atropine and pralidoxime chloride - Generic Medications

Each prefilled ATNAA is a single-dose autoinjector that provides an intramuscular dose of atropine, a cholinergic muscarinic antagonist, and pralidoxime chloride, a cholinesterase reactivator, in a self-contained unit, specifically designed for automatic self- or buddy-administration by military personnel. When activated, each ATNAA injection delivers the following: 2.1 mg of atropine in 0.7 mL of sterile, pyrogen-free solution containing 12.47 mg glycerin, not more than 2.8 mg phenol, 3.05 mg sodium citrate dihydrate, 3.5 mg citric acid monohydrate, and Water for Injection. The pH range is 4.0 – 5.0. 600 mg of pralidoxime chloride equivalent to 476.6 mg of pralidoxime in 2 mL of sterile, pyrogen-free solution containing 40 mg benzyl alcohol, 22.5 mg glycine, and Water for Injection. The pH is adjusted with hydrochloric acid. The pH range is 2.0 – 3.0. After ATNAA has been activated, the empty autoinjector should be disposed of properly [see Dosage and Administration (2.2) ] . It cannot be refilled, nor can the protruding needle be retracted. Atropine occurs as white crystals, usually needle-like, or as a white, crystalline powder. It is slightly soluble in water with a molecular weight of 289.38. Atropine, a naturally occurring belladonna alkaloid, is a racemic mixture of equal parts of d- and l-hyoscyamine, with activity due almost entirely to the levo isomer of the drug. Chemically, atropine is designated as 1αH,5αH-Tropan-3α-ol (±)-tropate. Its empirical formula is C 17 H 23 NO 3 and its structural formula is as follows: Pralidoxime chloride is an odorless, white to pale-yellow crystalline powder, freely soluble in water, with a molecular weight of 172.61. Chemically, pralidoxime chloride is designated as 2-formyl-1-methylpyridinium chloride oxime. Its empirical formula is C 7 H 9 CIN 2 O and its structural formula is indicated above.
