Atropine Sulfate Injection, USP is a sterile, nonpyrogenic isotonic solution of atropine sulfate monohydrate in water for injection with sodium chloride sufficient to render the solution isotonic. It is administered parenterally by intravenous injection. Each milliliter (mL) contains 0.4 mg or 1 mg of atropine sulfate monohydrate equivalent to 0.332 mg or 0.83 mg of atropine, and sodium chloride, 9 mg. May contain sodium hydroxide and/or sulfuric acid for pH adjustment. 0.308 mOsmol/mL (calc.). pH 3.0 to 3.8. The solution contains no bacteriostat, antimicrobial agent or added buffer (except for pH adjustment) and is intended for use only as a single-dose injection. When smaller doses are required the unused portion should be discarded. Atropine Sulfate, USP is chemically designated 1α H, 5α H-Tropan-3-α-ol (±)-tropate (ester), sulfate (2:1) (salt) monohydrate, (C 17 H 23 NO 3 ) 2 H 2 SO 4 H 2 O, colorless crystals or white crystalline powder very soluble in water. It has the following structural formula: Atropine, a naturally occurring belladonna alkaloid, is a racemic mixture of equal parts of d-and 1-hyocyamine, whose activity is due almost entirely to the levo isomer of the drug.
