What is Atropine Sulfate?

Target Species:

Active Ingredients: Atropine Sulfate

Atropine Sulfate Injection is a drug used before anesthesia to decrease salivation and other respiratory secretions. It is also used in the treatment of bradycardia, mushroom poisoning, and cholinergic drug overdose. Atropine also decreases intestinal peristalsis which may be caused by colic or diarrhea.

Atropine is a naturally occurring substance found in deadly nightshade, Jimson weed, and mandrake. It is generally considered to be an anticholinergic or anti-parasympathetic drug. Atropine also displays anti-muscarinic properties. This drug works by inhibiting smooth muscles and glands, and it also relaxes the GI tract and decreases the activity of the urinary tract.

This formulation of Atropine Sulfate has been manufactured as a sterile, nonpyrogenic isotonic solution. Sodium chloride has been added to render the solution isotonic. It is important to note that this product is for veterinary purposes only. It should be prescribed by a veterinary doctor or animal care specialist for an animal.
