Medical Properties And Therapeutic Uses

These lithium salts have strong alkaline properties, and produce effects similar to those of the potassium and sodium compounds; and hence are very effective antacid agents. The salts of lithium are employed with great benefit in rheumatic gout, uric acid diathesis, rheumatism, uric acid calculi of kidneys and bladder, irritable bladder from an excess of acid in the urine, etc.

Dental Uses

The lithium salts are effective in preventing and correcting the effects of a gouty diathesis upon the teeth, and in periodontitis dependent upon gout. The carbonate of lithium is employed to arrest the abrasion or erosion of the teeth, when due to an excess of uric acid in the saliva; for such a purpose the agent can be dissolved in carbonic acid water.
