The question then arose as to the form in which the lithium and the formaldehyd are present. The statements regarding its properties as a urinary antiseptic and the fact that the preparation is said to liberate formaldehyd slowly in the bladder point strongly to the presence of hexamethylenamin. Tests[102] were applied to demonstrate whether the formaldehyd was present as a lithium compound, and if not, whether it existed in the form of hexamethylenamin. By these the presence of hexamethylenamin was proved and the absence of formaldehyd in other combinations demonstrated. This fact alone shows that the preparation is deliberately marketed under a false claim, and it shows further that the analysis on the label is worthless. The quantitative method of analysis demonstrated the presence of 5.51 gm. hexamethylenamin per 100 c.c. (25.15 grains per fluidounce). [102] These appear in the annual report for 1908 of the Chemical Laboratory of the American Medical Association; they were also published in full in Jour. Am. Chem. Soc., September, 1908; an outline of the analysis appeared in The Journal A. M. A., Aug. 29, 1908. Besides the hexamethylenamin, Uriseptin contains lithium and a benzoate. Concerning the latter nothing is said in the analysis, whose worthlessness is again demonstrated. By quantitative methods Uriseptin was found to contain lithium and a benzoate in such proportions as would indicate that the lithium and the benzoate radicle exist as lithium benzoate. This fact is further indicated by the claims made for the preparation regarding its properties as a uric acid solvent, for which purpose lithium benzoate is often used. Again, the demonstration that the formaldehyd present is in combination as hexamethylenamin precluded any possible chemical combination between lithium and formaldehyd and adds another strong point in support of the conclusion that the lithium and benzoic acid are in combination as lithium benzoate. CONCLUSION By chemical analysis the active ingredients of Uriseptin are shown to be hexamethylenamin, approximately 5.5 gm. per 100 c.c. (about 25 gr. to each fluidounce), and lithium benzoate, approximately 0.70 gm. per 100 c.c. (about 11 grains to each fluidounce), neither of which compounds is mentioned in the advertising matter on the label or in the so-called “analysis” on the label. The statements concerning the composition of Uriseptin are false and appear to be a deliberate attempt to mislead physicians.
