Atropine Sulfate (CAS 55-48-1)/ Antispasmodic

Atropine Sulfate (CAS 55-48-1) is a high-purity pharmaceutical API, a classic antimuscarinic agent that competitively blocks muscarinic acetylcholine receptors. Its alkaloid-derived structure acts on smooth muscles, secretory glands, and the central nervous system, inhibiting parasympathetic activity to produce multiple therapeutic effects. Unlike specialized anticholinergics, it offers broad utility—from relieving spasms to emergency antidote use—making it a staple in clinical settings.

As a colorless or white crystalline powder with excellent water solubility, it suits diverse formulations including injections, tablets, and ophthalmic preparations. It meets the core needs of general pharmaceutical manufacturers, emergency medicine suppliers, and clinical supply chains. Widely used as an antidote for organophosphate poisoning, it also relieves visceral colic, treats symptomatic bradycardia, reduces perioperative secretions, and aids ophthalmic dilation. Produced under strict GMP standards, each batch undergoes rigorous purity, stability, and receptor-blocking activity testing to meet USP/EP requirements, ensuring reliable clinical performance.
