood pressure observation. - Dose titration: adjust infusion rate to achieve target heart rate. - Contraindications: avoid in patients with severe tachyarrhythmias or uncontrolled hypertension. - Caution in diabetes: monitor blood glucose due to possible hyperglycemia. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

Isoprenaline can interact with other agents that affect adrenergic tone or cardiac conduction.

Major Interactions (Avoid): - Beta‑blockers: antagonize therapeutic effects and may precipitate severe bradycardia. - Calcium channel blockers (verapamil, diltiazem): increase risk of heart block and hypotension. - MAO inhibitors: may potentiate hypertensive responses.

Moderate Interactions (Monitor Closely): - Diuretics: may exacerbate electrolyte disturbances, affecting cardiac rhythm. - Antidiabetic drugs: monitor for hyperglycemia. - Inhaled bronchodilators: additive bronchodilation may cause tachycardia. - Anesthetics: potential for exaggerated cardiovascular responses.
