Isonly

Isoprenaline Hydrochloride, the active ingredient in Isonly, is a beta‑adrenergic agonist presented as an injectable solution for intravenous use. It is employed to raise heart rate and improve myocardial contractility in patients with bradycardia, heart block, asystole, cardiac arrest, and to relieve bronchospasm in acute respiratory distress. GNH USA supplies Isonly as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals and clinics worldwide.

Isonly, a non‑selective beta‑adrenergic agonist, is used in acute cardiovascular and respiratory emergencies. - Bradycardia: increases heart rate to restore adequate cardiac output. - Heart block: enhances atrioventricular conduction to improve rhythm stability. - Asystole: provides rapid chronotropic stimulation during cardiac arrest. - Cardiac arrest: supports circulatory resuscitation by boosting myocardial contractility. - Bronchospasm: induces bronchodilation to ease airway obstruction in emergency settings.

Isonly may cause a range of adverse reactions that vary in frequency and severity.

Common Side Effects: - Tachycardia: excessively rapid heart rate. - Palpitations: sensation of irregular or forceful beats. - Headache: mild to moderate cranial discomfort. - Tremor: fine muscle shaking, especially in the hands. - Nausea: feeling of queasiness or urge to vomit. - Hyperglycemia: transient rise in blood glucose levels.

Serious or Rare Side Effects: - Arrhythmias: potentially life‑threatening irregular heart rhythms. - Myocardial ischemia: reduced blood flow to heart muscle. - Severe hypotension: dangerous drop in blood pressure. - Pulmonary edema: fluid accumulation in the lungs. - Anaphylaxis: acute allergic reaction requiring immediate intervention.

When using Isonly, clinicians should observe several safety measures to minimise risk. - Cardiac monitoring: continuously assess heart rhythm and rate during infusion. - Dose titration: adjust infusion speed based on hemodynamic response. - Contraindications: avoid in patients with uncontrolled ventricular tachyarrhythmias. - Caution in ischemic heart disease: monitor for signs of myocardial oxygen demand exceeding supply. - Pregnancy and lactation: use only if benefits outweigh potential risks, as safety data are limited. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Isonly can interact with other agents that affect cardiovascular function or catecholamine metabolism.

Major Interactions (Avoid): - Beta‑blockers: may blunt the chronotropic and inotropic effects of isoprenaline. - Class III antiarrhythmics (e.g., amiodarone): increase risk of severe arrhythmias. - MAO inhibitors: can potentiate catecholamine‑related toxicity.

Moderate Interactions (Monitor Closely): - Calcium channel blockers: may enhance negative inotropic effects. - Diuretics: can exacerbate electrolyte disturbances, especially hypokalemia. - Antihypertensives: may require dose adjustments to maintain target blood pressure.
