Isolin 2mg Injection contains Isoprenaline sulfate, a synthetic sympathomimetic amine that primarily acts as a non-selective beta-adrenergic agonist. It is indicated for the management of bradycardia, heart block, and certain types of bronchospasm due to its potent chronotropic and inotropic effects on the heart, as well as its bronchodilatory properties. Upon administration, Isoprenaline stimulates beta-1 adrenergic receptors in the myocardium, resulting in increased heart rate and myocardial contractility, thereby improving cardiac output. Additionally, stimulation of beta-2 adrenergic receptors leads to relaxation of bronchial smooth muscles, facilitating easier breathing in obstructive airway conditions. Isolin 2mg Injection is typically administered intravenously or via intramuscular injection under strict medical supervision, with dosage tailored according to the patient’s clinical response and condition severity. Caution is advised in patients with ischemic heart disease, hypertension, hyperthyroidism, and arrhythmias. Common adverse effects may include palpitations, tremors, headache, and hypotension. Contraindications include hypersensitivity to Isoprenaline and conditions where increased cardiac workload may be detrimental. Continuous monitoring of cardiovascular and respiratory status is essential during therapy to ensure efficacy and minimize potential risks.
