Epinephrine bitartrate CAS No. 51-42-3

Product Description

Epinephrine bitartrate is the pharmaceutically-stable tartrate salt of epinephrine (adrenaline), a synthetic catecholamine that appears as a white, water-soluble powder supplied at ≥ 97 % pharmaceutical-grade purity. After reconstitution it functions as a non-selective α- and β-adrenergic agonist, rapidly increasing heart rate and contractility, dilating bronchi, and constricting blood vessels. These actions make it the front-line emergency drug for anaphylaxis, cardiac arrest, severe hypotension, and refractory asthma; it is also added to local anesthetics to slow their systemic absorption and prolong regional block. The powder is stable for two years when kept sealed, dry, and at room temperature, but because the drug can provoke tachycardia, tremor, and anxiety it must always be administered under professional supervision and in strict accordance with clinical protocols.
