N-acetyltyrosine, also referred to as N-acetyl-L-tyrosine, is used in place of as a tyrosine precursor. [DB00135] is a non-essential amino acid with a polar side group. N-acetyltyrosine is administered as parenteral nutrition or intravenous infusion due to its enhanced solubility compared to tyrosine [A32652]. It is typically administered as a source of nutritional support where oral nutrition is inadequate or cannot be tolerated.

Indication
N-acetyltyrosine is indicated, in combination with several other amino acids and dextrose, as a peripherally administered source of nitrogen for nutritional support in patients with adequate stores of body fat in whom, for short periods, oral administration cannot be tolerated, is undesirable, or inadequate [FDA Label]. It is also indicated, with other amino acids, 5-10% dextrose, and fat emulsion, for parenteral nutrition to preserve protein and reduce catabolism in stress conditions where oral administration is inadequate [FDA Label]. When administered with other amino acids and concentrated dextrose, it is indicated for central vein infusion to prevent or reverse negative nitrogen balance in patients where the alimentary tract by the oral, gastrostomy, or jejestomy routes cannot or should not be used or in patients in which gastrointestinal absorption of protein is impaired, metabolic requirements for protein are substantially increased, or morbidity and mortality may be reduced by replacing amino acids lost from tissue breakdown [FDA Label]
