Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/15612036 | http://www.sciencedirect.com/science/article/pii/S0010854504002371 | https://www.drugs.com/drp/custodiol-htk-solution.html | http://www.pharmanovia.com/fileadmin/user_upload/Pdf_filer/Custodiol_Package_Insert_09-04-03.pdf

Histidine is an essential amino acid. L-histidine is converted to histamine by histidine decarboxylase, a pyridoxal 5'-phosphate-dependent enzyme. The copper(II)–l-histidine (1:2 complex at physiological pH) has been widely used in the treatment of Menkes disease (a genetic neurodegenerative disorder that leads to early death in the children due to impaired copper metabolism) and more recent use has been reported in the treatment of infantile hypertrophic cardioencephalomyopathy (a condition caused by mutations in SCO2, a cytochrome c oxidase assembly gene). CUSTODIOL HTK (Histidine-tryptophan-ketoglutarate) Solution is indicated for perfusion and flushing of donor kidneys, liver, and heart prior to removal from the donor or immediately after removal from the donor.

Approved Use

3% FreAmine® III (Amino Acid Injection) with Electrolytes is designed for peripheral administration to well-nourished mildly catabolic adult patients who require only short-term parenteral nutrition. In medical or routine postsurgical patients where enteral nutrition is not desirable or cannot be tolerated, protein sparing can be achieved by the peripheral infusion of amino acid solutions with or without nonprotein calories.

Route of Administration: Oral
Histidine significantly inhibited both hydrogen peroxide- and TNF-alpha-induced IL-8 secretion and mRNA expression in Caco-2 cells and HT-29 cells. These inhibitions were dose dependent and the inhibition rate of hydrogen peroxide-induced IL-8 secretion reached more than 50% at a concentration of 25 mM, with over 95% inhibition at a concentration of 50 mM.
