Epitrate Injection 1 ml contains Adrenaline 1 mg combined with Sodium Metabisulphite 0.1% w/v as a stabilizing agent. Adrenaline, also known as epinephrine, is a potent sympathomimetic agent that acts primarily on alpha- and beta-adrenergic receptors, producing vasoconstriction, bronchodilation, and increased cardiac output. This injection is indicated for the emergency treatment of anaphylaxis, cardiac arrest, and severe asthma attacks, where rapid adrenergic stimulation is essential. The vasoconstrictive properties of adrenaline help to reduce mucosal edema and improve airway patency, while its positive inotropic and chronotropic effects enhance myocardial contractility and heart rate, supporting circulation during shock states. Sodium Metabisulphite serves as an antioxidant to maintain the stability and efficacy of adrenaline in solution. Epitrate Injection should be administered intramuscularly, subcutaneously, or intravenously under strict medical supervision, with dosage adjusted according to the clinical condition and patient response. Caution is advised in patients with cardiovascular disorders, hyperthyroidism, or diabetes mellitus due to potential adverse effects such as hypertension, tachyarrhythmias, and metabolic disturbances. Proper storage and handling are necessary to preserve drug potency. This formulation is intended for professional use in emergency and critical care settings.
