Uricsol is marketed by the Uricsol Chemical Company, formerly of Los Angeles, now of Boston. Regarding its composition only vague statements are made. In an advertising pamphlet it is promised that the formula will be sent to physicians on request. Such a request from a physician elicited the following statement: “URICSOL is a non-irritating, alkaline solution, containing Lithium Citrate, Acid Citric and Potassium Nitrate, together with a saline laxative in the form of Glycero Sodium Phosphate, with Vegetable Tonics added.” The Association Laboratory has made an examination of Uricsol to determine its composition and reports as follows: LABORATORY REPORT A trade package purchased in March, 1915, from a wholesale drug house was labeled: “Uricsol Rheumatic Remedy, Uric Acid Solvent, Kidney and Liver Stimulant, Manufactured by the Uricsol Chemical Co., Los Angeles, Cal.” This package was wrapped in a circular entitled “The Great California Remedy--Uricsol.” The preparation is a viscid, slightly turbid light brown liquid, with a faintly aromatic odor and a salty, bitter taste. The diluted solution is acid in reaction toward litmus and phenolphthalein and alkaline toward methyl orange. Qualitative tests showed a presence of phosphate, citrate, nitrate, sodium, glycerin, and a small amount of lithium in aqueous solution. Besides these a small amount of some organic, nonalkaloidal substance was found, which from its bitter taste suggested gentian. From the qualitative tests it appeared that the phosphate was the predominating ingredient and accordingly a phosphate determination was made. The results, calculated to sodium phosphate, U. S. P., indicated the presence of 64.20 gm. per 100 c.c., held in solution by citric acid and sodium nitrate. Uricsol evidently is a solution containing a large amount of sodium phosphate with small amounts of lithium, nitrate, citric acid and glycerin, with probably some vegetable extract. In general Uricsol is similar to the once widely exploited proprietary “Melachol,” which has been frequently imitated. A preparation essentially identical is in the United States Pharmacopeia, under the title “Compound Solution of Sodium Phosphate.” The Uricsol Company calls its preparation “... the latest word in the treatment of Rheumatism and that allied group of ailments which is caused by an excess of Uric Acid.” Hay fever, bronchial asthma and neuritis are conditions in which it is recommended. The claim is made that “Uricsol quickly controls Vasomotor Rhinitis and eliminates such conditions from the system.” “In fact, it will correct FAULTY METABOLISM.”
