Description

Curator's Comment: description was created based on several sources, including https://www.drugs.com/nda/metadoxine_170109.html | http://www.alcobra-pharma.com/products.cfm?productID=142229 | https://www.ncbi.nlm.nih.gov/pubmed/1870355

Metadoxine is an ion pair salt of pyridoxine and pyrrolidon carboxilate (PCA). Metadoxine is predominantly used in developing nations for acute alcohol intoxication. The positive effect of metadoxine on ethanol metabolism can be explained by the maintenance of normal levels of alcohol dehydrogenase during chronic ethanol intake. Metadoxine was investigated against ADHD, but FDA put hold on phase III clinical trials. Metadoxine is also investigated as a treatment for fragile X synsdome.

Sample Use Guides

In Vivo Use Guide

For treatment of fatty liver due to alcoholism, metadoxine could be administered orally, intravenously or intramuscularly. The recommended dose for oral administration is 0.5-1 g/day. The recommended dose for intravenous or intramuscular administration is 300-600 mg/day.

Route of Administration: Other

In Vitro Use Guide

The rat stomach fundus bioassay was used to assess the functional activity of metadoxine at the 5-HT2B receptor. For the antagonist assay, ex vivo tissues were repeatedly exposed to a submaximal concentration of the reference agonist 5-carboxamidotryptamine (5-CT, 0.3 μM) to obtain a control contraction, then tissues were washed. This sequence was reproduced at 40-minute intervals in the presence of increasing concentrations of metadoxine (1, 5, 10, and 20 mg/mL) added 30 minutes before the addition of 5-CT
