To the Editor.  I have received a letter of inquiry as to the composition of pyritinol.The chemical formula of pyritinol follows: bis[3-hydroxy-4-hydroxymethyl-2-methylpyridyl-(5)-methyl]-disulfide dihydrochloride monohydrate. The structure is shown in the Figure.The references in which this information appears are Wiener Medizinische Wochenschrift (114:105, 1964); Arzneimittel-Forschung (14:26, 1964); and Med Exp (7:144, 1962).
