Acetylcysteine Injection is an intravenous antidote for the treatment of acetaminophen overdose. Acetylcysteine is the nonproprietary name for the N-acetyl derivative of the naturally occurring amino acid, L-cysteine (N-acetyl-L-cysteine,). The compound is a white crystalline powder, which melts in the range of 104° to 110°C and has a very slight odor. The molecular formula of the compound is C 5 H 9 NO 3 S, and its molecular weight is 163.2. Acetylcysteine has the following structural formula: Acetylcysteine Injection is supplied as a sterile solution in vials containing 20% w/v (200 mg per mL) acetylcysteine. The pH of the solution ranges from 6.0 to 7.5. Acetylcysteine Injection contains the following inactive ingredients: 0.5 mg per mL disodium edetate, sodium hydroxide (used for pH adjustment), and Water for Injection, USP. The amount of sodium in Acetylcysteine Injection is approximately 30 mg per mL. Because Acetylcysteine Injection is administered based on a patient's weight, the amount of sodium administered in a course of treatment will vary from approximately 225 mg to 4,500 mg. The use of ½ normal saline will contribute approximately an additional 1,770 mg of sodium per liter of diluent. Structural Formula
